Ajax jQuery , beginner question

I'm trying to make an ajax call to grab session data to insert into my page after it's loaded like this

jQuery(function(){ // Add Answer

  jQuery(".add_answer").livequery('click',function(){
    var count = $(this).attr("alt");
    count++;
    var count1 = count-1;

    $.get('quiz/select', function(p_type){  // Ajax Call for Select Data

      $(this).parents('div:first').find('.a_type_'+count1+'').after('' + p_type + '');
      $(this).attr("alt", count);

    });
  });
});

The file i'm calling is found but its contents are not printed out by 'p_type' and the $(this).attr("alt", count); part of the function is not executing

Note: I'm using CodeIgniter for my framework and jquery for js

From stackoverflow

• I believe your problem has to do with the scope of $(this). Because you've got your ajax get function nested inside your livequery function, inside yet another anonymous function, I'd be willing to bet that $(this) is now refering to your $.get() call or something.

  You need to cache $(this) as soon as possible at the point where you know it has the correct object selected:

  jQuery(".add_answer").livequery('click',function()
  {
      var add_answer = $(this);
  
      $.get(...)
      {
          add_answer.parents('div:first')...
      }
  }
  

  The above code should cache the add_answer element, but my livequery knowledge is a bit rusty.

  Some recommendations on your code:

  • Be consistent with the use of either jQuery() or $() shortcuts, they do the same thing.
  • What's with the anonymous function surrounding the whole snippet? Is that just for a simplified example? It should probably be replaced with a $(document).ready(function { ... });
  Kevin Gorski : Using $(function() { ... }) is equivalent to $(document).ready(function { ... });

  Soviut : you're right. I've always found $(document).ready() to be clearer in its intentions.

• "this" is a special keyword in Javascript. In your outer function it refers to .add_answer element. And in your inner function it refers to window.

  jQuery(".add_answer").livequery('click',function(){
    var self = this;
    // ...
    $.get('quiz/select', function(p_type){
      // ...
      $(self).attr("alt", count);
