How to attach Backbone.Marionette view to existing element without creating extra element

阅读更多关于 How to attach Backbone.Marionette view to existing element without creating extra element

Say I have these two Backbone.Marionette views: var FooView = Backbone.Marionette.ItemView.extend({ tagName: p, id: 'foo', template: this.templates.summary }); var BarView = Backbone.Marionette.ItemView.extend({ template: this.templates.summary }); And then I want to show them inside an app region, like so: App.contentRegion.show(new FooView/BarView()); The first view would create a new element and append it to the region. I thought the second way would be more like a standard Backbone view and attach itself to the region without creating a new element, but it wraps it in a tag. Is there a way

How do you properly display a Backbone marionette collection view based on a model javascript array property?

阅读更多关于 How do you properly display a Backbone marionette collection view based on a model javascript array property?

* UPDATE : See final answer code in the last code block below.* Currently I am having an issue displaying a collection in a collection view. The collection is a property of an existing model like so (pseudo code) ApplicationVersion { Id: 1, VersionName: "", ApplicationCategories[] } So essentially ApplicationVersion has a property called ApplicationCategories that is a javascript array. Currently when I render the collection view associated with ApplicationCategories nothing is rendered. If I debug in Chrome's javascript debugger it appears that the categories have not been populated yet (so I

Backbone.Marionette CollectionView callback when all itemViews have finished rendering?

阅读更多关于 Backbone.Marionette CollectionView callback when all itemViews have finished rendering?

I'm using the marionette Layout .show to render a CollectionView and was wondering if there is a way of detecting when all the ItemView children have finished rendering? A simplified version of my code is: Layout Layouts.Group = Backbone.Marionette.Layout.extend({ template: Templates.group, ... regions: { header: ".group-header" details: ".group-details" }, ... }); CollectionView Views.GroupDetail = Backbone.Marionette.CollectionView.extend({ itemView: groupDetailRow, ... onRender: function () { // do something here after rendering *all* groupDetailRows of information for group detail section

Routing in Backbone.js / Marionette.js - no hashtags, route list and sub-routers

阅读更多关于 Routing in Backbone.js / Marionette.js - no hashtags, route list and sub-routers

问题 I have three questions about routing in Backbone.js / Marionette.js : 1) How can I get a list of all the routes my application's routers have registered ? For example for Express.js (in Node.js) it would be app.routes . I'm trying to do the same with Backbone.js / Marionette.js but couldn't find any property or method that did this. 2) I want to clean-up my URLs and remove the hashtag "#" in front of them, I know that they trigger the Routers so how can I manage to do this ? I found the

How to define/use several routings using backbone and requirejs

阅读更多关于 How to define/use several routings using backbone and requirejs

问题 I divided my app in several apps. main.js app.js app1/ |- routing |- controller |- app app2/ |- routing |- controller |- app 1) When I try to use the routers in app1 , they work. 2) When I try to use the routers in app2 , they don't work. 3) If I comment the line 'js/app1/routing', in main.js the routers in app2 work. Why do I get this behaviour? Is there some example of app using multiple routing and requirejs on github? thanks. Here's my code: ** main.js ** define([ 'js/app', 'js/app1

Two Collections inside a Composite View

阅读更多关于 Two Collections inside a Composite View

问题 So we are working on a project using marionette and we have made a good progress so far, but we struggling with a part of the marionette nested view model, so lets assume that we have an apartment (represented as a composite view), and the apartment contains a collection of rooms and a collection of chairs, what we want to do is have the rooms and chairs a direct descending of the aprtment composite view, how can we do this, knowing that the composite view can only have one child collection,

Dynamically add regions to Marionette layout

阅读更多关于 Dynamically add regions to Marionette layout

I have a layout, but cannot define all of its regions in advance because they are not known. So later on an ItemView is created and I'd like to create a new region in the layout using the view's ID as the region's name so I can then say: layout.dynamicRegionName.show(newItemView); But there is cyclic dependency here. I haven't rendered the view yet, so I cannot make a reference to its DOM element to be used in the layout's call to .addRegion() I cannot render it, precisely because I want it to get attached to the DOM tree through the dynamically added region by calling its .show()

What is the difference between url vs urlRoot

阅读更多关于 What is the difference between url vs urlRoot

I would like to know what is the difference between using url or urlRoot . I have read the documentation ( backbonejs.org/#Model-url ), but I still feel that I lack knowledge in this area and I would like to know more. When do you have to use url ? And in another instance when do you have to use urlRoot ? .urlRoot is only available in a Model, and is only useful when either a model is not part of a collection, or when you want to override the .url property of the collection which that model is part of. In other words, a model doesn't require neither .url nor .urlRoot property when it is part
