How to target only youtube iframe urls?

Question

I'm looking for a way to target this jquery only at src url's that have "youtube.com" in them. I've tried using the :contains selector but I can't get it working correctly.

jQuery(document).ready(function($){

    $('iframe').each(function() {
        var url = $(this).attr("src")
        $(this).attr("src",url+"&wmode=transparent")
    }); 

});

Use the attribute selector to target only iframes with a src containing youtube.com:

jQuery(document).ready(function($){

    $('iframe[src*="youtube.com"]').each(function() {
        var url = $(this).attr("src")
        $(this).attr("src",url+"&wmode=transparent")
    }); 

});
