一、png图片写在css中作为背景图(IE5.5+ 的 AlphaImageLoader 滤镜功能)
- <style>
- .png{
- border:1px solid #360;
- width:905px;
- height:545px;
- background: url(yun.png) no-repeat;
- _filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled='true', sizingMethod='scale', src="yun.png");
- _background:none;
- }
- </style>
- <div class="png"></div>
二、png图片写在html中作为插入图(一般使用js实现)
方法一:
- <!--[if IE 6]>
- <script>
- function correctPNG(){
- for(var i=0; i<document.p_w_picpaths.length; i++){
- var img = document.p_w_picpaths[i];
- var imgimgName = 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;
- ii = i-1;
- }
- }
- }
- window.attachEvent("onload", correctPNG);
- </script>
- <![endif]-->
- <img src="yun.png" border="0" />
方法二:(注:需要在图片处调用js)
- <script language="javascript">
- // 修复 IE 下 PNG 图片不能透明显示的问题
- function fixPNG(myImage) {
- var arVersion = navigator.appVersion.split("MSIE");
- var version = parseFloat(arVersion[1]);
- if ((version >= 5.5) && (version < 7) && (document.body.filters)){
- var imgID = (myImage.id) ? "id='" + myImage.id + "' " : "";
- var imgClass = (myImage.className) ? "class='" + myImage.className + "' " : "";
- var imgTitle = (myImage.title) ? "title='" + myImage.title + "' " : "title='" + myImage.alt + "' ";
- var imgStyle = "display:inline-block;" + myImage.style.cssText;
- var strNewHTML = "<span " + imgID + imgClass + imgTitle
- + " style=\"" + "width:" + myImage.width
- + "px; height:" + myImage.height
- + "px;" + imgStyle + ";"
- + "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader"
- + "(src=\'" + myImage.src + "\', sizingMethod='scale');\"></span>";
- myImage.outerHTML = strNewHTML;
- } }
- window.onload=function(){
- document.getElementById("top").style.height=screen.height/5+"px";
- }
- </script>
- <img src="logo.png" border="0" onload="fixPNG(this)" />
