Safely adds events in window.iAdvizeCallbacks object

If you need to add iAdvize callbacks in different places in your code, you should always declare your callbacks like the following example to avoid overwriting a previous callback definition:

window.iAdvizeCallbacks = {
  ...window.iAdvizeCallbacks,
  
  onChatStarted() {
    // Do something
  },
  
  onChatEnded() {
    // Do something
  }
  
};

// Later in your code:
window.iAdvizeCallbacks = {
  ...window.iAdvizeCallbacks,
  
  onMessageReceived(context) {
    // Do something
  }
  
};

With this approach, iAdvize will see 3 callbacks: onChatStarted, onChatEnded et onMessageReceived.

Safely define a function for an event

If your code is splitted in multiple files or module, you may need to define several functions for the same event.

Here is a solution to avoid overwriting a previous function:

var tempOnChatStarted = window.iAdvizeCallbacks.onChatStarted || () => {};

window.iAdvizeCallbacks = {
  ...window.iAdvizeCallbacks,
  
  onChatStarted(context) {

    // Call the possible already defined callback
    tempOnChatStarted(context);

    // Your new custom code here
    // ...
    
  }
  
};

Track some Google Analytics events

window.iAdvizeCallbacks = {

  ...window.iAdvizeCallbacks,
  
  // Chat conversation starts
  onChatStarted(context) {
    _gaq.push(['_trackEvent', 'iAdvize', 'Chat Start', context.startedBy]);
  },
  
  // Chat conversation ends
  onChatEnded(context) {
    _gaq.push(['_trackEvent', 'iAdvize', 'Chat End', context.startedBy]);
  },
  
  // Call conversation starts
  onCallStarted() {
    _gaq.push(['_trackEvent', 'iAdvize', 'Call Start']);
  },
  
  // Call conversation ends
  onCallEnded() {
    _gaq.push(['_trackEvent', 'iAdvize', 'Call End']);
  }

};
