<h1 class="title">Farbtastic: jQuery color picker plug-in</h1>
<div class="content"><p>Farbtastic is a <a href="http://www.jquery.com/">jQuery</a> plug-in that can add one or more color picker widgets into a page. Each widget is then linked to an existing element (e.g. a text field) and will update the element's value when a color is selected.</p>
<p>Farbtastic uses layered transparent PNGs to render a saturation/luminance gradient inside of a hue circle. No Flash or pixel-sized divs are used.</p>
<p>Farbtastic was written by <a href="http://www.acko.net/dev/farbtastic">Steven Wittens</a> and is licensed under the GPL.</p>
<h2>Basic Usage</h2>
<ol>
<li>Include farbtastic.js and farbtastic.css in your HTML:<br />
<div class="codeblock"><code><script type="text/javascript" src="farbtastic.js"></script><br /><link rel="stylesheet" href="farbtastic.css" type="text/css" /></code></div>
</li>
<li>Add a placeholder div and a text field to your HTML, and give each an ID:<br />
<div class="codeblock"><code><form><input type="text" id="color" name="color" value="#123456" /></form><br /><div id="colorpicker"></div></code></div>
</li>
<li>Add a ready() handler to the document which initializes the color picker and link it to the text field with the following syntax:<br />
<div class="codeblock"><code><script type="text/javascript"><br /> $(document).ready(function() {<br /> $('#colorpicker').farbtastic('#color');<br /> });<br /></script></code></div>
</li>
</ol>
<p>See demo1.html and demo2.html for an example (jquery.js is not included!).</p>
<h2>Styling</h2>
<p>The color picker is a block-level element and is 195x195 pixels large. You can control the position by styling your placeholder (e.g. floating it).</p>
<p>Note that the black/white gradients inside wheel.png and mask.png were generated programmatically and cannot be recreated easily in an image editing program.</p>
<h2>Advanced Usage</h2>
<h3>jQuery Method</h3>
<dl>
<dt>$(...).farbtastic()<br />
$(...).farbtastic(callback)</dt>
<dd>This creates color pickers in the selected objects. <code>callback</code> is optional and can be a:</p>
<ul>
<li><em>DOM Node</em>, <em>jQuery object</em> or <em>jQuery selector</em>: the color picker will be linked to the selected element(s) by syncing the value (for form elements) and color (all elements).</li>
<li><em>Function</em>: this function will be called whenever the user chooses a different color.</dd>
</dl>
<h3>Object</h3>
<dl>
<dt>$.farbtastic(placeholder)<br />
$.farbtastic(placeholder, callback)<br />
</dt>
<dd>Invoking <code>$.farbtastic(placeholder)</code> is the same as using <code>$(placeholder).farbtastic()</code> except that the Farbtastic object is returned instead of the jQuery object. This allows you to use the Farbtastic methods and properties below.</p>
<p>Note that there is only one Farbtastic object per placeholder. If you call <code>$.farbtastic(placeholder)</code> twice <em>with the same placeholder</em>, you will get the same object back each time.</p>
<p>The optional <code>callback</code> argument behaves exactly as for the jQuery method.<br />
</dd>

<h3>Methods</h3>

<dt>.setColor(string)</dt>
<dd>Sets the picker color to the given color in hex representation.</dd>
<dt>.setColor([h, s, l])</dt>
<dd>Sets the picker color to the given color in normalized HSL (0..1 scale).</dd>
</dl>
<h3>Properties</h3>
<dl>
<dt>.linked</dt>
<dd>The elements (jQuery object) or callback function this picker is linked to.</dd>
<dt>.color</dt>
<dd>Current color in hex representation.</dd>
<dt>.hsl</dt>
<dd>Current color in normalized HSL.</dd>
