document.write('<table cellspacing=0 cellpadding=0 width=1 height='+hei+'>');  
for(i=0;i<cou;i++){document.write('<tr><td height='+d2+'><tr><td height='+d1+' bgcolor=333333>')}</script></table>

73、js翻页  
<script>document.write("<a href="+location.href.replace(/\.html/g,"_2.html")+">2</a>");</script>

 

网页可见区域宽：document.body.clientWidth; 

网页可见区域高：document.body.clientHeight; 

网页可见区域高：document.body.offsetWeight; 

网页可见区域高：document.body.offsetHeight; 

网页正文全文宽：document.body.scrollWidth; 

网页正文全文高：document.body.scrollHeight;
/* 在IE7下,当网页上有DTD验证的时候,是无法得到的.
** 解决办法:document.documentElement.clientHeight
*/

网页被卷去的高：document.body.scrollTop; 

网页被卷去的左：document.body.scrollLeft; 

网页正文部分上：window.screenTop; 

网页正文部分左：window.screenLeft; 

屏幕分辨率的高：window.screen.height; 

屏幕分辨率的宽：window.screen.width; 

屏幕可用工作区高度：window.screen.availHeight; 

屏幕可用工作区宽度：window.screen.availWidth;

JS获取DIV在BODY内的绝对坐标
function   getAbsPoint(e)     
{     
    var   x   =   e.offsetLeft,   y   =   e.offsetTop;     
    while(e=e.offsetParent)   
    {   
       x   +=   e.offsetLeft;     
       y   +=   e.offsetTop;  
    }   
    alert("x:"+x+","+"y:"+y);     
}  
 
方法2：  
 
function   getAbsPoint(obj)     
{     
   var   x,y;     
   oRect   =   obj.getBoundingClientRect();     
x=oRect.left     
y=oRect.top     
alert("("+x+","+y+")")     
}  
 
JS中获得窗口属性的方法   
 
1。获得屏幕的分辨率：   
screen.width   
screen.height   
 
2。获得窗口大小：   
document.body.clientWidth   
document.body.clientHeight   
 
3。获得窗口大小（包含Border、Scroll等元素）   
document.body.offsetWidth   
document.body.offsetHeight  

方法二

$.getAbsPos = function(pTarget){
                     pTarget = JObj.$(pTarget);
                    
                     if(!pTarget.getBoundingClientRect){
                            var x_ = y_ = 0;

                while(pTarget.offsetParent){
                        x_ += pTarget.offsetLeft;
                        y_ += pTarget.offsetTop;
                        pTarget = pTarget.offsetParent;
                }
                            x_ += pTarget.offsetLeft;
                            y_ += pTarget.offsetTop;
                            return {x:x_,y:y_}
                     }else{
                            var body = document.compatMode == 'CSS1Compat' ? document.documentElement : document.body;
                            var rect = pTarget.getBoundingClientRect()
                            return {x:rect.left + body.scrollLeft,y:rect.top + body.scrollTop};
                     }
              }
