Adding The Listening Event Code

Add this JS function for listening to events fired by Stamped:

function addEventListenerStamped(el, eventName, handler) {
if (el.addEventListener) { el.addEventListener(eventName, handler); }
else { el.attachEvent('on' + eventName, function () { handler.call(el); }); }
}

// Listening for event
addEventListenerStamped(document, '##replaceWithEventName##', function(e) {
'##replaceWithFunction##'
});

// Example
// Listening for launcher loaded event
addEventListenerStamped(document, 'stamped:launcher:loaded', function(e) {
StampedFn.toggleRewardsModal();
});
