How can I set the size of custom field "Text Field" from javascript in jira?

[Raju KC]

Can I set the size of custom field "Text Field (< 255 characters)" to 50 Chars from javascript in jira?

[Nadir MEZIANI · Accepted solution]

In the field description, add this

<script type="text/javascript">

document.getElementById("customfield_xxxxxx").maxLength=50;

</script>

where
customfield_xxxxxx is the id of your
Text Field

When I try the code above nothing happens. Only difference is I'm checking a field length of 5.

I guess I'll try a Script Runner transition, but why doesn't the javascript fire?

If I put an alert in the javascript, an alert pops up on the screen right when I hit save. Why would that happen, I haven't entered and data yet!

I came across this and follow the following instruction for JIRA Server :

https://confluence.atlassian.com/jirakb/how-to-change-text-box-length-on-a-screen-ui-in-jira-732399321.html

I used the following css for the field Environment for ex:

#environment-val /* The "id" of the "Environment" text box */
{ 
    margin: -2px 0 0 -5px; 
    width: 100%; 
}

Hi,

I have a similar requirement that, i have to set the width of the customefield(Number field). But, using the above javascript in the field description does not serve the purpose.

Please help with the same

That's work fine for me in v5.1 jira.

Or simply add a validator using Script Runner, rather than doing it in javascript (which can break anytime, and it is just a client side validation)

Thanks!

But, how can i achieve that? I need complete guide to that.
