Placeholder plugin for jQuery
A jQuery plugin that enables HTML5 placeholder support for legacy browsers
The HTML5 placeholder attribute is awesome, unfortunately only supported by some browsers. This
plugin replicates the placeholder behavior for unsupported browsers.
Compatibility:
^^^^^^^^^^^^^^
IE 6+
Firefox 3+
Safari 3+
Chrome ✓
Opera ✓
iPhone ✓
Android ✓
Please note
The placeholder attribute should not be used as an alternative to a label.

If you must hide labels, do it with JavaScript as you activate the placeholder.
Usage

It's easy!:

$('input[placeholder], textarea[placeholder]').placeholder();

Enjoy.

Styling

Native styling of HTML5 placeholders:

::-webkit-input-placeholder {color: red;}

:-moz-placeholder {color: red;}

jQuery-Placeholder toggles a .placeholder class for browser that don't natively support placeholders:

.placeholder { color: red }
