How to use a combo box custom keystroke script to call a function

Question

I simply want to use a combo box custom keystroke script to call a function when any item is chosen from the box's list. I found many examples and tried many unsuccessfully. My most recent attempt is this:

if(event.changeEx != ""){this.ConcessionMaximum()}

Also tried referencing the export values (there are only three in the list) like this:

if(event.changeEx == "con" || event.changeEx == "fha" || event.changeEx == "va"){

this.ConcessionMaximum();

}

Apologies for what seems a very elementary question, but I would appreciate a solution.

If you have export values it won't work with validate script, try using custom calculation script instead.

Your original script should work fine as keystroke script, are you sure you have right export values, also maybe it's issue in your function script perhaps?

Having export values does not prevent a custom validation script for working for this purpose. You just need to use the display value in the code, instead of the export value.

A validation script runs whenever the value of the field containing the script changes, so all you have to do is enter your function as a validation script.  You don't need any conditions.  If you don't tick "Commit select value immediately" in the options tab, the function will execute upon the blur event.  If you do tick it, the function will execute immediately after making a selection.
