关闭iframe跨域

Question

I am trying to do something similar to the Clipper application here http://www.polyvore.com/cgi/clipper 我想在这里做一些类似于Clipper应用程序的东西http://www.polyvore.com/cgi/clipper

I can make the iframe appear in another website (cross domain). 我可以让iframe出现在另一个网站（跨域）中。 But I cannot make the "close" button to work. 但我无法使“关闭”按钮起作用。

This is what I used but it doesn't work for cross domain (basically remove the iframe element) 这是我使用的，但它不适用于跨域（基本上删除iframe元素）

window.parent.document.getElementById('someId').parentNode.removeChild(window.parent.document.getElementById('someId'));

Can you help? 你能帮我吗？ Thanks. 谢谢。

Answer 1

You should use a library that abstracts this (eg http://easyxdm.net/wp/ , not tested). 你应该使用一个抽象的库（例如http://easyxdm.net/wp/ ，未经过测试）。 Fragment ID messaging may not work in all browsers, and there are better approaches, such as postMessage . 片段ID消息传递可能无法在所有浏览器中使用，并且有更好的方法，例如postMessage 。

However, your example (Clipper) is using a hack called fragment id messaging . 但是，您的示例（Clipper）正在使用称为片段ID消息传递的黑客。 This can be cross-browser, provided the page containing your iframe is the top level. 这可以是跨浏览器，前提是包含iframe的页面是顶级。 In other words, there are a total of two levels. 换句话说，总共有两个级别。 Basically, the child sets the fragment of the parent, and the parent watches for this. 基本上，子项设置父项的片段，父项监视它。

This is a similar approach to Clipper's: 这是与Clipper类似的方法：

parent.html parent.html

<html>
<head>
<script type="text/javascript">
function checkForClose()
{
    if(window.location.hash == "#close_child")
    {
      var someIframe = document.getElementById("someId");
      someIframe.parentNode.removeChild(someIframe);
    }
    else
    {
      setTimeout(checkForClose, 1000)
    }
}
setTimeout(checkForClose, 1000);
</script>
</head>
<body>
<iframe name="someId" id="someId" src="child.html" height="800" width="600">foo</iframe>
</body>
</html>

child.html: child.html：

<html>
<head>
<script type="text/javascript">
setTimeout(function(){window.parent.location.hash = "close_child";}, 5000);
</script>
<body style="background-color: blue"></body>
</html>

EDIT2: Cross-domain and independently controlled are different. EDIT2：跨域和独立控制是不同的。 I dug into the (heavily minified/obfuscated) Polyvore code to see how it works (incidentally, it doesn't in Firefox). 我挖掘了（严重缩小/混淆）Polyvore代码以查看它是如何工作的（顺便说一下，它不在Firefox中）。 First remember that bookmarklets, such as the Clipper, live in the context of the page open when they start. 首先请记住，诸如Clipper之类的bookmarklet在它们启动时会在页面的上下文中生效。 In this case, the bookmarklet loads a script , which in turn runs an init function which generates an iframe , but also runs: 在这种情况下，bookmarklet加载一个脚本，该脚本又运行一个生成iframe的init函数，但也运行：

Event.addListener(Event.XFRAME, "done", cancel);

If you digg into addListener, you'll find ( beautified ): 如果你深入了解addListener，你会发现（美化）：

if (_1ce2 == Event.XFRAME) {
                        if (!_1cb3) {
                            _1cb3 = new Monitor(function () {
                                return window.location.hash;
                            },
                            100);
                            Event.addListener(_1cb3, "change", onHashChange);
                        }
                    }

cancel includes: 取消包括：

removeNode(iframe);

Now, the only remaining piece is that the iframe page loads another script with a ClipperForm.init function that includes: 现在，唯一剩下的部分是iframe页面加载另一个带有ClipperForm.init函数的脚本，该函数包括：

Event.addListener($("close"), "click", function () {
            Event.postMessage(window.parent, _228d, "done");
        });

So we see clearly they are using fragment ID messaging. 所以我们清楚地看到他们正在使用片段ID消息。

Answer 2

尝试隐藏iframe的内容，不要担心实际删除父级中的iframe元素。

Answer 3

There is another implementation of the old hash hack. 还有另一个旧哈希黑客的实现。 It's backwards compatible, easy javascript-only, and very easy to implement: 它向后兼容，简单的javascript，并且非常容易实现：
