HTML5 Placeholder jQuery Plugin

Demo & Examples

http://mathiasbynens.be/demo/placeholder

Example Usage

HTML

<input type="text" name="name" placeholder="e.g. John Doe">
<input type="email" name="email" placeholder="e.g. address@example.ext">
<input type="url" name="url" placeholder="e.g. http://mathiasbynens.be/">
<input type="tel" name="tel" placeholder="e.g. +32 472 77 69 88">
<input type="password" name="password" placeholder="e.g. h4x0rpr00fz">
<input type="search" name="search" placeholder="Search this site…">
<textarea name="message" placeholder="Your message goes here"></textarea>

jQuery

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

CSS

The plugin automatically adds class="placeholder" to the elements who are currently showing their placeholder text. You can use this to style placeholder text differently:

input, textarea { color: #000; }
.placeholder { color: #aaa; }

Notes

Works in all A-grade browsers, including IE6.
Automatically checks if the browser natively supports the HTML5 placeholder attribute for input and textarea elements. If this is the case, the plugin won’t do anything. If @placeholder is only supported for input elements, the plugin will leave those alone and apply to textareas exclusively. (This is the case for Safari 4, Opera 11.00, and possibly other browsers.)
Caches the results of its two feature tests in jQuery.fn.placeholder.input and jQuery.fn.placeholder.placeholder. For example, if @placeholder is natively supported for input elements, jQuery.fn.placeholder.input will be true. After loading the plugin, you can re-use these properties in your own code.
Makes sure it never causes duplicate IDs in your DOM, even in browsers that need an extra input element to fake @placeholder for password inputs. This means you can safely do stuff like:
```
<label for="bar">Example label</label>
<input type="password" placeholder="foo" id="bar">
```
And the <label> will always point to the <input> element you’d expect. Also, all CSS styles based on the ID will just work™.

This plugin is dual licensed under the MIT and GPL licenses, just like jQuery itself.
