IE6不支持PNG半透明图片的缺陷为web设计带来了极大的不便,之前曾经介绍过用滤镜+hack的方法实现显示PNG,不过实现起来相当繁琐。还有一种网上比较流行的方法,更加简便,下面详细介绍这种方法:
把以下代码保存为correctpng.js
function correctPNG() { for(var i=0; i<document.images.length; i++) { var img = document.images[i] var imgName = img.src.toUpperCase() if (imgName.substring(imgName.length-3, imgName.length) == "PNG") { var imgID = (img.id) ? "id='" + img.id + "' " : "" var imgClass = (img.className) ? "class='" + img.className + "' " : "" var imgTitle = (img.title) ? "title='" + img.title + "' " : "title='" + img.alt + "' " var imgStyle = "display:inline-block;" + img.style.cssText if (img.align == "left") imgStyle = "float:left;" + imgStyle if (img.align == "right") imgStyle = "float:right;" + imgStyle if (img.parentElement.href) imgStyle = "cursor:hand;" + imgStyle var strNewHTML = "<span " + imgID + imgClass + imgTitle + " style=\"" + "width:" + img.width + "px; height:" + img.height + "px;" + imgStyle + ";" + "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader" + "(src=\'" + img.src + "\', sizingMethod='scale');\"></span>" img.outerHTML = strNewHTML i = i-1 }; }; };
if(navigator.userAgent.indexOf("MSIE")>-1) { window.attachEvent("onload", correctPNG); };
在网页的头部引用一下
<SCRIPT language=JavaScript src="correctpng.js" type=text/javascript></SCRIPT>
使用的时候直接用img标签即可。
