Js to obtain the computer resolution of the idea and operation

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>
