How to find out where the alert is raised from?

Question

I\'m just curious to know
Is there ANY ways in ANY browser to find out where the alert I get is raised from?

I tried it in chrome but there is no call stack availabl

You can overwrite alert, and create an Error for the stack trace:

var old = alert;

alert = function() {
  console.log(new Error().stack);
  old.apply(window, arguments);
};
