  </body>
<html>
<script type="text/javascript" src="jquery-1.4.4.js"></script>
<script>
//contentWindow这个属性，相当于获取iframe网页里面的window对象
$(function(){
  //父窗体获取子窗体的变量
  alert(document.getElementById("name_iframe").contentWindow.vname);//父窗体获取子窗体的方法
  document.getElementById("name_iframe").contentWindow.test();//父窗体获取子窗体的内容
  alert(document.getElementById("name_iframe").contentWindow.document.body.outerHTML);
});
var myname="hb";
function parentFunction(){
