Nested jQuery loop with Rails loop

I'm trying to nest a jQuery loop within a Rails loop but am not having any luck. The here is the rails:

<% entry.videos.each do |video| %>
    <input type="hidden" class="url" value="<%= video.url %>">
    <div class="videos" src=""></div>
<% end %>

and the jQuery:

$('.url').each(function () {
    var urlThumb = $.jYoutube($(this).val(), 'small');
    var url = $(this).val();
    $('.videos').append($('<div class="vidya"><a href="'+url+'" rel="prettyPhoto" class="youtubeLink"&g开发者_如何学编程t;<img src="'+urlThumb+'" class="overlay"/></a></div>'));
            });

where jYoutube is just a method to grab a thumbnail from a youtube video.

The issue is that rather that inserting the thumbnail into the respective entry, it inserts all thumbnails into all entries with a video.

You can use siblings function to filter the corrsponding div with videos class.

e.g:

$('.url').each(function(){
 var urlThumb = $.jYoutube($(this).val(), 'small');     
 var url = $(this).val();     
 $(this).siblings('.videos').append
 (
  $('<div class="vidya"><a href="'+url+'" rel="prettyPhoto" class="youtubeLink"><img src="'+urlThumb+'" class="overlay"/></a></div>')
 );    
}); 

Try this I am not sure

$('.url').each(function (index) {
    var urlThumb = $.jYoutube($(this).val(), 'small');
    var url = $(this).val();
    $('.videos').append($('<div class="vidya"><a href="'+url+'" rel="prettyPhoto" class="youtubeLink"><img src="'+urlThumb+'" class="overlay"/></a></div>'));
});
