jQuery plugin LazyForm Version 1 (zhangpeng chen)
定制您的CheckBox, Radio, Select。
在下面浏览器下测试通过:Firefox, IE7, IE8, Google浏览器。 (IE6还是算了吧),其它浏览器还没试过。

目前刚添加了4个皮肤,添加新皮肤非常方便,您可以参考已添加的皮肤图片和css代码,相信您会很快搞定。

效果截图:
一、在没有使用LazyForm的情况下,在XP下运行截图如下

二、使用LazyForm(皮肤Blue)效果如下

三、使用LazyForm(皮肤Black)效果如下

四、皮肤Default

五、皮肤Gray


demo.html代码如下:

从代码你就可以看到,LazyForm没有动您的Html和Css样式一根汗毛。
想让Select变长,设置个长度就可以了。
把LazyForm.js去掉,就是您的原样。没有任何改变。
