Pass an Event to an iframe from the parent window? ( Javascript )

Finally I have sorted out the issue. I have used parent.document on my iframe to catch the events from the parnet side and create them again on iframe and it works great!

you want something like this:

var iframe = document.getElementById('something');
var iframeEvent = new Event('iframe-keypress');

document.addEventListener('keypress', function (e) {
    iframe.dispatchEvent(iframeEvent);
});

iframe.addEventListener('iframe-keypress', function (e) {
    console.log(e);
});

listen for the event on the document then pass down a custom event to the iframe.

Use postMessage. It works perfectly.

document.getElementById('vid').contentWindow.postMessage(event);
