As “there are tens of thousands of cells in the page” binding the click-event to every single cell will cause a terrible performance problem. There’s a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:
$('body').click(function(e){ var Elem = e.target; if (Elem.nodeName=='td'){ //.... your business goes here.... // remember to replace $(this) with $(Elem) } })
This method will not only do your task with native “td” tag but also with later appended “td”. I think you’ll be interested in this article about event binding & delegate
Or you can simply use the “.on()” method of jQuery with the same effect:
$('body').on('click', 'td', function(){ ... });
