javascript - backbone.js + google.maps api v3 + overlayview = 使用backbone进行原型(prototype)设计

Question

我读过:

Mixing Google Maps custom overlays with Backbone Views

并尝试实现和玩弄它，因为我需要使用自定义叠加层作为 View ，并且我已经使用backbone.js

var Label = function(){
        Backbone.View.apply(this, arguments);
        this.newInit();
    };

    Label.extend = Backbone.View.extend;

    _.extend(Label.prototype, Backbone.View.prototype, google.maps.OverlayView.prototype,{
        newInit: function(){
         this.setMap(this.options.map);
        },
        onAdd: function(){...},
        onRemove: function(){...},
        draw: function(){...}
    });

    var label_view = new LabelView({map: map});
    label_view.bindTo('some_event', {name: 'some_event_occured'});

根据我的测试，“draw”方法没有被调用，尽管它应该覆盖它。我做错了什么？

Answer 1

找到解决方案:

var Label = function(){
        Backbone.View.apply(this, arguments);
        google.maps.OverlayView.apply(this, arguments);
    };

而不是

newInit: function(){

用途:

initialize: function(options){

希望这有帮助
