Subscribe to Events
Use the <component>.on(event, event_handler) method for a component to create a listener and subscribe to an event.
Each listener takes two arguments:
-
event– declares the name of the event to listen to. -
event_handler– declares the function to process the results of the operation that triggered the event. In general, each event handler receives a single argument.
The following code example shows how to subscribe to the afterOptionSelection event for the PDP and then log the result to the browser console:
var pdp = container.getComponent('PDP');
// ...
pdp.on('afterOptionSelection', function(event) {
console.log('option ' + event.optionCartId + ' was selected with value ' + event.value)
});
