Question

I need to create custom events in a javascript NameSpace, but i dont know if its possible.

I have a namespace like this:

NAMESPACE = {

   var1 : 'value',
   var2 : 'value',

   initiate : function() {
      console.log('initiate');
   },

   clear : function(arg) {
      console.log('clear');
   }

   fail : function() {
       // Here i need to trigger the error event..
   }

}

That creates events using this method:

var myEvent = new CustomEvent("errorX", {
  data: {
    param: "value"
  }
});

document.dispatchEvent(myEvent);

// In document.ready...
$(document).on('errorX', function(e) {
   console.log(e);
});

This works, but I need to attach the addEventlistener to the document and I would like to attach this to the namespace object, like:

$(NAMESPACE).on('errorX', function(e) {
    console.log(e);
});

It this possible?

You can use the .triggerHandler method:

$(NAMESPACE).on('errorX', function(e) {
    console.log(e);
});

$(NAMESPACE).triggerHandler("errorX");
