Backbone - What is the best way to listen to 2 models?
Tag : javascript , By : Kbotei

around this issue I'm working on a project and I was curious as to what is the best way to listen to 2 objects that are used in the same function? , Create a base model and inherit from your other models:
    var DataModel = Backbone.Model.extend({
        // ToDo
    });

    var FileModel = DataModel.extend({
        // ToDo
    });

    var FolderModel = DataModel.extend({
        // ToDo
    });
    var DataCollection = Backbone.Collection.extend({
        model: DataModel
    });

To fix this issue This is beacuse you are binding a listener to the wrong object. Try this in your View :
window.ThingView = Backbone.View.extend({

    initialize: function() {
            myRouter.on('route:showThing', this.anything);
    },

...

      console.log("Someone's child is hungry");
    });// listening to child hungry
