|

|
// 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

Here's our draggable elements.

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

and are matched by the isElement/isHandle methods of a DragResize object.

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>
