拾色器代码如下（color.js）：

// JavaScript Document
(function($){
$.fn.pickColor=function(callback)
{
var itemColors=["#FFFFFF","#E5E4E4","#D9D8D8","#C0BDBD","#A7A4A4","#8E8A8B","#827E7F","#767173","#5C585A","#000000","#FEFCDF","#FEF4C4","#FEED9B","#FEE573","#FFED43","#F6CC0B","#E0B800","#C9A601","#AD8E00","#8C7301","#FFDED3","#FFC4B0","#FF9D7D","#FF7A4E","#FF6600","#E95D00","#D15502","#BA4B01","#A44201","#8D3901","#FFD2D0","#FFBAB7","#FE9A95","#FF7A73","#FF483F","#FE2419","#F10B00","#D40A00","#940000","#6D201B","#FFDAED","#FFB7DC","#FFA1D1","#FF84C3","#FF57AC","#FD1289","#EC0078","#D6006D","#BB005F","#9B014F","#FCD6FE","#FBBCFF","#F9A1FE","#F784FE","#F564FE","#F546FF","#F328FF","#D801E5","#C001CB","#8F0197","#E2F0FE","#C7E2FE","#ADD5FE","#92C7FE","#6EB5FF","#48A2FF","#2690FE","#0162F4","#013ADD","#0021B0","#D3FDFF","#ACFAFD","#7CFAFF","#4AF7FE","#1DE6FE","#01DEFF","#00CDEC","#01B6DE","#00A0C2","#0084A0","#EDFFCF","#DFFEAA","#D1FD88","#BEFA5A","#A8F32A","#8FD80A","#79C101","#3FA701","#307F00","#156200","#D4C89F","#DAAD88","#C49578","#C2877E","#AC8295","#C0A5C4","#969AC2","#92B7D7","#80ADAF","#9CA53B"];
var $colorBox=$(document.createElement("div")).css({"width":"100px","height":"100px","position":"absolute","border":"1px solid #999999","line-height":"10px"});
$.each(itemColors,function(n,v)
{
var $item=$('<a href="" title="'+v+'"><img src="" width="10" height="10" border="0" style="background:'+v+';" /></a>').click(function(){callback(v);$colorBox.remove();return false;}).appendTo($colorBox);
})
$colorBox.insertAfter(this).hover(function(){},function(){$colorBox.remove();});
}
})(jQuery);

然后在页面上面调用，代码如下：

两种方式都可以：

（一）图片

<img src="images/20091110144913.gif"onclick="var $this=$(this);$this.pickColor(function(color){$this.css('background',color);});"/>

（二）文本框
<input type="text" size="7" maxlength="7" value="#ffffff"onclick="var $this=$(this);$this.pickColor(function(color){$this.css('background',color);$this.val(color);});"/>
