Backbone.Overview v0.0.2

Backbone.Overview

An Overview is a View that references and keeps track of sub-views (i.e. just normal Backbone.Views) Kind of like what a Collection is to a Model.

An Overview provides methods for handling the views it keeps track of:

• add(id, view)
• get(id)
• getAll()
• keys()
• remove(id)
• removeAll()

Usage

Include Backbone.Overview after having included Backbone.js:

    <script type="text/javascript" src="backbone.js"></script>
    <script type="text/javascript" src="backbone.overview.js"></script>

Create your overview like this:

    this.RosterView = Backbone.Overview.extend({
    // ... same customizations as you would make for a normal Backbone.View
    });

Underscore

You can use the usual underscore methdods, like you can with Backbone Collections.

For example:

    this.rosterview = new this.RosterView();
    this.rosterview.add(new Backbone.View({model: new Backbone.Model()));

    this.rosterview.each(function (view) {
        // Do something
    });

RequireJS

Include RequireJS:

    <script type="text/javascript" src="lib/require.js"></script>

RequireJS config:

    require.config({
        paths: {
            jquery: "lib/jquery",
            underscore: "lib/underscore",
            backbone: "lib/backbone",
            backbone.overview: "lib/backbone.overview"
        }
    });

    define(["backbone.overview"], function() {
        this.RosterView = Backbone.Overview.extend({
        // ... same customizations as you would make for a normal Backbone.View
        });
    });
