javascript - Backbone : Can't remove a view when call method remove()

Question

我尝试删除包含在 map 中渲染的制造商的 View 。当我单击按钮时，事件 click .ver 被激活，但没有任何反应，并且我收到以下错误:Uncaught TypeError: undefined is not a function。我不知道我做错了什么。

我的代码:

ev.views.Home_Eventos = Backbone.View.extend({
    initialize: function(map){
        this.template = _.template(ev.templateLoader.get('home_list_eventos'));
        this.map = map;
        //console.log(this.map);
        this.render(this.map);
    },

    events: {
        'click .ver' : 'teste'  
    },

    teste: function(){
        ev.views.Markers.remove();
    },

    render: function(map){
        var that = this;
        that.map = map;
        var imagens = new ev.models.ImagemCollection();
        imagens.fetch({
            success: function(){
                that.$el.html(that.template({imagens: imagens.models}));
                var marcadores = imagens.models;
                    setTimeout(function() {
                    that.local(that.map);
                    var marcadores = new ev.views.Markers(that.map);
                }, 0);
                return that;
            }
        });
    }

});

ev.views.Markers = Backbone.View.extend({
    initialize: function(map){
        this.map = map;
        this.render(this.map);
    },

    render: function(map){
        var that = this;
        var imagens = new ev.models.ImagemCollection();
        imagens.fetch({
            success: function(){
                var marcadores = imagens.models;
                    setTimeout(function() {
                    _.each(marcadores, function(marcador){
                        var myLatlng = new google.maps.LatLng(marcador.get('latitude'),marcador.get('longitude'));
                        var marker = new google.maps.Marker({
                            position: myLatlng,
                            map: that.map,
                        });

                    });
                }, 0);

                return that;
            }
        });
    }

});

您需要保留对要删除的 View 的引用。例如，您有:

var marcadores = new ev.views.Markers(that.map);

您可以通过执行以下操作来保存 View 上的引用:

that.marcadores = new ev.views.Markers(that.map);

然后在你的事件处理程序中，

teste: function(){
    this.marcadores.remove();
},

这会破坏您创建的 Marker View ，但可能不会清除该 View 管理的 Google map 标记。
