68、无法最小化的窗口
<body onblur='self.focus();'>

69、链接点外部css文件
<style>@import url("ie.css");</style>

70、内嵌式框架-网页中调用另外网页：
<object type="text/x-scriptlet" width="600" height="1000" data="http://www.winliuxq.com/"></object>

71、刷新改变窗口大小
<OBJECT classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11" onreadystatechange="if (this.readyState==4) this.Click();" VIEWASTEXT><PARAM name="Command" value="Maximize"></OBJECT>

72、JavaScript实现网页竖虚线
<script>hei=120;d1=2;d2=2;cou=Math.floor(hei/(d1+d2));
document.write('<table cellspacing=0 cellpadding=0 width=1 height='+hei+'>');
for(i=0;i<cou;i++){document.write('<tr><td height='+d2+'><tr><td height='+d1+' bgcolor=333333>')}</script></table>

73、js翻页
<script>document.write("<a href="+location.href.replace(/\.html/g,"_2.html")+">2</a>");</script>

网页可见区域宽：document.body.clientWidth;

网页可见区域高：document.body.clientHeight;

网页可见区域高：document.body.offsetWeight;

网页可见区域高：document.body.offsetHeight;

网页正文全文宽：document.body.scrollWidth;

网页正文全文高：document.body.scrollHeight;
/* 在IE7下,当网页上有DTD验证的时候,是无法得到的.
** 解决办法:document.documentElement.clientHeight
*/

网页被卷去的高：document.body.scrollTop;

网页被卷去的左：document.body.scrollLeft;

网页正文部分上：window.screenTop;

网页正文部分左：window.screenLeft;

屏幕分辨率的高：window.screen.height;

屏幕分辨率的宽：window.screen.width;

屏幕可用工作区高度：window.screen.availHeight;

屏幕可用工作区宽度：window.screen.availWidth;

JS获取DIV在BODY内的绝对坐标
function   getAbsPoint(e)
{
    var   x   =   e.offsetLeft,   y   =   e.offsetTop;
    while(e=e.offsetParent)
    {
       x   +=   e.offsetLeft;
       y   +=   e.offsetTop;
    }
    alert("x:"+x+","+"y:"+y);
}

方法2：

function   getAbsPoint(obj)
{
   var   x,y;
   oRect   =   obj.getBoundingClientRect();
x=oRect.left
y=oRect.top
alert("("+x+","+y+")")
}

JS中获得窗口属性的方法

1。获得屏幕的分辨率：
screen.width
screen.height

2。获得窗口大小：
document.body.clientWidth
document.body.clientHeight

3。获得窗口大小（包含Border、Scroll等元素）
document.body.offsetWidth
document.body.offsetHeight

方法二

$.getAbsPos = function(pTarget){
                     pTarget = JObj.$(pTarget);

                     if(!pTarget.getBoundingClientRect){
                            var x_ = y_ = 0;

                while(pTarget.offsetParent){
                        x_ += pTarget.offsetLeft;
                        y_ += pTarget.offsetTop;
                        pTarget = pTarget.offsetParent;
                }
                            x_ += pTarget.offsetLeft;
                            y_ += pTarget.offsetTop;
                            return {x:x_,y:y_}
                     }else{
                            var body = document.compatMode == 'CSS1Compat' ? document.documentElement : document.body;
                            var rect = pTarget.getBoundingClientRect()
                            return {x:rect.left + body.scrollLeft,y:rect.top + body.scrollTop};
                     }
              }

js.html 可在直接使用
