With the evolution of JIRA over the years, it has a set of nice APIs or helper methods for doing pretty much everything. But one thing that I always have to look up while developing plugins is using date and user pickers in a velocity template.
As usual, it is something that is really easy once you look it up. Here is a simplified version of what I have done in the last few versions of JIRA.
As usual, it is something that is really easy once you look it up. Here is a simplified version of what I have done in the last few versions of JIRA.
Let us create a sample plugin with a simple webwork action. How about an alias of Picker? Is there a more obvious name to call this example? ;)
<webwork1 key="picker-module" name="PickerModule" i18n-name-key="picker-module.name">
<description key="picker-module.description">Sample date and user picker in velocity templates</description>
<actions>
<action name="com.jtricks.jira.webwork.Picker" alias="Picker">
<view name="success">/templates/picker-module/picker/success.vm</view>
</action>
</actions>
</webwork1>
As you can see, we just have a simple webwork actions and a velocity template associated with the success view. All we are going to do here is to create a form in the view with sample picker fields. I have generalized methods so that you can use it for as many picker fields as you want on the same page.
Date Picker field
Really easy to do this! Couple of steps:
1. Add this macro in the beginning of the template.
#macro(datePopup $inputId $inputButton $dateFormat)
<script language="javascript" >
Calendar.setup({
firstDay : 1,
inputField : '$inputId',
button : '$inputButton',
align : 'Br',
singleClick : true,
showsTime : false,
useISO8601WeekNumbers : false,
ifFormat : '$dateFormat'
});
</script>
#end
2. Use the macro in the field group as shown below:
<div >
<label for="uniqueDateId">Date Field Name</label>
<input id="uniqueDateId" name="name" />
<a href="#" id="uniqueDateId_trigger" title="Enter your date field">
<span ></span>
</a>
#datePopup("uniqueDateId" "uniqueDateId_trigger" $dateFormat)
</div>
That's it!
As you can see, the input field has a unique id (uniqueDateId in this example) and the anchor tag has a matching id which of the format ${id_of_input_field}_trigger (uniqueDateId_trigger in this example). Make sure pass this input field Id and anchor id to the datePopup macro we created in step 1.
The result is what you can see here:
DateTime Picker field
This is much similar to Date field, except for the number of arguments passed to the macro. It takes a date time format and a time format as opposed to the date format. Following are the steps:
1. Add a macro similar to what we did earlier.
#macro(dateTimePopup $inputId $inputButton $dateTimeFormat $timeFormat)
<script language="javascript" >
Calendar.setup({
firstDay : 1,
inputField : '$inputId',
button : '$inputButton',
align : 'Br',
singleClick : true,
showsTime : true,
useISO8601WeekNumbers : false,
ifFormat : '$dateTimeFormat',
timeFormat : '$timeFormat'
});
</script>
#end
The main difference is the formats. In the script, ifFormat uses a date time format instead of date format. There is also a timeFormat argument. Also showsTime argument is true instead of false.
2. Use the macro similar to what we did for datePopup. The unique ids should be just like what we did there.
<div >
<label for="uniqueDateTimeId">DateTime Field Name</label>
<input id="uniqueDateTimeId" name="name" />
<a href="#" id="uniqueDateTimeId_trigger" title="Enter your date time field">
<span ></span>
</a>
#dateTimePopup("uniqueDateTimeId" "uniqueDateTimeId_trigger" $dateTimeFormat $timeFormat)
</div>
Unique input id is uniqueDateTimeId and anchor id is uniqueDateTimeId_trigger. Here is how the field will appear on screen:
User Picker field
User picker is slightly different. Here we make use of JIRA's user picker browser where you can search for users based on name, email or group.
In the page, we click on the user picker icon to open up the user picker browser as a popup window and when you click on the search result, it fills the form back with the result selected.
Steps are as follows:
1. Add a javascript function that opens up the user picker
<script language="javascript" >
function openUserPickerWindow(element){
var vWinUsers = window.open('$!requestContext.canonicalBaseUrl/secure/popups/UserPickerBrowser.jspa?formName=jiraform&multiSelect=false&element=' + element, 'UserPicker', 'status=yes,resizable=yes,top=100,left=200,width=580,height=750,scrollbars=yes');
vWinUsers.opener = self;
vWinUsers.focus();
}
</script>
The openUserPickerWindow method just opens up a user picker browser popup with the element attribute as the source input id (element variable). Note that the formName in the example is jiraform and change it as appropriate.
2. Invoke the function when you click on the user picker icon.
<div >
<label for="uniqueUserId">User Field Name</label>
<input id="uniqueUserId" name="lead"/>
<a href="javascript:openUserPickerWindow('uniqueUserId');">
<img title="Ente the user name" name="multiuserImage" src="$!requestContext.canonicalBaseUrl/images/icons/filter_public.gif" hspace="0" height="16" width="16" border="0" align="absmiddle" >
</a>
</div>
Here also the input field has a unique id (uniqueUserId in the example) and that is passed in the anchor tag. You can change the icon as you want in the image tag.
Once added, the field appears on the form like this:
When you click on the user browser icon, it opens up the popup as shown below:
When you click on the 'admin' row, uniqueUserId on the form is populated as shown.
Yeah right, you have seen it a lot in JIRA ;)
The example code is uploaded at the end of the tutorial and you can run the webwork action using the URL http://localhost:2990/jira/secure/Picker.jspa.
That's all. 3 simple pickers, easy steps. How about the Ajax user search? Well, some other day :P
