问题描述
我有一个主干视图，它使用实现幻灯片。
I have a Backbone View that uses iScroll to implement a slideshow.
iScroll发布一个 onScrollEnd 事件，但我似乎无法在视图内绑定/订阅： p>
iScroll publishes an onScrollEnd event, but I cannot seem to bind/subscribe to it inside the View:
App.Views.Scroller = Backbone.View.extend({
events: {
'onScrollEnd' : 'scrollEnd'
},
initialize: function(){
var self = this;
this.scroller = new iScroll('content-scroller', {
onScrollEnd: function() {
self.trigger('onScrollEnd');
}
});
},
scrollEnd: function(e){
// never called :(
console.log(e);
}
});
推荐答案
您的onScrollEnd事件绑定到视图的顶部元素; scrollEnd将当视图的HTML元素接收到onScrollEnd事件时调用。
Your onScrollEnd event is bound to the view's top element; scrollEnd will be called when the view's HTML element received an onScrollEnd event.
但是您触发了View对象上的onScrollend事件而不是元素。
But you are triggering an onScrollend event on your View object, not the element.
所以你可能想说 $（self.el）.trigger（'onScrollEnd'）; ，或者直接调用函数： self.scrollEnd（）。
So you probably want to say $(self.el).trigger('onScrollEnd'); instead, or perhaps call the function directly: self.scrollEnd().
