jQuery Resizable and Draggable Tutorial with Example

Have you ever tried doing some animation using plain Javascript or moving DIVs here and there or resizing them?! Well, you know then how much pain it is as not only you have to tackle the difficult part of animation but also making it cross browser compatible.

Well you probably know why I am stretching up so hard is just to tell you how easy it is to use jQuery and do some really fantastic things without even bothering of knowing how it is done internally. jQuery comes with really useful UI library that can be incorporated to do such tricks.

In this small note, I will show you how to do Resizing and Dragging of a DIV using jQuery UI. I will show you the demo of a DIV, which can be resized by pulling up the edges and also dragged here and there.

Step 1: Setting up jQuery UI and CSS

We need to install jQuery UI library first in order to do resizing/dragging. Add following lines in your HEAD of html document.

<script type="text/javascript" 
<script type="text/javascript" 
<link rel="stylesheet" type="text/css" 

Note that we have imported jquery and jquery-ui library. Also, to use Resizable we must import jquery-ui.css file. This stylesheet will be used by resizable to add resize corner and other internal styles.

Step 2: Write jQuery to Resize and Drag

For the demo we will define a small DIV which we will make resizable and draggable.

<div id="resizeDiv"></div>

Now just add following jQuery code in your document.


The beauty of jQuery is that we can simply chain the function calling. First we called .draggable() function that makes the DIV draggable and then we called resizable().
You may want to define callback functions on start/stop/resize events. To do so we simply define:

		start: function(e, ui) {
			alert('resizing started');
		resize: function(e, ui) {

		stop: function(e, ui) {
			alert('resizing stopped');

Note that the callback function gets two arguments. First is event object and next is ui.
The ui object has the following fields:

  • ui.helper – a jQuery object containing the helper element
  • ui.originalPosition – {top, left} before resizing started
  • ui.originalSize – {width, height} before resizing started
  • ui.position – {top, left} current position
  • ui.size – {width, height} current size
