用JS解决IE6下透明png图片失效方法

不需要改任何东西,只需在页面里包含此段代码.png图片使用就如使用jpg图片一样简单,而且只有在IE6下才会运行些效果代码.

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.appName == "Microsoft Internet Explorer") 
	{ 
	if(navigator.appVersion.match(/6./i)=='6.') 
	{ 
	window.attachEvent("onload",correctPNG);
	}else{} 
}
