Jquery: Add rel attribute to <a> tags within all <li> tags of a certain class

I'm trying to add a rel="lightframe" attribute to all my 'edit' links within my admin_links_node_edit class.

<li class="admin_links_node_edit">
<a href="[link]" title="Edit">Ed开发者_如何学运维it</a>
</li>

My code so far looks like this:

$('.admin_links_node_edit a').each(function() {
        $(this).attr('rel','lightframe'); 
});

You don't need to use each(). jQuery's selectors will do it for you :)

$('.admin_links_node_edit a').attr('rel', 'lightframe')

The above code will do the trick.

If admin_links_node_edit is reused among other elements, you'll want to specify the element you're working on (li in this case). In addition, as Vijay Dev said, each() isn't needed, as attr() works on every element in the selector. Therefore:

$("li.admin_links_node_edit a").attr('rel','lightframe');
