If you want to manipulate with the DIV inside the $.get function, you can declare a local variable and put the reference to DIV in it...
(function($) { $.fn.myPlugin = function() { this.each(function() { alert(this.id); var that = this; $.get("return.php",function(data) { // now "this" is "that" alert(that.id); //do something with "this" & the "data" }); }); return this; }; })(jQuery); You don't have to call the variable "that", but it's a nice name, isn't it? :)
