I wrote a snippet that will check for the change of an element on an event.

So if you are using third party javascript code or something and you need to know when something appears or changes when you have clicked then you can.

For the below snippet, lets say you need to know when a table content changes after you clicked a button.

$('.button').live('click', function() {

            var tableHtml = $('#table > tbody').html();
            var timeout = window.setInterval(function(){

                if (tableHtml != $('#table > tbody').
                    console.log('no change');
                } else {
                    console.log('table changed!');
                    clearInterval(timeout);
                }

            }, 10);
        });

Pseudo Code:

• Once you click a button
• the html of the element you are expecting to change is captured
• we then continually check the html of the element
• when we find the html to be different we stop the checking
