js 调用父窗口的方法

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>
