问题 I'm trying to render a list with a Marionette CompositeView. I am not sure why the rendered list just has an item displaying the word result . I was expecting the first item to display Level 1 . Here is a fiddle to my current code: http://jsfiddle.net/16L1hen4/ Here is my JS, template, and data: JavaScript: var App = new Backbone.Marionette.Application(); App.addRegions({ mainRegion: '#main' }); var TreeModel = Backbone.Model.extend({ }); var TreeCollection = Backbone.Collection.extend({

问题 I am trying to render a backbone collection of views. The collection could be any kind of marionette view ( layoutView, CompositeView, collectionView, ItemView). When I try and render, I get “[object Object]” for each view that renders. This leads me to believe that it doesn't know which view to render when it grabs one from the collection.

问题 I'm migrating a Backbone basic app to Marionette and I would like to use ICanHaz.js as a template system (based on Mustache). I'm using AMD and Require.js and the only way to make ICanHaz.js working with it and Backbone was to use jvashishtha's version. I first implemented the app in pure Backbone style. In particular I used to load each template as raw strings with the Require.js' text plugin and then add the template to the ich object. This create a method in ich object that has the same

问题 I'm trying to prevent the user from making an edit to a model via form and easily navigating away from that change. Think Gmail when you've started composing a message. Someone has posted an issue on GitHub that describes the same situation. https://github.com/marionettejs/backbone.marionette/issues/186 This issue was closed because people suggest you should detect changes before attempting to close a view. But the problem with this approach is there there are several ways a view can be

问题 In my application i added Marionette.sync plugin and override these methods: Backbone.Marionette.TemplateCache.prototype.loadTemplate = function (templateId, callback) { var tmpId = templateId.replace("#", ""), url = "/app/templates/" + tmpId + ".html"; $.get(url, function (templateHtml) { compiledTemplate = Handlebars.compile($(templateHtml).html()) callback.call(this, compiledTemplate); }); }; Backbone.Marionette.Renderer.renderTemplate = function (template, data) { template(data); }; But

问题 Trying to populate a Collection from a list of values, I am getting an error about the Collection's model 's prototype being undefined. Looking at this question about a similar problem, I have checked that the Model is actually created before the collection is instanced, to the best of my ability. The error is being thrown in one of the event handlers of the Marionette CompositeView that holds the Collection, after fetching the data from the server and trying to reset the collection with the

问题 UPDATE (RELEVANT DETAIL): This composite view is within a collection of composite views. How can I construct the following HTML using a Backbone.Marionette composite view? <optgroup label="Group 1"> <option>Item 1</option> <option>Item 2</option> <option>Item 3</option> </optgroup> <optgroup label="Group 2"> <option>Item 4</option> <option>Item 5</option> <option>Item 6</option> </optgroup> Since I want to avoid the <div> wrapper, I will have to specify <optgroup> as the tagName. view =
