opener.show();

父窗体需要顶一个show() 方法

父面页代码：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD LEVEL1//EN"><html>  <head>    <title>html.html</title>    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="this is my page">    <meta http-equiv="content-type" content="text/html; charset=UTF-8">        <!--<link rel="stylesheet" type="text/css" href="./styles.css">-->  </head>    <body>   <div><button id="btn">open new page</button></div><script>window.onload=function(){var btn = document.getElementById("btn");btn.onclick = openPage;function openPage(){try {window.open('newpage.html');  }catch(e){alert(e);}//alert("ok");}}function show(){document.title=new Date();}</script>  </body></html>

newpage.html 代码需要打开的页面

<!DOCTYPE HTML PUBLIC "-//IETF//DTD LEVEL1//EN"><html>  <head>    <title>newpage.html</title>    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="this is my page">    <meta http-equiv="content-type" content="text/html; charset=UTF-8">        <!--<link rel="stylesheet" type="text/css" href="./styles.css">-->  </head>    <body>    <button id="btn" onclick="fun()">单击</button><script>function fun(){opener.show();}</script>  </body></html>
