What browsers support the window.postMessage call now?
JavascriptCross BrowserJavascript Problem Overview
What are all the browsers that support the window.postMessage call now? I am looking for browsers that support it natively, not through an iFrame hack.

Solution 3 - Javascript
postMessage is supported in IE8+ HOWEVER
- 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.

Solution 4 - Javascript
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:
if(window.postMessage){
console.log('Supports post message');
}
Or likely a bit cleaner:
var pm_is_supported = typeof(window.postMessage) == 'function';
Solution 5 - Javascript
All latest browsers supports that e.g. IE 11, Edge, Firefox 57+, Dafari 11+, iOS Safari 10.2+, Opera mini, Chrome for android, UC Browser etc.
