js获取电脑分辨率的思路及操作

  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

  

复制代码 代码如下:

  <script>

  alert(screen.width+"*"+screen.height)

  </script>

  

复制代码 代码如下:

  <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

  

复制代码 代码如下:

  <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>
