// 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.ondragstart = function(isResize) { };

<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>
