placeholder.js — bring HTML 5 placeholder attribute to all browsers
placeholder.js is not maintained any more. Use one of those:
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();
placeholder.js (pure JS version)
JS: inputPlaceholder(document.getElementById('some_input'), "#AAA")
Limitations
placeholder.js doesn't work with <input type='password'> in IE (at least in IE ≤ 9).
