首先看我们的标签代码：
我们将利用IE中特有的特效来满足这个要求，这就是AlphaImageLoader Filter (http://msdn.microsoft.com/library/default.asp?url=/workshop/author/filter/reference/filters/alphaimageloader.asp)
如何做？
将下面代码保存为correctPNG.js:
复制代码 代码如下:
function correctPNG()
{
for(var i=0; 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 = "+ " style="" + "width:" + img.width + "px; margin:6px; height:" + img.height + "px;" + imgStyle + ";"
+ "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader"
+ "(src='" + img.src + "', sizingMethod='scale');">"
img.outerHTML = strNewHTML
i = i-1
}
}
}
window.attachEvent("onload", correctPNG);
然后在你需要透明的网页中的....区加入：
在区加入多个与类似的PNG图片，试试看？
另一种方法：
复制代码 代码如下:
.pngholder{
width:100px;
height:100px;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='https://www.jb51.net/attachments/200510/03_124401_ie.png');
}
.pngalpha{
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=0);
background:url(https://www.jb51.net/attachments/200510/03_124401_ie.png) no-repeat;
width:100px;
height:100px;
}
透明
不透明
