Javascript is setting field value then lookup rule not working

Version 10

Hi,

In Forms 10.2 I'm using javascript to set the value of a field, then I'm trying to use that field as a condition to populate a dropdown list, but it's not working.

If I change the the field value manually, even to the same value that the JS is providing, the lookup is successful.

Anyone know of a way to get the lookup rule to"see" that the JS has set a value?

When you set the value, you need to trigger a change event, which in turn triggers the lookup.

For example,

$('#q1 input').val('test').change();

Adding the .change() at the end of where you set the value should solve your problem.

As a side note, if you don't trigger the change event, you might lose the data after the form is submitted. I had this problem in the past, not sure if 10.2 changed that, but I've made a habit of triggering the change anyway to avoid problems with lookups, field rules, etc.
