Setting the value of a "Message Custom Field" (not for edit) by JavaScript

[Chris K.]

I'm using a "Message Custom Field" and what I want to do is have it display the current issue's ID + Summary. If I use the below code in the CF description, it works fine if I'm setting just a regular single-line text field. However if change the custom field to the "Message Custom Field", it doesn't change the value.

<script type="text/javascript">
  summary = document.getElementById('summary');
  issue_key = AJS.Meta.get("issue-key");
  target = document.getElementById('customfield_10002');
  target.style.display = '';
  target.value=issue_key + " " + summary.value;
</script>

Do you change the value of a Message Custom Field differently than a regular custom field? That's the only thing I can think of. Any help would be greatly appreciated. Thanks!

Message custom fields do not have a value - they draw their data from the default value and then have nothing to display for the actual value - the velocity file basically just says "$default-value"

Injected Javascript is a clunky, messy and unmaintainable way to do anything with JIRA and should be avoided - stripping it all out is usually the first thing an experienced JIRA admin will do to an inherited system.  You should really use the functions the field provides - it supports velocity internally, so all you really need is to put "$issue.getKey() $issue.getSummary()" in the default value.

Thanks, NIc. Yeah, injecting JS wasn't my first choice...we're just using it as a stop-gap till we can create a proper plugin. Can you point me somewhere that shows the proper syntax for velocity? I tried putting exactly what you have above as the default value: $issue.getKey() $issue.getSummary() And it just displayed the above string literally. Thanks!!

Hi Nick,

I must have read a few hundred of your responses over the last couple of years as a JIRA admin, you're a bit of a ledge :)

I'm having the same trouble as Chris, those $ values are displayed literally and are not taken from the current issue dynamically.

Any clues? I've searched around for ages without success.

I put a simple "alert" box script in the Default Value field and the script ran fine so the JS is being called. I'm assuming then it's the way that I'm trying to set the value...
