Jira Calendar date time value JavaScript validation with Jira format

Hi All,

Is there a way to validate the Calendar popup value with the Jira format?

Scenario is: Users pick a date time with calendar popup and value is "10/Oct/17 1:15 PM". But after user manually modifies value as "NotValid10/Oct/17 1:15 PM". Now date is not valid and I want to warn to user immediately. Is there any way to validate the date input in Jira user profile date format with javascript without going to backend service?

Here is the velocity client code:

#macro(datePopup $inputId $inputButton $showTime $dateFormat)
<script language="javascript" xmlns="http://www.w3.org/1999/html">
firstDay : 1,
inputField : '$inputId',
button : '$inputButton',
align : 'Br',
singleClick : true,
showsTime : $showTime,
useISO8601WeekNumbers : false,
ifFormat : '$dateFormat'

<input type="text" id="date_101" class="text input-medium field-value-editor" style="width:180px !important;" value="$attributeValue"/>
<img id="date_trigger_101" class="field-value-editor" src="$requestContext.baseUrl/images/icons/cal.gif" width="16" height="16" border="0" alt="Pick a date"/>
#datePopup("date_101" "date_trigger_101" false "%e/%b/%y %I:%M %p")


Date format is based on JIRA settings, it is not hard-coded. And JIRA date and date time settings are based on Java Simple Date format for Java and Unix format for JS. I can not find a JS library to validate any of these formats.


As I inspected JIRA, JIRA posts the data to the backend and validates there.

I googled and I couldn't found a stable library. Moment.js format is different and Calendar JS has no method to validate.

Any help is appreciated.
