Frontend two-way communication

Frontend API is a two-way communication between Tom Horn Gaming and the game embedded inside the iframe. Implementation uses cross-origin communication between “window” objects via “window.postMessage” function and “message” event. As the game is embedded in the iframe, it sends a message to the parent window. 

Sending message example: 

window.parent.postMessage(message, "*");

To receive messages, subscribe to “message” event:

window.addEventListener("message", function(event){ 
    //event.data is a message that's been sent from the EM window.
    console.log(event.data); 
});

Message data is a JavaScript object in the following format:

{
    "name": "messageName", 
    “sender”:”game”, “data”: 
    “any data object”
}

The object parameters Name and Sender are common for all message types. The use of the parameter Data varies depending on the message.

Stop Auto Spins 

A message is sent from Tom Horn to the game to stop auto spins. This kind of message is usually sent by Tom Horn when a modal window is about to appear, and the user is not able to interact with the game. Its primary purpose is to offer a unified approach to displaying any license-specific functionality within the iframe, for example, MGA and UKCG reality checks. 

Example: 

{ 
  "name": "stopAutospins", 
  "sender": "emwindow" 
}
