Which of the following code is better in building a delete -action for removing a question?

1 My code

<a href='index.php?delete_post=777>delete</a>

2 Stack Overflow’s code

<a id="delete_post_777>">delete</a>

I do not understand completely how Stack Overflow’s delete -button works, since it points to no URL.
The id apparently can only be used by CSS and JavaScript.
Stack Overflow apparently uses JavaScript for the action.

  1. How can you put start the delete -action based on the content of CSS -file by JavaScript?
  2. How can you start a SQL delete -command by JavaScript? I know how you can do that by PHP, but not by JavaScript.

    The url you are looking for is in the js code. Personally I would have an id that identifies each <a> tag with a specific post, comment… or whatever, and then have a class=”delete_something” on each one, this then posts to the correct place using javascript.

    Like so:

    <a href="#" class="delete_post" id="post_111" title="Delete Post">Delete</a>

<script type="text/javascript">
jQuery('a.delete_post').live('click', function(){

    jQuery.post('delete.php', {id: jQuery(this).attr('id')}, function(data){
        //do something with the data returned
    })
});
</script>
