问题 I am writing an Ember.js application, and I would like to run the following Javascript code on a div with a class of navbar right after the view renders: $('.navbar').affix({offset: -1000}); I am not aware of any way to do this easily in Ember, as the standard JQuery $(document).ready() doesn't work with Ember apps. There has to be some easy way of doing this, but all of the other answers to this question seem to be like complex workarounds and are based on outdated versions of Ember.js.

问题 See http://jsfiddle.net/gazmcghee/v6PSA/. Clicking the link shows an alert. But changing the version of EmberJS under "Manage Resources" to https://github.com/downloads/emberjs/ember.js/ember-1.0.pre.js causes the link to disappear. How do I fix this ? 回答1: In the EmberJS version 0.9.8.1, Handlebars was included by default in Ember. Its not the case with the 1.0pre version, so you have to manually add it. PS: Don't forget to add Add.initialize() , or you will see unexpected behaviour. Here is

问题 So I do want to say that I've been searching for the answer for this and I've also tried to console.log my req.body post form and I keep getting undefined. So I feel that I'm losing the data from the form I send, I'm not sure what I"m doing wrong. So time to show some code.

问题 I'm trying to attach a typeahead to a text input in one of my templates. Because Ember use's handlebars, jQuery's document ready function is not the place for the typeahead definition. Where is the proper place to put "template ready" code? I tried a controller but there was no response from the typeahead. I don't think the template was rendered yet. App.PersonController = Ember.ObjectController.extend({ isEditing: false, init: function(){ this._super(); $('.example-films .typeaheadcx')

问题 I am interested in doing some conditional formatting and thought that the nicest way would be to do something like: Inside the CSS document {{#if something }} /* some css */ {{else}} /* some other css */ {{/if}} But I've searched a bit and only found Django related stuff. Is this possible in handlebars or any other js library? Note : I use Meteor . 回答1: Not natively in CSS, no.
