Question

As in the Question text, how can I get the last action performed on document using jQuery.
For example I have changed element class as below

  $('.highlight').toggleClass();

How can know that which element was the target of last change in a document

Answer 1

You could create a custom event and trigger it each time ?

$('.highlight').toggleClass().trigger('somethingChanged')

Then listen for the triggered event

$(document).bind('somethingChanged', data, function(){ do stuff });
