组合选项
使用选项参数可以组合不同类型的监听器:
下面是一个标准的、延迟执行的、一次性的监听器,将会自动停止事件并传递一个自定义的参数(forumId)
el.on('click', this.onClick, this, { single: true, delay: 100, stopEvent : true, forumId: 4 }); 这个方法也允许传递的单个参数是一个包含多个指定处理函数的设置对象。
一次调用多个处理函数
代码:
el.on({ 'click' : { fn: this.onClick scope: this, delay: 100 }, 'mouseover' : { fn: this.onMouseOver scope: this }, 'mouseout' : { fn: this.onMouseOut scope: this } }); 或者简写为:
代码:
el.on({ 'click' : this.onClick, 'mouseover' : this.onMouseOver, 'mouseout' : this.onMouseOut scope: this });
