Top page:
前页面:
...
<script>
if (window.addEventListener) {
// addEventListener equivalent of code below
} else if (window.attachEvent) {
window.attachEvent("message", function(e) {
if (e.origin != "page2.html") { return; }
alert(e.data);
});
}
</script>
<iframe src="page2.html"></iframe>
page2.html:
page2.html:
<script>
var message = "hello!";
parent.postMessage(message, '*');
</script>
This code works fine in Chrome, FF and Opera. Of course IE has its own way of doing things so this code doesn't work despite using its own .attachEvent.
这段代码在Chrome、FF和Opera中运行良好。当然，IE有自己的方法，所以尽管使用了它自己的. attachevent，该代码也不能工作。
The page2.html is actually a page on another domain; I'm sending the correct P3P headers ( shouldn't matter, but there's that ).
所以page2。html实际上是另一个领域的一页;我正在发送正确的P3P标题(不重要，但是有这个)。
How do I find out why postMessage doesn't seem to be reaching the parent page?
我怎么知道为什么postMessage似乎没有到达父页面?

attachEvent takes its event name in the form "onmessage", as opposed to addEventListener (which uses "message")
attachEvent以“onmessage”的形式接收其事件名称，而不是addEventListener(它使用“消息”)
