// Using DragResize is simple!

// You first declare a new DragResize() object, passing its own name and an object

// whose keys constitute optional parameters/settings:

var dragresize = new DragResize('dragresize',

{ minWidth: 50, minHeight: 50, minLeft: 20, minTop: 20, maxLeft: 600, maxTop: 600 });

// Optional settings/properties of the DragResize object are:

// enabled: Toggle whether the object is active.

// handles[]: An array of drag handles to use (see the .JS file).

// minWidth, minHeight: Minimum size to which elements are resized (in pixels).

// minLeft, maxLeft, minTop, maxTop: Bounding box (in pixels).

// Next, you must define two functions, isElement and isHandle. These are passed

// a given DOM element, and must "return true" if the element in question is a

// draggable element or draggable handle. Here, I'm checking for the CSS classname

// of the elements, but you have have any combination of conditions you like:

dragresize.isElement = function(elm)

{

if (elm.className && elm.className.indexOf('drsElement') > -1) return true;

};

dragresize.isHandle = function(elm)

{

if (elm.className && elm.className.indexOf('drsMoveHandle') > -1) return true;

};

// You can define optional functions that are called as elements are dragged/resized.

// Some are passed true if the source event was a resize, or false if it's a drag.

// The focus/blur events are called as handles are added/removed from an object,

// and the others are called as users drag, move and release the object's handles.

// You might use these to examine the properties of the DragResize object to sync

// other page elements, etc.

dragresize.ondragfocus = function() { };

dragresize.ondragstart = function(isResize) { };

dragresize.ondragmove = function(isResize) { };

dragresize.ondragend = function(isResize) { };

dragresize.ondragblur = function() { };

// Finally, you must apply() your DragResize object to a DOM node; all children of this

// node will then be made draggable. Here, I'm applying to the entire document.

dragresize.apply(document);

Here's our draggable elements.

All that's required is that they have a relative or absolute CSS 'position',

Easy!

<p>This is a JavaScript library that lets you easily implement user-friendly

and customisable dragging and resizing of your page elements. You might want to

use it as part of a web application -- it contains all you need for a

lightweight "windowing" system. Features include:</p>

<ul>

<li><strong>Can both drag and resize</strong> page elements.</li>

<li><strong>Works with absolute and relatively positioned</strong> elements

 in your page.</li>

<li><strong>Customisable appearance</strong> as it makes extensive use of CSS

 classes for layout of its resisze handles.</li>

<li><strong>Unobtrusive, Object-Orientated JavaScript</strong> means it's easy

 to add to your pages.</li>

<li><strong>Bounding boxes and minimum sizes</strong> can be set and

 automatically enforced.</li>

<li><strong>Cross-browser compatible</strong> so it works for everyone.</li>

<li><strong>Small code size</strong> so your visitors don't have to wait!</li>

</ul>
