Question

I want to simulate a onclick function on all images in a page.
the problem is each img has a unique onclick call and also the img does not have an ID or class.

Each img is within a div:

<div id="339949822">
<img src="button.png" onclick="addUser('339949822');">
</div>

Answer 1

With jquery:

$("img[onclick]").each(function(index, element){
  eval( $(element).attr("onclick") );
});
