What do you mean content of an a tag? You can do this like so:
$('#linkElementID').html();
or get an attribute like so:
$('#linkElementID').attr("title"); //Title Attribute
$('#linkElementID').attr("href"); //href Attribute etc etc
I don't think there is an event that is fired when a tag changes, the .change()
event is only fired by input areas and select lists.
You would need to check after the event that loads the newly inserted content.
