Ajax jquery success scope

Question

I have this ajax call to a doop.php.

    function doop(){
        var old = $(this).siblings(\'.old\').html();
        var new = $(this).siblin         


        

Answer 1

First of all new is a reserved word. You need to rename that variable.

To answer your question, Yes, you need to save this in a variable outside the success callback, and reference it inside your success handler code:

var that = this;
$.ajax({
    // ...
    success: function(resp) {
        if(resp == 1) {
            $(that).siblings('.old').html($new);
        }
    }
})

This is called a closure.
