How Can I Detect Changes in DOM Element Content Beyond jQuery\'s `change()` Function?

Detecting DOM Element Content Changes with jQuery

The jQuery change() function effectively detects changes in form element values. However, what if you need to monitor changes in a DOM element's content, such as when using $("#content").html('something')?

The Dilemma

The change() function is unsuitable for this purpose because content changes in non-form elements originate from code. Therefore, relying on it would require you to manually check for the element's content at specific intervals.

Alternative Approaches

1. Chain jQuery Methods and Traversal:

If performing simple DOM manipulation, consider chaining jQuery methods and traversing. For instance:

$("#content").html('something').end().find(whatever)....

2. Custom Event and triggerHandler:

For more complex actions, utilize jQuery's bind function with a custom event and triggerHandler.

$("#content").html('something').triggerHandler('customAction');

$('#content').unbind().bind('customAction', function(event, data) {
   //Custom-action
});

This approach allows you to define a custom action that will be executed when the "customAction" event is triggered.
