placeholder.js — bring HTML 5 placeholder attribute to all browsers

The placeholder attribute is the part of HTML5 specification. Currently, it works only in WebKit-based browsers, like Google Chrome and Safari. Placeholder.js fixes it!

Tested on IE 6—8, Firefox 3.5, Safari 4—5, Google Chrome 3—6, Opera 9.5—10.6.

jquery.textPlaceholder.js

CSS: .text-placeholder {color: #AAA !important}
JS: $("[placeholder]").textPlaceholder();

An example.

placeholder.js (pure JS version)

JS: inputPlaceholder(document.getElementById('some_input'), "#AAA")

An example.

Limitations

placeholder.js doesn't work for <input type='password'> in IE (at least in IE ≤ 9). If you need it use danielstocks/jQuery-Placeholder instead.
