Basic Usage

Include farbtastic.js and farbtastic.css in your HTML: <script type="text/javascript" src="farbtastic.js"></script>

<link rel="stylesheet" href="farbtastic.css" type="text/css" /> Add a placeholder div and a text field to your HTML, and give each an ID: <form><input type="text" id="color" name="color" value="#123456" /></form>

<div id="colorpicker"></div>

Add a ready() handler to the document which initializes the color picker and link it to the text field with the following syntax: <script type="text/javascript">

$(document).ready(function() {

$('#colorpicker').farbtastic('#color');

});

</script>



See demo1.html and demo2.html for an example (jquery.js is not included!).

Styling

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).

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.

Advanced Usage

jQuery Method

$(...).farbtastic() $(...).farbtastic(callback) This creates color pickers in the selected objects. callback is optional and can be a: DOM Node, jQuery object or jQuery selector: the color picker will be linked to the selected element(s) by syncing the value (for form elements) and color (all elements).

Function: this function will be called whenever the user chooses a different color. It should have the following signature: function callback(color) { ... } With color the chosen color in hex representation (e.g. '#123456').

Object

$.farbtastic(placeholder) $.farbtastic(placeholder, callback) Invoking $.farbtastic(placeholder) is the same as using $(placeholder).farbtastic() except that the Farbtastic object is returned instead of the jQuery object. This allows you to use the Farbtastic methods and properties below. Note that there is only one Farbtastic object per placeholder. If you call $.farbtastic(placeholder) twice with the same placeholder, you will get the same object back each time. The optional callback argument behaves exactly as for the jQuery method.

Methods

.linkTo(callback) Allows you to set a new callback. Any existing callbacks are removed. See above for the meaning of callback . .setColor(string) Sets the picker color to the given color in hex representation (e.g. '#123456'). .setColor([h, s, l]) Sets the picker color to the given color in normalized HSL (0..1 scale).
