Backbone Object render没有方法适用 - bind问题

所以我在AppView中这样做

var flowerModel = new app.DataModel({title: "flower", values: ["tulip","rose","dandelion"], dataToShow:["tulip", "rose", "dandelion"], data: data});
    var timelineModel = new app.TimeChartModel({data: flowerModel.getDisplayedData(), titlesToShow: flowerModel.get('dataToShow')});


    tableCollection.add(flowerModel);

    var timechart = d3.select("body").append("div").attr("class","timechart");

    this.centerView = new app.TimeChartView({model: flowerModel, el : timechart});
    this.rightView = new app.TableView({model: flowerModel});

在我的TimeChartView init方法中,我这样做 -

initialize: function(){
        this.model.bind('change','render');
            //other, irrelevant things

}

并且在我的flowerModel中我有这个方法,当勾选一个复选框时它会起作用 -

events: {
    'click .data-type' : 'collapseDatum',
    'click .show-datum' : 'addDatumToShow',
},

addDatumToShow: function(e){
        var test = $(this.$el).find(".datum-list").find(":checked");
        newDataToShow = [];
        _.each(test, function(value,key,list){
            var title = $(value).data("title");
            newDataToShow.push(title);
        });
        this.model.set("dataToShow", newDataToShow);
    },

错误发生在this.model.set('dataToShow',newDataToShow)上。

我真的不确定为什么,关于如何调试的任何建议都会有所帮助。我不认为我做了什么疯狂,或者在这里不寻常。

答案 0 :(得分:1)

试试这个:

flowerModel.bind('change:dataToShow', function() { 
    timelineModel.set('titlesToShow', flowerModel.get('dataToShow')); 
});

this.model.bind('change', this.render);
