How to disable field based on condition on form load in uipath forms?

I came across a problem where if a field has value already present, it needs to be disabled.

I tried to use Logic with simple JavaScript trigger but I’m not sure when this trigger is evaluated, but the trigger is executed onchange or onblur.

Trigger: enter image description here

Action: enter image description here

This works but since trigger executes onblur or onchange, as soon as I type some characters the field is disabled.

It should execute only once on form load. I have tried adding a hidden HTML component but calling the onload function is not working.

HTML component code:

<!DOCTYPE html>
<html>
<body onload="myFunction();">
<script>
function myFunction() {
if(document.getElementById('empName').innerHTML.length > 0)
  {
    document.getElementById('empName').setAttribute('disabled ', 'disabled');
  }
}
</script>
</body>
</html>

I'm not very good with JavaScript or have used form.io before. Also, I could not understand how to use Trigger type Event and call it externally. Thanks for the help.

You can set the dependent field by:

  1. Setting the logic trigger to be of 'Simple' type and check the parent field to have '' (blank) value.
  2. Have the logic action setup as you have already done
