I find the question perfectly valid and from my point of view there is nothing wrong with inquiring about the potential use cases of a library/toolkit. What Backbone.js does (so do several other javascript mvc implementations) is that it provides a means of organizing the code into a modular pattern known as MVC pattern which … Read more
_.bindAll( this, … ) is necessary not only for this.$( selector ).doSomething() but generally to be sure that this in your view’s method is always pointing to the view itself. For example, if we want to refresh our view when the model changes, we bind the view’s render method to the model’s change event: initialize: … Read more
Using handlebars.js instead of underscore templating is pretty straightforward. Check out this example: https://cdnjs.com/libraries/backbone.js/tutorials/what-is-a-view (scroll to the “Loading a Template” section) SearchView = Backbone.View.extend({ initialize: function(){ this.render(); }, render: function(){ // Compile the template using underscore var template = _.template( $(“#search_template”).html(), {} ); // Load the compiled HTML into the Backbone “el” this.el.html( template ); … Read more
Just found similar problem where the issue was solved. You have to put something as first parameter (I put null since my model was already populated with data explicitly) and object with callbacks as second. So something like; sessionsModel.save(null, {success:function() {} });
There’s a discussion on this very topic that you might want to look at: https://github.com/documentcloud/backbone/issues/41. The short of it is that when a user selects ‘sort by X’, you can: Set the comparator function on the Collection Call the Collection’s sort function (which will trigger a sort event) Listen for the sort event in your … Read more
a working binding for example above… http://jsbin.com/ivumuz/2/edit it demonstrates a way for working around Backbone Models with AngularJS. but setters/getters connection would be better.
The underscore.js library provides an extend method that does what you want. You can define functionality on any object, and then quite literally copy & paste all of the methods and attributes from that object to another. Backbone’s extend methods on Views, Models, and Routers are a wrapper around underscore’s extend. var MyMixin = { … Read more
listenTo is the newer and better option because these listeners will be automatically removed for you during stopListening which is called when a view gets removed (via remove()). Prior to listenTo there was a really insidious problem with phantom views hanging around forever (leaking memory and causing misbehavior) because view methods were referenced as event … Read more
Collection.fetch() will call reset on success, which in turn will trigger a ‘reset’ event. Any subscribers to the collections reset event should receive the event. The key here is “on success.” I had this problem, only to discover that backbone was silently swallowing my errors messages. Pass in an error handler that, at least, logs … Read more
Layouts and Regions serve very different purposes: a layout is a type of view, but a region will display a view in your HTML/DOM for you. A region may be used to display a layout. And a layout will also contain regions. This creates a nested hierarchy that can extend infinitely. Region A Region manages … Read more
