ajax repeats previous requests

I'm working with codeigntier and i'm trying some stuff with ajax. This is somewhat difficult to explain.

I have a controller Products with a method "overview", and a view "products_overview".

This is the controller

This is the view

My problem is, is when I make the ajax call in the view in this part:

$('body').delegate('#notification-close', 'click', function(){
    $('#notification').fadeOut(200, function(){
        $('#notificati开发者_运维问答on').remove();
    });

    $('#blanket').fadeOut(200).remove();

    $.ajax({
        type: 'GET',
        url: '<?php echo $current_get_url; ?>',
        success : function (result) {
            $('#column-middle').html(result);
        }
    });

});

It doubles the ajax call everytime i use it. And something else. The products controller creates pagination links. When I go back and forth a few times, I also make ajax calls. Let's say I do that 4 times. Then, when I use the above ajax call, it will execute those 4 previous calls and then start doubling from that!

So, i'm kind of lost here. When I put a setTimeout on $('#column-middle').html(result), it will execute once, but then give a jQuery error that "result" is not defined.

You should return false from a delegate handler function to stop event bubbling, e.g.:

$('body').delegate('#notification-close', 'click', function(){
    // processing

    // stop further handlers from executing
    return false;
});

See caveats section here. You can also abuse closure scope properties to prevent call doubling:

var column_middle_working = false;
$('body').delegate('#notification-close', 'click', function(){
    if (column_middle_working) return;
    column_middle_working = true;
    // do what you do

    $.ajax({
        type: 'GET',
        url: '<?php echo $current_get_url; ?>',
        success : function (result) {
            $('#column-middle').html(result);
            column_middle_working = false;
        }
    });

});

But still recommend you finding a real reason of this behavior.

Have you tried adding undelegate('click')?

$('body').undelegate('click').delegate('#notification-close', 'click', function(){
    $('#notification').fadeOut(200, function(){
        $('#notification').remove();
    });

    $('#blanket').fadeOut(200).remove();

    $.ajax({
        type: 'GET',
        url: '<?php echo $current_get_url; ?>',
        success : function (result) {
            $('#column-middle').html(result);
        }
    });

});
