屏幕坐标,鼠标坐标,屏幕宽度等取值方式

window.event.x: window.event.x
window.event.y: window.event.y
event.clientX: event.clientX
event.clientY: event.clientY
event.offsetX: event.offsetX
event.offsetY: event.offsetY
window.event.screenX: window.event.screenX
window.event.screenY: window.event.screenY 

打个标记,用到好几次了,下次免得再去google

<script. language="javascript">
function screenInfo(){
    var  s = "";
   s += "/r/n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网页可见区域宽："+ document.body.offsetWidth  +" (包括边线的宽)";
   s += "/r/n网页可见区域高："+ document.body.offsetHeight +" (包括边线的宽)";

   s += "/r/n网页正文全文高："+ document.body.scrollHeight;
   s += "/r/n网页被卷去的高："+ document.body.scrollTop;
   s += "/r/n网页被卷去的左："+ document.body.scrollLeft;
   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;
