javascript去掉图片的背景颜色

在实现页面效果时候，经常会遇到图片间的叠加，但是简单的叠加的话，上面的图片底色还是会显示出来，即使在做的时候改为透明底色。这时候就要通过代码filter来实现了。具体如下：遍历所有的图片改为透明背景色。

 <mce:script language="javascript"><!-- function correctPNG() { for(var i=0; i<; i++) { var img = [i] var imgName = () if ((-3, ) == "PNG") { var imgID = () ? "id='" + + "' " : "" var imgClass = () ? "class='" + + "' " : "" var imgTitle = () ? "title='" + + "' " : "title='" + + "' " var imgStyle = "display:inline-block;" + if ( == "left") imgStyle = "float:left;" + imgStyle if ( == "right") imgStyle = "float:right;" + imgStyle if () imgStyle = "cursor:hand;" + imgStyle var strNewHTML = "<span " + imgID + imgClass + imgTitle + " style="/" mce_style="/""" + "width:" + + "px; height:" + + "px;" + imgStyle + ";" + "filter:progid:" + "(src=/'" + + "/', sizingMethod='scale');/"></span>" = strNewHTML i = i-1 } } } ("onload", correctPNG); // --></mce:script>
