图片切换:
程序代码<select name="selectface" onchange="cssrain(options[selectedIndex].value);">
<script>
for(i=1;i<12;i++)
{
document.write("<option value=http://www.makewing.com/lanren/emotions/07/"+i+".gif>头像"+i+"</option>");
}
</script>
</select>
<img id="face" src="http://www.makewing.com/lanren/emotions/07/1.gif">
<SCRIPT LANGUAGE="JavaScript">
function cssrain(obj)
{
document.getElementById("face").src=obj;
}
</SCRIPT>
<script>
for(i=1;i<12;i++)
{
document.write("<option value=http://www.makewing.com/lanren/emotions/07/"+i+".gif>头像"+i+"</option>");
}
</script>
</select>
<img id="face" src="http://www.makewing.com/lanren/emotions/07/1.gif">
<SCRIPT LANGUAGE="JavaScript">
function cssrain(obj)
{
document.getElementById("face").src=obj;
}
</SCRIPT>
随即背景:
程序代码<Script Language="JavaScript">
image = new Array(2); //定义image为图片数量的数组
image [0] = 'http://www.cssrain.cn/skins/tim/logo-jq.gif' //背景图象的路径
image [1] = 'http://www.cssrain.cn/demo/JQuery+API/logo-json.gif'
image [2] = 'http://www.cssrain.cn/skins/tim/isll_t.gif'
number = Math.floor(Math.random() * image.length);
document.write("<BODY BACKGROUND="+image[number]+">");
</Script>
image = new Array(2); //定义image为图片数量的数组
image [0] = 'http://www.cssrain.cn/skins/tim/logo-jq.gif' //背景图象的路径
image [1] = 'http://www.cssrain.cn/demo/JQuery+API/logo-json.gif'
image [2] = 'http://www.cssrain.cn/skins/tim/isll_t.gif'
number = Math.floor(Math.random() * image.length);
document.write("<BODY BACKGROUND="+image[number]+">");
</Script>
网页最后修改时间:
程序代码<script language="LiveScript">
<!-- Hiding
today = new Date()
document.write("现 在 时 间 是： ",today.getHours(),":",today.getMinutes())
document.write("<br>今 天 日 期 为： ", today.getMonth()+1,"/",today.getDate(),"/",today.getYear());
// end hiding contents -->
</script>
<html>
<body>
This is a simple HTML- page.

Last changes:
<script language="LiveScript">

document.write(document.lastModified)

获取上传文件的大小:
程序代码<html>
<input type="file" name="uploadfiles" onchange="ShowSize(this.value)"> <span id="rain"></span>
<script language="JavaScript">
<!--
/**
* obj 创建文件对象
* FilesObj 得到文件所上传的文件对像
* mySize 被上传文件的大小
*/
function ShowSize(files)
{
var obj,FilesObj ;
obj = new ActiveXObject("Scripting.FileSystemObject");
FilesObj = obj.GetFile(files);
var mySize = FilesObj .size/(1024*1024);
document.getElementById("rain").innerHTML=mySize+" M ";
}
//-->
</script>
</html>
<input type="file" name="uploadfiles" onchange="ShowSize(this.value)"> <span id="rain"></span>
<script language="JavaScript">
<!--
/**

*/
function ShowSize(files)
{
var obj,FilesObj ;
obj = new ActiveXObject("Scripting.FileSystemObject");
FilesObj = obj.GetFile(files);
var mySize = FilesObj .size/(1024*1024);
document.getElementById("rain").innerHTML=mySize+" M ";
