问题 How can I fire a named action upon changing a checkbox in Ember.js? Any help will be greatly appreciated. Here is what I have. Checking or unchecking the checkbox has no effect. Template: {{input type="checkbox" on="change" action="applyFilter"}} Controller: actions: { applyFilter: function() { console.log("applyFilter"); } } 回答1: using an observer seems like the easiest way to watch a checkbox changing Template {{input type='checkbox' checked=foo}} Code foo:undefined, watchFoo: function(){

问题 I have a component that needs to communicate with a controller and eventually perform some clean up after the controller says everything is ok (ie, jQuery "un"-initialization). I think the best way to accomplish this is with a promise so that the component can clean up after the controller completes its task. But how can a controller action return a promise? Alternatively, can a component call a dynamic method directly on a controller? For example, lets say I have a ModalDialogComponent . App

问题 Can anyone explain what the purpose of the Container module is in the latest Ember? An example of its usage, in the setup and in the start of this test: module("Ember.View - handlebars integration", { setup: function() { Ember.lookup = lookup = { Ember: Ember }; lookup.TemplateTests = TemplateTests = Ember.Namespace.create(); container = new Ember.Container(); container.optionsForType('template', { instantiate: false }); } test("template view should call the function of the associated

问题 We are using version pre4 of ember. We have a framework (SignalR) working parallel with ember that handles real-time notifications to our application. In the older versions of ember we were able to access the global reference of the router / controller. But with the new version of Ember this is no longer possible. (This is fine) We have tried different approaches like setting up a global controller in the top route: setupController: function(){ app.appController = this.controllerFor('app'); }

问题 Ember data is still not at version 1.0 and thus I decided to use Ember without Data models. I have my own models, and those are created by the route model function. However maintaining state between the frontend objects and the backend objects is a nightmare. Especially when one route uses another routes models. How can this be achieved, should I write my own store and model find method? Should I use Ember Data (even though it's not at version 1.0 ?) perhaps an ETA on Ember Data 1.0 ? write

问题 I am new to Ember and have posted a similar post regarding troubleshooting of a simple Ember front-end with JSON API web back-end (see below). My problem here is that I am unable to get Postman to display any data in the DevTools console - its blank. I can use Postman to submit requests and see the response in the body, that is all. I have tried various permutations of using the application while going so far as to uninstall and re-install. But, nothing is working. Is anyone aware of the

问题 []I am trying to feed data (via an ajax call to a json file) to both a handlebars template and a leaflet map. With my current setup, the data reaches my handlebars template just fine, but doesn't render the coordinates data to the leaflet map. I suspect I am missing some basic piece of the ember.js puzzle.
