How to call a jQuery object from within its own chain

Question

If I had a jQuery object and wanted to call itself, is there any better way of doing that then like…

$("#notes").text($("#notes").data("defaulttext"));

I mean… I know I can do something like

var $notes = $("#notes");

to speed up things a bit, but I was just wondering if there is any variable I could use that means "the object I am currently working on", instead of manually typing in the object name again.

The $(this) method doesn't work. I actually tried that before posting my question. I was hoping for something that simple, though. — Dan Goodspeed

Pass a function inside .text() method and in that function return your object's data attribute using this object

$("#notes").text(function(){
    return $(this).data("defaulttext")
    });

Or in order to be less ugly you can create a plugin using

$.fn.edit = function() {
this.text(this.data('defaulttext'));
return this;   //to maintain chainability
};

and then use like

 $("css_Selector").edit();

to change the text of element to its data-defaulttext attribute

How about this?: $("#notes").text($(this).data("defaulttext")); will this refer to #notes?

The latter $(this) method doesn't work. I actually tried that before posting my question. I was hoping for something that simple.

Well you can use the first one then

Yeah, it just gets pretty ugly when I put together a big chain of methods doing the first one. Thanks, though.
