    var win;
    function openChild(e)

      var evt = e || window.event;
      win = window.open("child.htm","_blank"); 
       setSelect();
      } 

    function setSelect()
    { 
    //判断窗口是否关闭
      if(!win.closed) 
      { 
       //win.document.readyState   判断画面是否加载完成  ie
       if(win.document.readyState=="complete")
       {
       var obj = win.document.getElementById("sel");
          var opt = win.document.createElement("OPTION");      
          opt.value="111";
          opt.text="222"; 
          if(navigator.appName=="Netscape")
