It’s not implicit at all, it’s explicit in this line right here: var view = new TodoView({model: todo}); This is creating a new TodoView view and setting its model property to the addOne function’s only parameter (todo, which is a model). Whenever a new model is added to the Todos collection, the addOne method is … Read more
Starting with Chrome 46 you don’t need iframe hacks anymore! All corresponding Chrome issues have been fixed: 1 2 3 Just make sure that the original login form does not “exist” anymore after a push state or an ajax request by either removing (or hiding) the form or changing it’s action url (didn’t test but … Read more
Dust.js is a good option. It is better than some of the other templating frameworks because it does not constrain that the data should be in a file, or in a string, etc. Also it is being actively maintained https://github.com/linkedin/dustjs. Has it been successful? Yes, I know at least LinkedIn is using it and also … Read more
Those properties are used if your view has to create its own element, that is, if it doesn’t have a el attribute when instantiated (various reasons, I can go further in the matter). So you’ll have a new element with the id id, classes className and attributes attributes. You can find the relevant piece of … Read more
The problem is that Inventory.prototype.defaults and Extended.prototype.defaults has the same reference, because you have not override the reference. So you can do this in 2 ways, maybe more but i only found this 2: Edit: The first example is incorrect (see comments); please refer to the second. var ExtendedInventory = Inventory.extend({ defaults: { rabit:25 } … Read more
Backbone’s sync triggers an ‘error’ event when errors occur. So one approach you could take is to extend Backbone’s Model and Collection objects to add these add-on error checks. It would look something like this: ErrorHandlingModel = Backbone.Model.extend({ initialize: function(attributes, options) { options || (options = {}); this.bind(“error”, this.defaultErrorHandler); this.init && this.init(attributes, options); }, defaultErrorHandler: … Read more
I’ve been using e.stopImmediatePropagation(); in order to keep the event from propagating. I wish there was a shorter way to do this. I would like return false; but that is due to my familiarity with jQuery
The easiest way to do this is to call .reset()[docs] on the collection. Calling collection.reset() without passing any models as arguments will empty the entire collection. i.e. collection.reset();
In my ears this sounds a bit on the complex side, at least to start with. Backbone.sync will already report errors that you can catch in your models .save() method: this.mymodel.save(/* … */, {success: function(model, result, xhr)…, error: function(model, xhr, options)…} (docs). If your serverside follows HTTP specs well, the error code is already provided … Read more
Your parse() function shouldn’t set() anything, its a better practice to just return the attributes, Backbone will take care of setting it. e.g. parse: function(response) { response.summaryList = new JobSummaryList(response.summaryList); return response; } Whatever you return from parse() is passed to set(). Not returning anything (which is like returning undefined) is the same as calling … Read more
