When you’re creating a web form, it’s often the case that you want to give the user a way to connect one entity up to another entity. This post explains how to do this in a nice, clean way using Spring Formatters.
A real-life example
To make things concrete, let’s use a real-life example. I’m working on an open source CMDB called Zkybase that has entities such as farms, environments and data centers. When the user creates or edits a farm, he needs to specify the environment in which the farm lives (e.g., Development, Test, Production, etc.) and also the data center (e.g., US West DC 1, US West DC 2, etc.). We want the user to select an environment and a data center using dropdowns, like so:
For edits, we obviously want the dropdowns to be preset to their current values. We want validation: in our example, all three fields are required. For both edits and creates, when the user submits an invalid farm (e.g., missing name), we want the environment and data center to be preset to whatever value the user just submitted. Standard stuff.
Let’s look at three different approaches to solving this in Spring. The first two are ugly and the last one is clean. (If you’re impatient, feel free to skip right to the third approach.)
Approach #1 (ugly): ad hoc ID fields
One approach is to create special fields on the Farm
entity to hold the environment and data center IDs, and then write custom code in the controller to map these to Environment
and DataCenter
instances. Here’s how such a Farm
might look:
public class Farm { private Long id; private String name; private Environment environment; private DataCenter dataCenter; private Long environmentId; private Long dataCenterId; ... getters and setters for id, name, environment and dataCenter ... @NotNull @Transient @XmlTransient public Long getEnvironmentId() { return environmentId; } public void setEnvironmentId(Long id) { this.environmentId = id; } @NotNull @Transient @XmlTransient public Long getDataCenterId() { return dataCenterId; } public void setDataCenterId(Long id) { this.dataCenterId = id; } }
And the form code looks something like this (I’m suppressing some details just for clarity’s sake):
<form:select path="environmentId"> <form:option value="" label="-- Choose one--" /> <form:options items="${environmentList}" itemValue="id" itemLabel="name" /> </form:select> <form:errors path="environmentId"> <form:errors path="environmentId" /> </form:errors>
The approach works, but it’s stinky for at least a couple of reasons:
- It dirties up the `Farm` entity. We already have `Environment` and `DataCenter` properties, and each of those has an ID, so it’s redundant and annoying to have to include extra getters and setters to handle the IDs. If we’re doing ORM or OXM, it becomes very clear from the `@Transient` and `@XmlTransient` annotations that these extra ID properties aren’t really part of the entity at all; they’re purely supporting data transfer.
- It forces us to write custom code in the controller to map the IDs to an `Environment` and a `DataCenter` so we can, e.g., save it in the database using Hibernate or whatever.
Now let’s see a closely related approach that’s a step in the right direction, but still stinky.
Approach #2 (still ugly): use the referenced entities’ ID properties
Instead of using redundant ID properties, we can just leave the Farm
alone (meaning it has an ID, a name, an environment and a data center, and no extra ID properties) and just point the form at the environment’s and data center’s IDs:
<form:select path="environment.id"> <form:option value="" label="-- Choose one--" /> <form:options items="${environmentList}" itemValue="id" itemLabel="name" /> </form:select> <form:errors path="environment.id"> <form:errors path="environment.id" /> </form:errors>
Spring is fine with complex properties like this. And so this almost works. But there are once again a couple of issues:
- Stylistically, it’s a bit inelegant to treat reference-backed properties in a special way. It would be cleaner to deal with `environment` and `dataCenter` instead of `environment.id` and `dataCenter.id`. Minor issue, but still worth considering.
- More seriously, validation (at least JSR-303 validation) doesn’t work properly anymore. Referencing `environment.id` in the form causes Spring to create an `Environment` instance automatically, even if the user picks “– Choose one –” with ID = “”. So the `environment` and `dataCenter` properties won’t ever be null. And we can’t put `@NotNull` on the environment and data center IDs, because they’re allowed (indeed, expected) to be null when creating new ones. So you end up having to write custom code to make sure that the IDs are whatever you want to see. Blech.
OK, those are some approaches that aren’t very clean. Fortunately Spring 3 has some features that clean things up.
Approach #3 (good approach): use Formatters
The best practice approach in Spring 3 is to use so-called Formatters
. As this blog post is already pretty long, let’s just jump right into the code. If you want to see more code details, check out the actual code at the Zkybase Github site.
First, our entities don’t have any ad hoc ID properties like we saw in approach #1 above. But you do need to implement equals()
for your entities, or else form prepopulation won’t happen.
Next, here’s what the form looks like:
<form:select path="environment"> <form:option value="" label="-- Choose one--" /> <form:options items="${environmentList}" itemValue="id" itemLabel="name" /> </form:select> <form:errors path="environment"> <form:errors path="environment" /> </form:errors>
(Same thing for the dataCenter
property.) Notice that we’re not messing around with IDs at all, other than where we’re telling the <form:options>
tag which property to use for the option value, which is perfectly fine and legitimate.
Next we need to look at the controller. In earlier versions of Spring we would have had to register some JavaBeans PropertyEditor
s in an @InitBinder
method, but we don’t have to do that anymore. All we have to do is make sure we’re prepared to accept a Farm
in our handler method, that we annotate it with @Valid
, etc.:
@RequestMapping(value = "/{id}", method = RequestMethod.PUT) public String putEditForm( @PathVariable Long id, @ModelAttribute("formData") @Valid Farm formData, BindingResult result, Model model) { ... }
The method body doesn’t matter so much for our current purpose—we can check for validity using result.hasErrors()
, save the data if it’s valid, return the invalid form if it’s not, or whatever. The main thing is that the Farm
will come populated with an Environment
and a DataCenter
(both having the right IDs set) if the user chose them, and they’ll be null if the user didn’t:
To make the magic work, we need to implement Formatter
s to convert our environments and data centers back and forth to IDs. Regarding Formatter
s, I’ll let you read about them in the Spring Reference Documentation; here I’ll give some code examples. Here’s the EnvironmentFormatter
:
package org.zkybase.formatter; import java.text.ParseException; import java.util.Locale; import org.zkybase.model.Environment; import org.springframework.format.Formatter; import org.springframework.stereotype.Component; @Component public class EnvironmentFormatter implements Formatter<Environment> { @Override public String print(Environment environment, Locale locale) { return environment.getId().toString(); } @Override public Environment parse(String id, Locale locale) throws ParseException { // IMPORTANT: This approach works only if your equals() method doesn't compare fields // beyond the ID. If it does, then you'll need those fields set too. Consider simply // loading the entity from the database. Environment environment = new Environment(); environment.setId(Long.parseLong(id)); return environment; } }
One more thing we have to do is configure the formatters in our Spring configuration. Here’s what that looks like (Spring 3.0.6+; I’m suppressing the namespace declarations):
<context:component-scan base-package="org.zkybase.formatter" /> <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> <property name="formatters"> <set> <ref bean="dataCenterFormatter" /> <ref bean="environmentFormatter" /> </set> </property> </bean> <mvc:annotation-driven conversion-service="conversionService" />
This tells Spring Web MVC to use the conversion service both when rendering the form and when processing submitted form data. We won’t go into all the gory details here since they’re not necessarily important to making the whole thing work, but the formatter’s print()
method is the one that handles form rendering, and the formatter’s parse()
method handles turning the IDs in the HTML into entities in the Java controller.
Quick tip regarding Firefox. Before I close, I wanted to offer a quick tip. When you’re implementing and troubleshooting this stuff, be aware that Firefox has a feature where it remembers your most recently submitted form values when you hit the refresh button instead of resetting the form to its default settings. The feature helps users avoid data loss, but for developers it’s a pain because you have to reload the page from the actual address bar (click in there and hit Enter) instead of refreshing the page. I didn’t know this and the form was not responding to my code changes in the way I expected.


This page will link you to some of the seminal articles, posts, videos, podcasts, etc. around data mesh. We want this to serve as a jumping off point, not the end-all, be-all. As always, feedback is welcome.
An obvious piece is by Zhamak Dehghani (LinkedIn; Twitter), who created the concept of data mesh, with the introduction of the data mesh concept from May 2019 here.
I think a great next step is a post by Sven Balnojan (LinkedIn) called Data Mesh Applied. It walks through how you might actually put together a data mesh. There are a few very key concepts Sven covers, one of which is "domain teams usually consider their data a byproduct that they don’t really own it". Think of data mesh as being similar to DevOps, where development teams have to care much more about the operations of their applications than they did previously. Data mesh isn't DataOps but it might be DevDQ (data quality) or DevDU (data usability). I am hoping for DevDUX (data user experience) for bad duck puns...
Zhamak updated her thinking about the data mesh in another post called "Data Mesh Principles and Logical Architecture" on Martin Fowler's blog here in December 2020; she drills furhter down into key pillars of the data mesh concept: a self-serve data platform, data as a product, domain ownership, and federated governance.
Here is a great conversation between Zhamak and Sam Ramji of DataStax (LinkedIn; ran Google's Kubernetes business and introduced data mesh concept at Autodesk) on Sam's Open Source Data podcast. It is more of a general chat about data mesh without being so much of a brain dump so you can absorb it a bit easier; link
Zalando, a large fashion retailer in Europe, talks about their journey to data mesh in this 30min presentation. Starting at 8:34, they specifically mention the concept of poor data ownership/data as a by-product Sven talked about above as a big pain point.
Other Zhamak presentations:
Xconf - I love this one because I think it really walks through things from start to finish in a very soup-to-nuts way; video. 40min
QCon - a talk that really kicked off the big wave of data mesh thinking and content in 2020, a general overview of data mesh and the genesis behind it; video. 50min


Tooling Up
It all begins with the right tools. Take the time to set yourself up for success from the start and it will make all the difference down the road.
Linux v.s. Mac v.s. Windows
Professional software developers need to align themselves with the best tools available to get their job done. If you’re a .NET developer or work a lot with Microsoft products then Windows is an obvious choice. Everyone else should be on some kind of Linux distrubution or a Mac. The best software tools are just typically harder to access and work with on Windows. If you’re following this journey I recommend you use Linux or Mac. I personally use Fedora but there are plenty other great options available, Ubuntu is a great alternative.

Installing Tools and Knowing their Versions
As a software developer it’s important to know your tools. You should know exactly what tools are being used, where they are installed and what versions they are. It’s important that we install these tools in a uniform and systematic way.
Install SDKMAN!
SDKMAN is a great tool for installing the software needed for developing our Spring applications. It allows you to install multiple versions (called candidates) of software at the same time and allows you to easily switch between them. SDKMAN will persist data in your home directory ~/.sdkman.
Install: SDKMAN
Read: SDKMAN usage
Install Java and Kotlin
We can build Spring with Java and Kotlin so install both using SDKMAN.
$ sdk install java
$ sdk install kotlin
Install Maven and Gradle
Spring developers depend on a number of different tools to deliver software. As a professional developer one of the first you’ll need is a build and dependency management tool. The two biggest names in the community now are Maven and Gradle. Maven has been around longer with more example code and is really stable. Gradle is relatively new, adopted strongly by the Android community and is showing a lot more power than Maven as of late. Both will get the job done but the community is favoring Gradle.
Read: zeroturnaround: Java Build Tools: How Dependency Management Works
Install Maven and Gradle with SDKMAN.
$ sdk install maven
$ sdk install gradle
Follow these exercises and ignore the part about installing Maven or Gradle because you’ve already obtained it with SDKMAN!.
- Exercise: spring.io: Building Java Projects with Maven
- Exercise: spring-guides: Building Java Projects with Gradle
Install Spring Boot Command Line Interface (Spring CLI)
The Spring Boot CLI is a tool that can help you rapidly prototype applications right from the terminal. It can be used to run Spring-Boot groovy scripts and init your application with the Spring Starter projects.
Install Spring Boot CLI with SDKMAN.
$ sdk install springboot
Follow this quick example to start a groovy web-app instantly from the command-line.
Install IntelliJ
jetbrains: IntelliJ has become the standard IDE used by most Java developers, Eclipse being the other.

mod_auth_dbm.c
file, and
is not compiled in by default. It provides for user authentication using
DBM files.
The AuthDBMGroupFile directive sets the name of a DBM file containing the list of user groups for user authentication. Filename is the absolute path to the group file.
The group file is keyed on the username. The value for a user is a comma-separated list of the groups to which the users belongs. There must be no whitespace within the value, and it must never contain any colons.
Security: make sure that the AuthDBMGroupFile is stored outside the document tree of the web-server; do not put it in the directory that it protects. Otherwise, clients will be able to download the AuthDBMGroupFile unless otherwise protected.
Combining Group and Password DBM files: In some cases it is easier to manage a single database which contains both the password and group details for each user. This simplifies any support programs that need to be written: they now only have to deal with writing to and locking a single DBM file. This can be accomplished by first setting the group and password files to point to the same DBM:
AuthDBMGroupFile /www/userbase
AuthDBMUserFile /www/userbase
The key for the single DBM is the username. The value consists of
Unix Crypt-ed Password : List of Groups [ : (ignored) ]
The password section contains the Unix crypt() password as before. This is
followed by a colon and the comma separated list of groups. Other data may
optionally be left in the DBM file after another colon; it is ignored by the
authentication module. This is what www.telescope.org uses for its combined
password and group database. See also AuthName, AuthType and AuthDBMUserFile.
The AuthDBMUserFile directive sets the name of a DBM file containing the list of users and passwords for user authentication. Filename is the absolute path to the user file.
The user file is keyed on the username. The value for a user is the crypt() encrypted password, optionally followed by a colon and arbitrary data. The colon and the data following it will be ignored by the server.
Security: make sure that the AuthDBMUserFile is stored outside the document tree of the web-server; do not put it in the directory that it protects. Otherwise, clients will be able to download the AuthDBMUserFile.
Important compatibility note: The implementation of "dbmopen" in the apache modules reads the string length of the hashed values from the DBM data structures, rather than relying upon the string being NULL-appended. Some applications, such as the Netscape web server, rely upon the string being NULL-appended, so if you are having trouble using DBM files interchangeably between applications this may be a part of the problem.
See also AuthName, AuthType and AuthDBMGroupFile.
Setting the AuthDBMAuthoritative directive explicitly to 'off'
allows for both authentication and authorization to be passed on
to lower level modules (as defined in the Configuration
and modules.c
file if there is no userID or
rule matching the supplied userID. If there is a userID
and/or rule specified; the usual password and access checks will
be applied and a failure will give an Authorization Required reply.
So if a userID appears in the database of more than one module; or if a valid require directive applies to more than one module; then the first module will verify the credentials; and no access is passed on; regardless of the AuthAuthoritative setting.
A common use for this is in conjunction with one of the basic auth
modules; such as mod_auth.c
.
Whereas this DBM module supplies the bulk of the user credential
checking; a few (administrator) related accesses fall through to
a lower level with a well protected .htpasswd file.
Default: By default; control is not passed on; and an unknown userID or rule will result in an Authorization Required reply. Not setting it thus keeps the system secure; and forces an NCSA compliant behaviour.
Security: Do consider the implications of allowing a user to allow fall-through in his .htaccess file; and verify that this is really what you want; Generally it is easier to just secure a single .htpasswd file, than it is to secure a database which might have more access interfaces.

Young Hong Kong Protester Refuses to Surrender
by AGENCE FRANCE-PRESSEHONG KONG (AP) — Pale and thin, a teenager wandered the nearly deserted campus of Hong Kong Polytechnic University at 1 a.m. Wednesday. He hugged his body with his arms, whether because of the chill in the air or gnawing worry.
Only a handful of protesters remain at Poly U, which hundreds occupied for several days, fighting pitched battles with police on the surrounding streets. Now authorities have cut off the campus and are arresting anyone who comes out.
The teen, who wouldn’t give his age but said he is under 18, is one of the holdouts. He figured he had slept about 10 hours in total since arriving at the campus about five days earlier. He said he had eaten only two biscuits all day because his mind was too distracted, obsessed with one thought: How am I going to get out?
He arrived at Polytechnic late last week, heeding a call for support from protesters who were occupying five major universities in Hong Kong. It was Thursday or Friday — the days and nights have become such a blur that he kept asking an interviewer what day it was.
Like many protesters, he spoke on condition of anonymity, fearing arrest, and would appear on camera only with his face covered.
The campus takeovers were the latest escalation in an anti-government movement that has divided the city for more than five months. The protesters’ demands include fully democratic elections and an investigation of police brutality.
In the mind of the teen, as for many, the police have become as big a problem as the government.
Riot officers began raining tear gas on their defense line outside the university Saturday night, before battering them repeatedly with water cannons and tear gas Sunday afternoon.
The teen jumped into the fray. He joined others wielding umbrellas — they call them shields — and taking the brunt of the often pepper-spray-laced bursts of water.
Three times he faced the barrages, dashing inside the campus stronghold after each attack to wash off the stinging water, change his clothes and return for the next round.
“I was at the very front,” he said. “It hit me straight on and I was soaked. If I hadn’t been wearing a jacket, my whole body would have felt like it was burning. Just my lower body really stung, and the water also got all over my face and into my eyes.”
It’s one of the roles of the frontline protesters, who engage the police directly. Wearing gas masks, they throw Molotov cocktails and snuff out tear gas canisters to try to keep the police at bay.
He acknowledges that others may see their actions as aggressive — the police call them lawbreaking rioters — but he says their role is important because the government didn’t back down when hundreds of thousands of people peacefully marched in the streets in the summer.
“If it was just the peaceful protests, it wouldn’t succeed,” he said. “Already back in June, we saw that it was just peaceful protests, and the government wouldn’t listen.”
By Sunday evening, the police had approached from all directions, setting up a cordon around the area. They warned that everyone inside would be subject to arrest.
Some protesters tried to escape on Monday and Tuesday; most were caught or repelled. The government offered to let those under 18 leave without facing immediate arrest, though their identities would be recorded and they could be charged later.
Worried family members reached out to their children. The teen got WhatsApp messages from his parents, his stepmother and others asking him to give up. Police allowed religious leaders onto the campus to make similar pleas.
Others turned themselves in. The teenager wasn’t swayed. He said he prefers to fight with all the strength he has. Surrendering would show that he had given up the fight and agrees with the government and the police, he said.
“Even if you get arrested or die, you know that you’ve tried your best and you’ve got no regrets,” he said.
And so he waits, as the hours turn into days, with less and less company around him.

Tree gets new lease of life
by DHNSWith the effort of environmentalists, a tree, which would have been felled for widening the NH 169 (A), has been relocated.

To facilitate the work on widening of the National Highway from Karavali Junction to Parkala Devi Nagara, several trees will be felled.

Some keys, such as the left arrow key, insert key, delete key, and function keys do not produce ordinary character values. These keystrokes are returned by getch as special values. See Appendix D for these values.
This means that you can call the function by calling getch or by calling Input.getch.


parse method
Parses a string as a data
URI.
The string must have the format:
'data:' (type '/' subtype)? (';' attribute '=' value)* (';base64')? ',' data
where type
, subtype
, attribute
and value
are specified in RFC-2045,
and data
is a sequence of URI-characters (RFC-2396 uric
).
This means that all the characters must be ASCII, but the URI may contain percent-escapes for non-ASCII byte values that need an interpretation to be converted to the corresponding string.
Parsing checks that Base64 encoded data is valid, and it normalizes it to use the default Base64 alphabet and to use padding. Non-Base64 data is escaped using percent-escapes as necessary to make it valid, and existing escapes are case normalized.
Accessing the individual parts may fail later if they turn out to have content that can't be decoded successfully as a string, for example if existing percent escapes represent bytes that cannot be decoded by the chosen Encoding (see contentAsString).
A FormatException is thrown if uri
is not a valid data URI.
Implementation
static UriData parse(String uri) {
if (uri.length >= 5) {
int dataDelta = _startsWithData(uri, 0);
if (dataDelta == 0) {
// Exact match on "data:".
return _parse(uri, 5, null);
}
if (dataDelta == 0x20) {
// Starts with a non-normalized "data" scheme containing upper-case
// letters. Parse anyway, but throw away the scheme.
return _parse(uri.substring(5), 0, null);
}
}
throw FormatException("Does not start with 'data:'", uri, 0);
}

Seatbelt
Seatbelt is by far the meatiest project being released. It’s a clearinghouse of situational awareness “safety checks”. That is, it manages the collection of host data that may be interesting from both offensive and defensive perspectives. Think everything from PowerShell security settings, to current user Kerberos tickets, to deleted Recycle Bin items, and more (40+ current checks!)
Seatbelt draws on a TON of existing work, highlighted in the README.md, and has already proven itself to be pretty useful on our engagements. It was heavily influenced by @tifkin_‘s Get-HostProfile.ps1 and @andrewchiles‘ HostEnum.ps1 PowerShell scripts.
SeatBelt.exe system collects the following system data:
BasicOSInfo – Basic OS info (i.e. architecture, OS version, etc.)
RebootSchedule – Reboot schedule (last 15 days) based on event IDs 12 and 13
TokenGroupPrivs – Current process/token privileges (e.g. SeDebugPrivilege/etc.)
UACSystemPolicies – UAC system policies via the registry
PowerShellSettings – PowerShell versions and security settings via the registry
AuditSettings – Audit settings via the registry
WEFSettings – Windows Event Forwarding (WEF) settings via the registry
LSASettings – LSA settings (including auth packages)
UserEnvVariables – Current user environment variables
SystemEnvVariables – Current system environment variables
UserFolders – Folders in C:\Users\
NonstandardServices – Services with binary paths not in C:\Windows\
InternetSettings – Internet settings, including proxy configs
LapsSettings – LAPS settings, if installed
LocalGroupMembers – Members of local admins, RDP, and remote DCOM groups
MappedDrives – Currently mapped drives
RDPSessions – Current incoming RDP sessions
WMIMappedDrives – Mapped drives via WMI
NetworkShares – Network shares
FirewallRules – Deny firewall rules, “full” dumps all
AntiVirusWMI – Registered antivirus (via WMI)
InterestingProcesses – “Interesting” processes- defensive products and admin tools
RegistryAutoLogon – Registry autologon information
RegistryAutoRuns – Registry autoruns
DNSCache – DNS cache entries (via WMI)
ARPTable – Lists the current ARP table and adapter information (equivalent to arp -a)
AllTcpConnections – Lists current TCP connections and associated processes
AllUdpConnections – Lists current UDP connections and associated processes
NonstandardProcesses – Processes with binary paths not in C:\Windows\
If the user is in high integrity the following additional actions are run:
SysmonConfig – Sysmon configuration from the registry
SeatBelt.exe user collects the following user data:
Checks if Firefox has history files
Checks if Chrome has history files
TriageIE – Internet Explorer bookmarks and history, last 7 days
SavedRDPConnections – Saved RDP connections, including username hints
RecentRunCommands – Recent “run” commands
PuttySessions – Interesting settings from any saved Putty configurations
PuttySSHHostKeys – Saved putty SSH host keys
RecentFiles – Parsed “recent files” shortcuts, last 7 days
If the user is in high integrity, these checks are run for ALL users instead of just the current user.
Miscellaneous checks:
CurrentDomainGroups – The current user’s local and domain groups
Patches – Installed patches via WMI (takes a bit on some systems)
LogonSessions – User logon session data
KerberosTGTData – ALL TEH TGTZ!
InterestingFiles – “Interesting” files matching various patterns in the user’s folder
IETabs – Open Internet Explorer tabs
TriageChrome – Chrome bookmarks and history
TriageFirefox – Firefox history (no bookmarks)
RecycleBin – Items in the Recycle Bin deleted in the last 30 days – only works from a user context!
KerberosTickets – List Kerberos tickets. If elevated, list all grouped by all logon sessions.
4624Events – 4624 logon events from the security event log
4648Events – 4648 explicit logon events from the security event log
SeatBelt.exe all will run ALL enumeration checks, can be combined with full.
SeatBelt.exe [CheckName] [CheckName2] … will run one or more specified checks only (case-sensitive naming!)
SeatBelt.exe [system/user/all/CheckName] full will prevent any filtering and will return complete results. By default, certain checks are filtered (e.g. services NOT in C:\Windows\, etc.)
Here’s an example of some of the system collection:

The Item Display Panel Service may be used to show and hide the Item Display Panel without using the directive. This is useful when more programmatic control over the display panel is required.
An example of this service is shown in the Tree Grid documentation.
To use the service, inject $displayPanel
into the controller. This provides the following
functions:
element
- the HTML element which is being displayed, e.g. tr
element in
a table.itemDisplayPanelOptions
- the options for the display panel, as documented in the
Item Display Panel section.shadow
- a boolean argument determining whether a shadow effect appears underneath the
title header of the display panel.previous
- a boolean argument indicating whether there is a previous item to switch
to; useful if navigation buttons are used within the display panel.next
- a boolean argument indicating whether there is a next item to switch to; useful
if navigation buttons are used within the display panel.itemDisplayPanelOptions
- the options for the display panel, as documented in the
Item Display Panel section.animate
setting is used then the panel will be hidden
instead of closed.
element
with which the open
function was called.
Puts the browser focus on the previous sibling of the element
which was passed to the open
function, if there is one. Note that this function will not directly update the display panel contents.
It takes one optional argument:
selector
- a jQuery selector expression to match elements against.element
which was passed to the open
function, if there is one. Note that this function will not directly update the display panel contents.
It takes one optional argument:
selector
- a jQuery selector expression to match elements against.
