window.open() 父子页面的传参&传值问题

window.open() 传参问题： 
父页面中： 

 window.open('url', '', 'resizable=1, menuBar=0, toolBar=0, scrollbars=yes, Status=yes, resizable=1');

url页面拿父页面的xx元素赋值 

 opener.document.getElementById("xx").value="newValue";

 if(window.opener){//判断是否有父窗口,即打开本页面的窗口
     window.opener.location.reload();//刷新父窗口
     window.opener.close();  //关闭父窗口
 }

window.open() 传值问题（参考：http://www.cnblogs.com/gavindou/archive/2008/04/09/1143858.html）： 
a.html(父) 
注意：window.open("b.html","","modal=yes,width=500,height=500,resizable=no,scrollbars=no"); 中的第3个参数一定要有  modal=yes
