Answer 1

<script>
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>
插入到你做的html中在head之间插入！
