Javascript on selecting from a dropdown list

Post by claude vidal » Sat Nov 03, 2018 6:58 pm

What is the trigger for a selection from a dropdown list?

I'm trying to set values other fields on that form based on what was selected from a given dropdown list.

I've assigned a Javascript to that dropdown field on every trigger available (Mouse: down, up, enter, leave, focus, blur); Javascript console active. Nothing triggers.

What do I need to do?

Hello Claude Vidal,

You will need to put the JS in "Keystroke Action":

And the code I am using in one of my salmes looks something like:

Code: Select all

if (event.willCommit) 	
this.getField("SomeOtherFieldName").value = event.value + "your custom value";
