制作方法一：加入JS代码

1、在页面的<head></head>中加入JS代码：

<script language="javascript">

var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {

d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}

if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];

for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=locateObject(n,d.layers[i].document); return x;

}
