本文介绍了一个基于jQuery的JavaScript拾色器插件，该插件通过创建一个包含多种颜色选项的弹出框来帮助用户选择颜色。适用于图片和文本框元素，并提供了详细的实现代码。

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);});" />
