I'm using Tohin's Jquery Pagination: http://tohin.wordpress.com/2008/10/07/co...guideline/

Almost PHP code is follow their guildline.

and JS in HTML side:

Code:

[removed]
    $(document).ready(function(){
        $(".delete_id").click(function(){
            alert(this.attr("id").val());
            $.ajax({
                type: 'POST',
                url: 'http://localhost/jpage/index.php/welcome/ajax_page/',
                data: 'delete_customer_id=' + this.attr("id").val(),
                success:
                    function(data){ $('#content').html(data); return false; }
            });
        });
    });
[removed]
[removed]
    function serialize_form() { return $("#myform").serialize(); }
[removed]

The firebug is point error to:

Code:

$(document).ready(function(){

and said "$ is not defined"

Ya, im have double check in FireBuy, Jquery.min.js is loaded and store in cache too.

Thank you for your all helping. I know the reason. Im adding "defer" element in JQuery include script.
