在IE10中跨原点postMessage是否断开？ [英] Is cross-origin postMessage broken in IE10?
问题描述
我试图做一个微不足道的 postMessage 示例工作...
I'm trying to make a trivial postMessage example work...
- 在IE10
- 在窗口/标签（与iframe之间）
删除这些条件中的任何一个，并且事情很好： - ）
Remove any one of these conditions, and things work fine :-)
但是据我所知， postMessage 仅在两个窗口共享一个原点时在IE10中工作。 （事实上，奇怪的是，这种行为稍微宽松一些：共享一个主机的两个不同的起源似乎也起作用了。）
But as far as I can tell, between-window postMessage only appears to work in IE10 when both windows share an origin. (Well, in fact -- and weirdly -- the behavior is slightly more permissive than that: two different origins that share a host seem to work, too).
（注意：此问题涉及问题，但它的回答是关于IE8和IE9 - 不是10）
(Note: This question touches on the issues, but its answer is about IE8 and IE9 -- not 10)

More details + example...
<!DOCTYPE html>
<html>
<script>
window.addEventListener("message", function(e){
console.log("Received message: ", e);
}, false);
</script>
<button onclick="window.open('http://jsbin.com/ameguj/1');">
Open new window
</button>
</html>
启动页面演示
launched page demo
<!DOCTYPE html>
<html>
<script>
window.opener.postMessage("Ahoy!", "*");
</script>
</html>
这适用于： http://jsbin.com/ahuzir/1 - 因为这两个网页托管在同一个来源（jsbin.com）。
This works at: http://jsbin.com/ahuzir/1 -- because both pages are hosted at the same origin (jsbin.com). But move the second page anywhere else, and it fails in IE10.
推荐答案
当我最初发布的时候答案：它实际上不工作在IE10。显然，人们发现这有用的其他原因，所以我把它留给后代。原始答案如下：
I was mistaken when I originally posted this answer: it doesn't actually work in IE10. Apparently people have found this useful for other reasons so I'm leaving it up for posterity. Original answer below:
值得注意的是：您链接的答案中的链接指出 postMessage 在IE8和IE9中不是单独的窗口的交叉原点 - 然而，它也是在2009年，IE10到来之前写的。
Worth noting: the link in that answer you linked to states that postMessage isn't cross origin for separate windows in IE8 and IE9 -- however, it was also written in 2009, before IE10 came around. So I wouldn't take that as an indication that it's fixed in IE10.
对于 postMessage 本身而言， a href =http://caniuse.com/#feat=x-doc-messaging> http://caniuse.com/#feat=x-doc-messaging 明显表示它在IE10中仍然损坏，这似乎与您的演示匹配。 caniuse页面链接到本文，其中包含非常相关的报价：
As for postMessage itself, http://caniuse.com/#feat=x-doc-messaging notably indicates that it's still broken in IE10, which seems to match up with your demo. The caniuse page links to this article, which contains a very relevant quote:
Internet Explorer 8+部分支持跨文档消息传递：it
目前与iframe一起使用，但不支持新窗口。但是，Internet Explorer
10将支持MessageChannel。 Firefox目前支持
跨文档消息，但不支持MessageChannel。
Internet Explorer 8+ partially supports cross-document messaging: it currently works with iframes, but not new windows. Internet Explorer 10, however, will support MessageChannel. Firefox currently supports cross-document messaging, but not MessageChannel.
c $ c> MessageChannel 的代码路径，并且如果不存在则回退到 postMessage 。
So your best bet is probably to have a MessageChannel based codepath, and fallback to postMessage if that doesn't exist. It won't get you IE8/IE9 support, but at least it'll work with IE10.
