Here I use DD_belatedPNG_0.0.8a-min.js to handle the png problem in IE6.
In this js file, there is a filter:
progid:DXImageTransform.Microsoft.AlphaImageLoader(src="img.jpg",sizingMethod="crop")
This will make the <a> and <input> unclickable.
这个会导致该区域的链接(<a>标签)和按钮(<input>)不能点击。
解决方法,the resolve :
Add the style to the <a> or <input>, 为链接或按钮添加style:
style="position: relative;"
