页面自动缩小

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<script  type="text/javascript">
function resizeWin(maxX,maxY,speed,delay,win){
	this.obj = "resizeWin" + (resizeWin.count++);
	eval(this.obj + "=this");
	if (!win)     this.win = self;    else this.win = eval(win);
	if (!maxX)    this.maxX = 400;    else this.maxX = maxX;
	if (!maxY)    this.maxY = 300;    else this.maxY = maxY;
	if (!speed)   this.speed = 1/7;   else this.speed = 1/speed;
	if (!delay)   this.delay = 30;    else this.delay = delay;
	this.doResize = (document.all || document.getElementById);
	this.stayCentered = false;
	
	this.initWin = 	function(){
		if (this.doResize){
			this.resizeMe();
			}
		else {
			this.win.resizeTo(this.maxX + 10, this.maxY - 20);
			}
		}

this.resizeMe = function(){
		this.win.focus();
		this.updateMe();
		}
	
	this.resizeTo = function(x,y){
		this.maxX = x;
		this.maxY = y;
		this.resizeMe();
		}
		
	this.stayCentered = function(){
		this.stayCentered = true;
		}

this.updateMe = function(){
		this.resizing = true;
		var x = Math.ceil((this.maxX - this.getX()) * this.speed);
		var y = Math.ceil((this.maxY - this.getY()) * this.speed);
		if (x == 0 && this.getX() != this.maxX) {
			if (this.getX() > this.maxX) x = -1;
			else  x = 1;
			}
		if (y == 0 && this.getY() != this.maxY){
			if (this.getY() > this.maxY) y = -1;
			else y = 1;
			}
		if (x == 0 && y == 0) {
			this.resizing = false;
    		}
		else {
			this.win.top.resizeBy(parseInt(x),parseInt(y));
			if (this.stayCentered == true) this.win.moveTo((screen.width - this.getX()) / 2,(screen.height - this.getY()) / 2);
			setTimeout(this.obj + '.updateMe()',this.delay)
			}
		}
		
	this.write =  function(text){
		if (document.all && this.win.document.all["coords"]) this.win.document.all["coords"].innerHTML = text;
		else if (document.getElementById && this.win.document.getElementById("coords")) this.win.document.getElementById("coords").innerHTML = text;
		}
		
	this.getX =  function(){
		if (document.all) return (this.win.top.document.body.clientWidth + 10)
		else if (document.getElementById)
			return this.win.top.outerWidth;
		else return this.win.top.outerWidth - 12;
	}
	
	this.getY = function(){
		if (document.all) return (this.win.top.document.body.clientHeight + 29)
		else if (document.getElementById)
			return this.win.top.outerHeight;
		else return this.win.top.outerHeight - 31; 
	}
	
	this.onResize =  function(){
		if (this.doResize){
			if (!this.resizing) this.resizeMe();
			}
		}

return this;
}
resizeWin.count = 0;

</script>
<script type="text/javascript">

</script>

第二步：把<body>中的内容改为：
<body onLoad="booyah.initWin()" onResize="booyah.onResize()">
