When making a page, the user requires different resolutions and different positions of the popup window. I wonder if I can get the screen width first, then pay the value to the variable, and then set the parameters in onclick

 
<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 =" Page visible area width: "+ document.body.clientWidth; 
s+="rn High visibility area: "+ document.body.clientHeight; 
s += "rn Full text width: "+ document.body.scrollWidth; 
s += "rn Full text of the web page: "+ document.body.scrollHeight; 
s += "rn On the body of the page: "+ window.screenTop; 
s += "rn Page body part left: "+ window.screenLeft; 
s += "rn High screen resolution: "+ window.screen.height; 
s += "rn Width of screen resolution: "+ window.screen.width; 
s +="rn Screen available workspace height: "+ window.screen.availHeight; 
s +="rn Screen available workspace width: "+ window.screen.availWidth; 
alert(s); 
</SCRIPT> 
--------------------------------------------------------------- 

<SCRIPT LANGUAGE="JavaScript"> 
<!-- Begin 
function redirectPage() { 
/*var url640x480 = "http://www.yourweb.com/640x480.html";** Remember to change the page accordingly */ 
var url800x600 = "index1.asp"; 
var url1024x768 = "index2.asp"; 
 
if (screen.width <= 800 ) 
window.location.href= url800x600; 
else if ((screen.width >= 1024) ) 
window.location.href= url1024x768; 
} 
// End --> 
</script>

This code displays different pages on different screens

Here's what passes this parameter

 
<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>
