parsing [Object] return .load jquery from php

Question

I have this :

 p['record_id'] = 2;
 $('#trcode').val($(this).load('url_to_PHP_methode',p,function(str){}));

The value returned from PHP method is like this -> "Just String"

In firebug, there is correct response value, "Just String", but in text input with ID #trcode it shows [object Object].

So, my question is: How to show the correct return value just like Firebug "Just String"?

Answer 1

.load() is for loading content into an element, it returns the jQuery object (for chaining), which is why you see the "[object Object]" string you do now.

Instead, what you want is to use $.get() and use the response, like this:

$.get('url_to_PHP_methode', function(str) {
  $('#trcode').val(str);
});
