javascript postMessage无效 [英] javascript postMessage not working
问题描述
我不知道该怎么办。我尝试了不同来源的几个示例代码，我在不同的浏览器（从Chrome 9到FF 4）中尝试过它们，但似乎仍然没有使用postMessage功能。
JS控制台没有给我任何东西，没有一个错误，仍然没有发生任何事情：框架不想进行通信。完全没有。这甚至不是跨域的：两个帧都来自我的域。
I don't know what to do. I tried several sample codes from different sources, I tried them in different browsers (from Chrome 9 to FF 4), and still nothing seems to be working with the "postMessage" function. JS console is giving me nothing, not a single error, still nothing is happening : the frames don't want to communicate. At all. And this isn't even cross-domain : both frames are from my domain.
以下是上次尝试的示例代码：
父框架：
Here is a sample code from the last try : Parent frame :
<iframe src="IFRAME_URL"></iframe>
<script>
window.addEventListener( "message",
function (e) {
if(e.origin !== 'DOMAIN'){ return; }
alert(e.data);
},
false);
</script>
子框架：
<html>
<head></head>
<body>
<script>
top.postMessage('hello', 'DOMAIN');
</script>
</body>
非常感谢，谢谢很多
推荐答案
你的 postMessage 的第二个参数必须是一个url http：// localhost
The second parameter of your postMessage must be an url like http://localhost
