I have an a ajax method that hijacks every link in the HTML and preventDefault and then loads the loadPage function().

The method works on all other links that does not have a <img> inside. But when a <a> has a <img> inside the method clickEvent.target.href does not seem to work.

The var url in this instance returns undefined in the console, but on any other links it returns the href.

I'm guessing there is something wrong with I use the target method in this instance?

$('#container a').click(function(clickEvent){
         var url = clickEvent.target.href;
         if(url.match(urlWebServer)) {
                     clickEvent.preventDefault();
                     loadPage(url);
         }
});



<div id="user_img">        
    <a href="somepage.html"><img src="img_user/self.jpg" class="self" /></a>
</div>

Reset to default 10

Yes, you shouldn't use the clickEvent.target because is the target that was clicked. In your case the target isn't the a but is the img it contains.

Events in fact bubble up, so you click the image and the click event propagates to the top (up to the a) and triggers the event delegate you provided.

The solution is to change that line to

var url = this.href;

Or if you prefer to get the value through jQuery use

var url = $(this).attr('href');

The first one is faster.

The solution is that this in the handler refers to the DOM element you attach the handler to. So this will refer to the a.

If you use jQuery to select and bind, why not use jQuery for the rest of your action?

$('#container a').click(function(event){
     var url = $(this).attr('href');
     if(url.match(urlWebServer)) {
                 event.preventDefault();
                 loadPage(url);
     }
});

That's because clickEvent.target refers to the element which received the click, not the element to which the event listener was attached. Use this instead, which corresponds to the correct element.

var url = this.href;

Also note that you don't need to do $(this).prop or $(this).attr; you can safely access the .href property of an anchor element without needing to create another jQuery instance and call another method.

The target is the actual element that event was triggered on, which can be any of the children of the element you attached it to.

Use this to reference the link instead.

var url = $(this).prop("href");
