png图片ie6下不透明的解决方法
png图片ie6下不透明的解决方法<div class="postBody">在ie7+和ff下默认支持png的透明，ie6里面是没有透明效果的。查了几种方案，备忘
1、采用方案
<input name="image" type="image" style="filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/test.png',sizingMethod='crop'); "/>既：<style type="text/css"><!--.pngpic { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/pngpic.png',sizingMethod='crop'); }--></style> 2、备选
function fixPng() { var arVersion = navigator.appVersion.split("MSIE") var version = parseFloat(arVersion) if ((version &gt;= 5.5 &amp;&amp; version &lt; 7.0) &amp;&amp; (document.body.filters)) { for(var i=0; i<document.images.length;></document.images.length;> var img = document.images; var imgName = img.src.toUpperCase(); if (imgName.indexOf(".PNG") &gt; 0) { var width = img.width; var height = img.height; var sizingMethod = (img.className.toLowerCase().indexOf("scale") &gt;= 0)? "scale" : "image"; img.runtimeStyle.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='" + img.src.replace('%23', '%2523').replace("'", "%27") + "', sizingMethod='" + sizingMethod + "')"; img.src="images/blank.gif" mce_src="images/blank.gif"; img.width = width; img.height = height; } } } }
