从Chrome开发者工具暂停警报框上的JavaScript执行

Question

I am debugging a complex webpage which is throwing an alert box on clicking a particular element. I want to locate the code which is causing this. It is difficult to search my codebase by looking for message shown in alert box as it is very vague and dynamic. Is it possible to pause JS execution on alert in debugger from the Chrome dev tools or any other debugger? (In a similar way like Chrome allows to pause JS execution on events like click, etc).

I already tried reaching the code by pausing on click event, but there are too many JS files to step through and the code is minified and complex.

Thanks.

Take a look at this snippet

 (function() { var _old_alert = window.alert; window.alert = function() { //breakpoint _old_alert.apply(window,arguments); }; })(); alert('hey'); alert('you'); alert('there'); 

You can try to override alert function, put a breakpoint and take a look at Call Stack to figure out where it comes from.
