Open link in new window with Jquery

Question

I am trying to open a few links in a new window using Jquery rather than _blank so my html remains valid. My code looks like this:

$(document).ready(function() {
    $('a[id="external-url"]').click(function(){
        $(this).attr('target','_blank');
    });
});

This works just fine except when the link is contained within html I have placed on the page using the Jquery load() method. Can anyone explain why and please help with a solution?

Update: If you're reading this in an HTML5+ world the target attribute is no longer deprecated (no longer missing, to be more accurate) as it was in XHTML 1.0 (the original question context). I suggest if you're reading this now, ignore everything below, use the target attribute whether it throws a compliance warning or not, all browsers support it and it never should have been left out...the fact it was added back in a later spec shows removing it was a mistake.

This will work:

$('a#external-url').live('click', function(){
  $(this).attr('target','_blank');
});

However, IDs should be unique, if you're loading more than 1, they need to have a class instead, like this:

<a href="http://google.com" class="exteral-url">Google</a>

And jQuery like this:

$('a.external-url').live('click', function(){
  $(this).attr('target','_blank');
});

The standards compliant way would be:

$('a.external-url').live('click', function(e){
  window.open(this.href);
  e.preventDefault(); //or return false;
});
