在做页面时，用户要求，不同的分辨率，弹出窗口的位置不同
我想是不是先获得屏幕宽度，然后付值给变量，再在onclick中设置参数

<script>   
alert(screen.width+"*"+screen.height)   
</script>

<script>   
function  centerWindow(url,w,h){   
l=(screen.width-w)/2   
t=(screen.height-h)/2   
window.open(url,’’,’left=’+l+’,top=’+t+’,width=’+w+’,height=’+h)   
}   
</script>   
<input  type=button  onclick="centerWindow(’about:blank’,200,200)">   
---------------------------------------------------------------   
  
<body>   
<SCRIPT  LANGUAGE="JavaScript">   
var    s  ="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>   
---------------------------------------------------------------   
  
<SCRIPT  LANGUAGE="JavaScript">   
<!--  Begin   
function  redirectPage()  {   
/*var  url640x480  =  "http://www.yourweb.com/640x480.html";**记得改相应的页面*/   
var  url800x600  =  "index1.asp";   
var  url1024x768  =  "index2.asp";   
/*if  ((screen.width  ==  640)  &&  (screen.height  ==  480))   
window.location.href=  url640x480;*/   
 if  (screen.width  <=  800  )   
window.location.href=  url800x600;   
else  if  ((screen.width  >=  1024)  )   
window.location.href=  url1024x768;   
}   
//  End  -->   
</script>

这段代码是根据不同的屏幕显示不同的页面

下面是传递这个参数的

<script  language=JavaScript>   
document.write("<a href=’WebStat/index.asp’>");   
document.write("<img src=’WebStat/count.asp?Referer=<%=refer%> 
&Width="+escape(screen.width)+"&Height="+escape(screen.height)+ 
"’ border=0 width=1 height=1>");   
document.write("</a>");   
</script>
