把这个插在需要的网页里

程序代码

<!--[if lt IE 7]>

<![endif]-->

以下存为11111111.js调用

程序代码

var arVersion = navigator.appVersion.split("MSIE")

var version = parseFloat(arVersion[1])

if ((version >= 5.5) && (document.body.filters))

{

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');\">"

img.outerHTML = strNewHTML

i = i-1

}

</document>

也可以直接把下面这段代码放到<head>内:

程序代码

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

}

window.attachEvent("onload", correctPNG);

</script>
