Issue with Window.parent.postMessage Ack

Question

I am using window.parent.postMessage to communicate with a client. The client at the moment can only handle one record at a time. I have to send them one record, wait for a response, send them a second record. The second order is never sent because my flag is always null event though it's being set in the event listener.

This is my send message Method:

   var SendMessage = function (Record, count, readyForNextRecord) {
    if (Record.length > 0) {
        var response = sessionStorage.getItem("response");;
        if (readyForNextRecord === true) {
            var url = (window.location != window.parent.location) ? document.referrer : document.location;
            window.parent.postMessage(Record[count], url);
            count++;
        }
       if(count < Record.length){
         if (response == null) {
            interval =   window.setInterval(SendMessage(Record, count, false), 100)
          } else {
              response = null;
              clearInterval(interval);
             window.setTimeout(SendMessage(Record, count, true), 100);
          }
    }
}

The event listener

window.addEventListener("message", ReceiveMessage, false);

var ReceiveMessage = function (event) {
    for (var val in event.data) {
        var message = event.data[val];
        switch (message.toString().toLowerCase()) {
            case "success":
                sessionStorage.setItem("response", true);
                break;
            case "failure":
                sessionStorage.setItem("response", false);
                break;
            default:
                break;
        }
    }
}

In the end, I reached the maximum call stack size:

Uncaught RangeError: Maximum call stack size exceeded

I did as @Shilly suggested, and it's been working as expected. I changed this line of code below to use

I changed this line of code

interval =   window.setInterval(SendMessage(Record, count, false), 100) 

To

 window.setTimeout(SendMessage(Record, count, false), 200);
