Time for action — fixing our delete post function to work with pagination


When we added the pagination, we also broke the ability to delete posts that are loaded via AJAX. This is because we are using the bind event handler to tie the click event to our links, which only happens on page load. So, we'll need to account for the links loaded via AJAX. Thankfully, we can do that using jQuery's live event handler.

  1. 1. Open master.js, and change the delete post code to use live instead of bind:

    $('.delete').live( 'click', function(event){
    
    event.preventDefault();
    var location = $(this).attr('href');
    
  2. 2. If you start deleting a bunch of items in the post list, it currently doesn't change the number of posts tied to a user account using JavaScript. While we are here, let's alter the success function so that it also updates the number of posts at the top of our post list:

    $('.delete').live( 'click', function(event){
    event.preventDefault();
    var location = $(this).attr('href');
    $.ajax({
    type: 'DELETE...
