What browsers support the window.postMessage call now?
提问by Jamey McElveen
What are all the browsers that support the window.postMessagecall now? I am looking for browsers that support it natively, not through an iFrame hack.
window.postMessage现在支持通话的浏览器都有哪些？我正在寻找原生支持它的浏览器，而不是通过 iFrame hack。

postMessage is supported in IE8+ HOWEVER
但 IE8+ 支持 postMessage
- Remember that IE9 and below require data to be passed in string form and not as an object.
- IE doesn't like you to call
postMessageas soon as page loads (I'm assuming this has to do with the iframe you are posting to needing time to load).
Use asetTimeoutto wait one or two seconds before callingpostMessage.
It took me hours to figure this out and IE wasn't giving me any error message, it was just silently doing nothing until I added the setTimeout.
- 请记住，IE9 及以下要求以字符串形式而不是对象形式传递数据。
- IE 不希望您在
postMessage页面加载后立即调用（我假设这与您发布的 iframe 需要加载时间有关）。在调用之前
使用 asetTimeout等待一两秒钟postMessage。
我花了几个小时才弄清楚这一点，IE 没有给我任何错误消息，它只是默默地什么都不做，直到我添加了 setTimeout。

For what it's worth recently I ran into some odd webkit browser/versions out in the wild that did NOT support postMessage. I was using IE(8) detection as my means for seeking an alternative. Instead, I probably should have just done some something like this:
对于最近的价值，我在野外遇到了一些不支持 postMessage 的奇怪的 webkit 浏览器/版本。我使用 IE(8) 检测作为寻找替代方案的手段。相反，我可能应该做一些这样的事情：
if(window.postMessage){
console.log('Supports post message');
}
Or likely a bit cleaner:
或者可能更干净一点：
var pm_is_supported = typeof(window.postMessage) == 'function';
