Referencing value of alert box

Question

I'm trying to write a rule that conditions on the content of a javascript alert box. That is, I'm trying to fire a conversion script if the alert says "submission successful" vs "some error message". Can I access the string shown in the alert box so I can use it ie if alert message == "submission successful" fire the tracking script?

You could override alert so that you could track what is being alerted. For example:

window.alert = (function() {
 var existingAlert = window.alert;
 return function(message) {
   console.log(message);        // do your tracking here
   existingAlert(message);
 };
})();

You would need to be able to run this code before other code called window.alert .
