Rule not firing onchange event

I've added the event Core - Data Element Change and in custom code consoling it out. The data element name is 'form Abandonment' and js object is digitalData.form.formAbandonment
if(digitalData.form.formAbandonment != ""){
console.log("Refresh case:"+_satellite.getVar("form Abandonment"));
return true;
} else {
console.log("Not updated");

return false;
}

I tried consoling out the same value in datalayer and I'm getting the right values for both js and satellite object. The formAbandonment is set on unload event.
$(window).on( "unload", function() {
formArray['formAbandonment'] = fieldName;
});
)};

What is most likely happening is that there's a "race condition" between when your digitalData.form.formAbandonment gets set vs when the browser has already unloaded and is navigating to the next page. You can verify if this is the case with the Adobe Experience Platform Debugger's Events panel.

With window's unload function, one "trick" I've used that works pretty consistently is to perform the Rule's action within a condition. Basically, run the action's custom code in a condition, and make sure the last line is "return true;".

@jezwna Data Element Change event might not be the best for you.

Try using a Custom Code event. In there, you can use:

window.addEventListener('beforeunload', function (event) { trigger(); // REQUIRED });

Then, you can read from your data element in a condition or action.
