How to find what is causing a preventDefault which overrides normal click behavior

rated 0 times [ 48] [ 1] / answers: 1 / hits: 8111 / 11 Years ago, tue, december 10, 2013, 12:00:00

I've inherited some large piece of code. Somewhere inside a way too generalised e.preventDefault() is prohibiting the normal behavior of an anchor click.

I thought about running profiler in Chrome webtools to see what is happening when clicking on a particular link, hoping to trace it back to the culprit statement. However I haven't had much luck

how can I trace back (if possible) a statement that is overriding normal click behavior, when clicking a link in Chrome webtools?
(I am using jQuery)

You should be able to override Event.prototype.preventDefault and add a debugger statement as its first line.

Run the following via the console.

var oldEPD = Event.prototype.preventDefault;

Event.prototype.preventDefault = function() {

    debugger;

    oldEPD.call(this);

};
