比如我想加一个：<div id="google1"><div id="main1"><style type="text/css">body{background:#ccc;}.block{position:absolute;left:0;top:100px;border:1px solid #000;background:red;width:30px;height:30px;}#google{width:300px;height:300px;border:2px inset #fff;background:#fff;position:relative;overflow:hidden;}</style><div id="google"><div id="main" class="block"></div></div><script type="text/javascript">//<![CDATA[function Drag(title,body,range){var w=window,win=body||title,x,y,_left,_top,range=range||function(x){return x};title.style.cursor='move';title.onmousedown=function (e){e=e||event;x=e.clientX,y=e.clientY,_left=win.offsetLeft,_top=win.offsetTop;this.ondragstart=function(){return false};document.onmousemove=e_move;document.onmouseup=undrag};function e_move(e){e=e||event;var cl=range(_left+e.clientX-x,'x'),ct=range(_top+e.clientY-y,'y');win.style.left=cl+'px';win.style.top=ct+'px';w.getSelection?w.getSelection().removeAllRanges():document.selection.empty();};function undrag(){this.onmousemove=null};};function $(x){return typeof x=='string'?document.getElementById(x):x};var google=$("google"),main=$('main');var max={x:google.offsetWidth-main.offsetWidth-4,y:google.offsetHeight-main.offsetHeight-4}Drag(main,false,function(x,type){return Math.max(0,Math.min(max[type],x))})//]]></script>大家可以复制代码测试下，以上是一个拖动的效果，我想子啊一个页面弄2个3个。更多的这样的效果，大神帮下~~谢谢
