Observing a property on a service from a route in EmberJS

由 家住魔仙堡 提交于 2020-01-02 03:24:08
问题 I think I'm not understanding a concept here. As far as I know any Ember.object can observe properties on another Ember.object . So, I have a service, a router, and a component. I need the component and the router to be able to observe a property on the service. It's entirely possible that I'm just structuring the solution in the wrong way, I'll include an overview of what I'm trying to do at the end. Here is approximately what I have: /services/thing-manager.js export default Ember.Service

Pass a reference of the clicked DOM element to the action handler in Ember

问题 I have a set of buttons whose state I wish to toggle with a class active . If I had a single button, then I would bind the active class to a controller property and toggle that property in the click handler: <button {{action 'toggle'}} class="{{active}}">model.title</button> actions: { toggle: function() { this.set('active', true); } } But I have multiple buttons, so I am not sure what I can bind. It would be useful if I could pass a reference to the clicked button to the action handler, but

Ember.js - Prevent re-render when switching route

由 梦想与她 提交于 2020-01-01 19:19:07
问题 Simplified demo: http://jsfiddle.net/indream/KskXx/ (this demo cannot simulate actual environment with my problem) For the demo: Hover on photos will show you the caption. When you clicked a photo, route changed to 'media' with {{linkTo}} helper & lightbox opened. When clicked place outside lightbox, route changed back to 'feed' by history API & lightbox closed. My question : Template re-rendered when switch back to 'feed'. (You can check it by hover on photos as caption lost after that.) I

问题 I have a again which I can't answer for my self properly, maybe because of my lack in expierience with EmberJS.

So far so good, but since alot of people will work with the data inside this application, i would really like to use a WebSocket adapter implementation for EmberJS, since every connected client should always know about changes in entities

How can I make custom events that bubble through the view hierarchy?

由 孤街浪徒 提交于 2020-01-01 12:49:26
问题 I have button views that are part of a set of Ember.js form helpers I wrote. E.g. MyAddressFormView has the following template: {{#form}} {{textArea address}} {{submitButton}} {{cancelButton}} {{/form}} To handle the "Submit" button, I let the "submit" form event bubble, and handle it in the submit method of MyAddressFormView. But how do I do the same for the "Cancel" button? For instance, is there any way I can trigger a custom "cancel form" event in a child view, let it bubble, and handle
