javascript中从子窗口刷新父窗口

发布于 2024-09-24 01:17:35 字数 163 浏览 1 评论 0原文

我已经寻找了一段时间，找不到适合我需求的答案。我有一个页面弹出一个窗口（window.open），让用户登录（创建cookie，设置会话），然后重定向到另一个页面。当模态重定向时，我想刷新父页面，这样我刚刚做的所有好东西都会被父页面识别。我尝试过 window.opener 之类的东西。有人可以帮我一点吗？谢谢

弹出窗口中的 window.opener 将引用打开窗口的 window 对象，因此您当然应该能够调用 window.opener.location.reload();。只要您不违反同源策略，弹出窗口就可以调用脚本并进行操作父窗口对象上的属性就像父窗口中的代码一样。

这是一个实时示例，演示了子级回调父级上的函数，以及直接操作父级。下面引用了完整的代码。

但那个例子并没有完全按照你所说的做，所以我做了这个好吧，它让子级通过 window.opener.location.reload() 刷新父页面。

第一个实时示例的父代码：（

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Parent Window</title>
<!--[if IE]>
  <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<style>
  article, aside, figure, footer, header, hgroup, 
  menu, nav, section { display: block; }
</style>
</head>
<body>
  <input type='button' id='btnOpen' value='Open Window'>
  <div id='display'></div>
</body>
<script type='text/javascript'>
  (function() {
    var btnOpen = document.getElementById('btnOpen');
    btnOpen.onclick = btnOpenClick;

    function btnOpenClick() {
      window.open('http://jsbin.com/ehupo4/2');
    }

    // Make the callback function available on our
    // `window` object. I'm doing this explicitly
    // here because I prefer to export any globals
    // I'm going to create explicitly, but if you
    // just declare a function in a script block
    // and *not* inside another function, that will
    // automatically become a property of `window`
    window.callback = childCallback;
    function childCallback() {
      document.getElementById('display').innerHTML =
          'Got callback from child window at ' + new Date();
    }
  })();
</script>
</html>

您不必像上面那样使用作用域函数，但保留全局变量很有用。）

第一个实时示例的子代码：

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Child Window</title>
<!--[if IE]>
  <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<style>
  article, aside, figure, footer, header, hgroup, 
  menu, nav, section { display: block; }
</style>
</head>
<body>
  <p>I'm the child window</p>
</body>
<script type='text/javascript'>
  if (window.opener) {
    // Call the provided callback
    window.opener.callback();

    // Do something directly
    var p = window.opener.document.createElement('p');
    p.innerHTML = "I was added by the child directly.";
    window.opener.document.body.appendChild(p);
  }
</script>
</html>

window.opener in the popup will refer to the window object of the opening window, so of course you should be able to call window.opener.location.reload();. Provided you don't run afoul of the Same Origin Policy, the popup window can call scripts and manipulate properties on the parent window object just like code in the parent can.

Here's a live example demonstrating the child calling back to a function on the parent, and also manipulating the parent directly. The full code for this is quoted below.

But that example didn't do exactly what you said, so I've done this one as well, which has the child refreshing the parent page via window.opener.location.reload().

Parent code of first live example:

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Parent Window</title>
<!--[if IE]>
  <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<style>
  article, aside, figure, footer, header, hgroup, 
  menu, nav, section { display: block; }
</style>
</head>
<body>
  <input type='button' id='btnOpen' value='Open Window'>
  <div id='display'></div>
</body>
<script type='text/javascript'>
  (function() {
    var btnOpen = document.getElementById('btnOpen');
    btnOpen.onclick = btnOpenClick;

    function btnOpenClick() {
      window.open('http://jsbin.com/ehupo4/2');
    }

    // Make the callback function available on our
    // `window` object. I'm doing this explicitly
    // here because I prefer to export any globals
    // I'm going to create explicitly, but if you
    // just declare a function in a script block
    // and *not* inside another function, that will
    // automatically become a property of `window`
    window.callback = childCallback;
    function childCallback() {
      document.getElementById('display').innerHTML =
          'Got callback from child window at ' + new Date();
    }
  })();
</script>
</html>

(You don't have to use a scoping function as I did above, but it's useful to keep your globals contained.)

Child code of first live example:

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Child Window</title>
<!--[if IE]>
  <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<style>
  article, aside, figure, footer, header, hgroup, 
  menu, nav, section { display: block; }
</style>
</head>
<body>
  <p>I'm the child window</p>
</body>
<script type='text/javascript'>
  if (window.opener) {
    // Call the provided callback
    window.opener.callback();

    // Do something directly
    var p = window.opener.document.createElement('p');
    p.innerHTML = "I was added by the child directly.";
    window.opener.document.body.appendChild(p);
  }
</script>
</html>
