: Object Combining Options
Using the options argument, it is possible to combine different types of listeners:
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
el.on('click', this.onClick, this, { single: true, delay: 100, stopEvent : true, forumId: 4 });
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers.
Attaching multiple handlers in 1 call
Code:
el.on({ 'click' : { fn: this.onClick scope: this, delay: 100 }, 'mouseover' : { fn: this.onMouseOver scope: this }, 'mouseout' : { fn: this.onMouseOut scope: this } });
Or a shorthand syntax:
Code:
el.on({ 'click' : this.onClick, 'mouseover' : this.onMouseOver, 'mouseout' : this.onMouseOut scope: this });
