Why does Javascript non always pre-populate Summary field

DI2E Licensing

In a field configuration for one of our projects, we have the following in the Summary description:

 

<script type="text/javascript">
AJS.$("#summary").val("Group Membership Request");
</script>

In the create screen, sometimes the Summary field gets pre-populated and sometimes is doesn't.

Any ideas?

 I don't know javascript to save my life.  I copied and pasted this from some other source.  I'm happy to solve this some other way.   

Thanks.

possible reason:

your javascript code is running when the DOM document (page) is still rendering.

Sometimes youre lucky and the element with id #summary has already been rendered. Then your script is picking it up and rewriting the value as intended.

Sometimes however it is possible that the #summary element has not been rendered when your script is running. Therefore it is unable to locate the #summary element and does nothing.

 

possible solution:

try embracing the population code into document.ready event handler.

this ensures, that the script is running only when the page has finished rendering.

<script type="text/javascript">
AJS.$(document).ready(function() {
    AJS.$(document).bind('dialogContentReady', function(event, dialog) {
        AJS.$("#summary").val("Group Membership Request");                
    });
});
</script>

PS: Elements that appear in pop up dialogs are missing even when document is finished rendering.

To pick them you should bind your preopulation code to dialogContentReady event.

Try this.
