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

Answer 1

There is a trace function is console is provided by all major browsers. console.trace();

With Proxy approach, as described in earlier answers, and console.trace(), we can print the entire stack with line number in console itself.

(function(proxied) {
  window.alert = function() {
	console.trace();
    return proxied.apply(this, arguments);
  };
})(window.alert);

This is an IIFE. Every alert call will have its trace printed in the console.
