Reset to default 3You can use postMessage in order to municate between 2 iframe.
On the parent frame you need to grab the iframe's window with iframeEl.contentWindow.postMessage(value as a string, can be json.stringified value)
On the child frame you need to add event of type message, something like that:
window.addEventListener('message', function(dataPassed) {
//Your logic here.
})
For more info read that
<html>
<head>
<title>
</title>
<script>
function sendvalue(v){
document.getElementById('va').value = v;
window.frames['framename'].document.getElementById("a").value = v
}
</script>
</head>
<body>
<form id="f">
<input type="button" value="123" onclick="sendvalue(this.value)">
<input type="text" name="va" id="va">
</form>
<iframe name="framename" src="a.html" width="500px;"></iframe>
</body>

a.html

The Best way it to add to you Iframe
<iframe id="frame1" src="a.html?data=SomeData" width="500px;"></iframe>
and inside the iframe you can get the information by making varible
var MYDATA = location.href.split('=')[1].split('&');
(you will see that MYDATA=SomeData)
