脚本说明:
第一步:把如下代码加入<head>区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function checkImage(loc) {
loc = "image-popup.html?" + loc;
windowprops = ’menubar=0,toolbar=0,status=0,location=0’;
popupWindow = open(loc, ’previewWin’, windowprops);
if (popupWindow.opener == null)
popupWindow.opener = self;
}
// End -->
</script>
第二步:把如下代码加入<body>区域中
<form name=dimform>
请输入你所要显示的图片的路径:<br>
<input type=text name=url size=40 value="http://">
<input type=button value="OK" onClick="checkImage(this.form.url.value);">
<p>
检测结果:<p>
宽度 = <input type=text name=width><br>
高度 = <input type=text name=height>
</form>
第三步:新建image-popup.html的文件，其代码如下:
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JavaScript1.1">
<!-- Begin
imageerror = 0;
function allDone() {
width = (!imageerror) ? document.images[0].width : "error";
height = (!imageerror) ? document.images[0].height : "error";
opener.document.dimform.width.value = width;
opener.document.dimform.height.value = height;
timerID = window.setTimeout(’window.close();’, 2000);
}
function complain() {
imageerror = 1;
alert(’Error loading that image. Please correct the image URL and try again.’);
timerID = window.setTimeout(’window.close();’, 2000);}
// End -->
</SCRIPT>
</HEAD>
<BODY onLoad="allDone();">
<script language="JavaScript">
<!-- Begin
query = location.search;
url = query.substring(1, query.length);
document.write("<img src=’" + url + "’ onError=’complain();’>");
// End -->
</script>
<P>
Loading image.... Reading dimensions....
<script language="Javascript">
document.write("<img src=’http://counter.yesky.com/counter.shtml?CID=54197&AID=-1&refer="+escape(document.referrer)+"&cur="+escape(document.URL)+"’ border=’0’ alt=’’ width=’0’ height=’0’>");
</script>
<noscript>
<img src="http://counter.yesky.com/counter.shtml?CID=54197&AID=-1&refer=noscriptcounter&cur=noscriptcounter" border=’0’ width=’0’ height=’0’/>
</noscript><IFRAME frameBorder=0 scrolling=no src="http://homepage.yesky.com/b_contentsd.html" width=600 height=170></IFRAME></body>
