低版本IE支持透明png格式图片的方法。
在这里下载 pngfix.js ，在页面head加入
| <!--[if lt IE 7.]> <script defer type="text/javascript" src="pngfix.js"></script> <![endif]--> |
单页面可以直接加入
| <!--[if lt IE 7]> <script language="JavaScript"> function correctPNG() // correctly handle PNG transparency in Win IE 5.5 & 6. { var arVersion = navigator.appVersion.split("MSIE") var version = parseFloat(arVersion[1]) if ((version >= 5.5) && (document.body.filters)) { for(var j=0; j<document.images.length; j++) { var img = document.images[j] var imgName = img.src.toUpperCase() if (imgName.substring(imgName.length-3, imgName.length) == "PNG") { var imgID = (img.id) ?
