Javascript 取得网页高度，宽度全集合

<SCRIPT LANGUAGE="JavaScript">
var  s = "";
s += "\r\n网页可见区域宽："+ document.body.clientWidth;
s += "\r\n网页可见区域高："+ document.body.clientHeight;
s += "\r\n网页可见区域宽："+ document.body.offsetWidth  +" (包括边线的宽)";
s += "\r\n网页可见区域高："+ document.body.offsetHeight +" (包括边线的宽)";
s += "\r\n网页正文全文宽："+ document.body.scrollWidth;
s += "\r\n网页正文全文高："+ document.body.scrollHeight;
s += "\r\n网页被卷去的高："+ document.body.scrollTop;
s += "\r\n网页被卷去的左："+ document.body.scrollLeft;
s += "\r\n网页正文部分上："+ window.screenTop;
s += "\r\n网页正文部分左："+ window.screenLeft;
s += "\r\n屏幕分辨率的高："+ window.screen.height;
s += "\r\n屏幕分辨率的宽："+ window.screen.width;
s += "\r\n屏幕可用工作区高度："+ window.screen.availHeight;
s += "\r\n屏幕可用工作区宽度："+ window.screen.availWidth;
alert(s);
</SCRIPT>

面向对象的JS写法

<script language="JavaScript" type="text/javascript">
<!--
function class1(){ 
　var pp=" this is a private property"; //私有属性成员pp 
　function pm(){ //私有方法成员pm，显示pp的值 
　　alert(pp); 
　} 
　this.method1=function(){ 
　　//在公有成员中改变私有属性的值 
　　pp="pp has been changed"; 
　} 
　this.method2=function(){ 
　　pm(); //在公有成员中调用私有方法 
　} 
} 
var obj1=new class1(); 
obj1.method1();  //调用公有方法method1 
obj1.method2();  //调用公有方法method2 
//-->
</script>
