• 自制了一个JQUERY 颜色选择器插件!!!


    a 上图:


    调用方法:
    首先引入相关js
    <script type="text/javascript" src="http://www.google.cn/jsapi"></script>
    <script type="text/javascript">google.load("jquery""1.3.2");</script>
    <script type="text/javascript" src="jQuery.ColorPicker.js"></script>
    然后编写你的代码:
    <script type="text/javascript">
        $(
    function(){
            $.showcolor(
    'btncolor','txtcolor');//第一参数:按钮ID,第二参数: 文本框ID
            $.showcolor(
    'imgcolor','txtcolor1');
        })
    </script>

    jquery.colorpicker.js 代码如下:
