use $(this) in ajax callback jquery

Question

i\'m doing a jQuery.post to a php file, and the file return\'s me a value.

the question is: why the $(this) dosent work in the callback fun

Answer 1

In that case this is not the same object anymore. Save a reference before and use later:

$(".class").live("focusout", function(){
    var $this = $(this);
    jQuery.post("phpfile.php",
       {
           someValue: someValue
       },
       function(data)
       {
           // 'this' inside this scope refers to xhr object (wrapped in jQuery object)
           var x = $this;
       }                
    )
});

Answer 2

$(".class").live("focusout", function(){
    var this = $(this);
    jQuery.post("phpfile.php",{
       someValue: someValue
   },function(data){
        // Now use this instead of $(this), like this.hide() or whatever.
   })
});

$(this) in your example was refering to the $.post i think.
