png透明图片,ie下的怪异模式,无法显示的解决方法
方法一:
.mypng是png透明图片的class
/* ie6 png */
.mypng img {
azimuth:expression(this.pngSet?this.pngSet=true:(
this.nodeName == "IMG" && this.src.toLowerCase().indexOf('.png')>-1?
(this.runtimeStyle.backgroundImage = "none",
this.runtimeStyle.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader
(src='" + this.src + "', sizingMethod='image')", this.src = "transparent.gif"):
(this.origBg = this.origBg? this.origBg :
this.currentStyle.backgroundImage.toString().replace('url("', '').replace('")', ''),
this.runtimeStyle.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='" +
this.origBg + "', sizingMethod='crop')", this.runtimeStyle.backgroundImage = "none")),
this.pngSet=true);
}
方法二:
调用js代码对全站png图片处理
<!--[if IE 6]>
<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>
