问题 Is there a way to wait until a template is fully rendered before accessing its children through a view, using jquery for instance? didInsertElement doesn't seem to work as expected for me. I need to add an additional half second delay before the template is fully constructed. The template iterates over an array in the controller and creates several divs. it's these divs that aren't accessible immediately, even when I override didInsertElement. 回答1: I'm not aware of how you insert those

问题 With ember-data I'm loading all records of a model with: App.adapter = DS.Adapter.create({ findAll: function(store, type) { var url = type.url; jQuery.getJSON(url, function(data) { var ids = data.map(function(item, index, self){ return item.id }); store.loadMany(type, ids, data); }); } }); The didLoad method is called when each of the record has finished loading. Is there a method to call when all records have finished loading? EDIT Model: App.Article = DS.Model.extend({ title: DS.attr(

问题 I have a RecordArray that has come back from a App.ModelName.find(). I'd like to do some things with it, like: paginating through the set of records within adding records from another findQuery into the array I may be confused, but it seems like it's difficult (or at least undocumented) on how to work with the records that come back from find()/findAll()/findQuery() other than looping over the set and displaying them as normal. This is further complicated by the array that gets returned from

问题 I've figured out that I can clone an Ember Data record and copy its Attributes, but none of the belongsTo / hasMany relationships are cloned. Can I do this somehow if I don't know what relationships would be possible, going off of the relationships that exist? For reference, here is what I've got that will clone an Ember Data record's attributes: var attributeKeys = oldModel.get('constructor.attributes.keys.list'); var newRecord = this.get('store').createRecord(oldModel.constructor.typeKey);

问题 I have a ArrayController for date picker with properties to and from . Now when user selects a new date range from the UI both to and from value changes. So a function which observers on to and from is trigger twice for a single change in date range. I want to trigger the function only one every date range change. Any suggestions how to do that with ember app = Ember.Application.create(); app.Time = Ember.ArrayController.create({ to: null, from: null, rootElement: "#time", debug1: function()

问题 I want a computed property to observe a non-ember global: a specific key in localStorage. Is this possible? The following does not seem to cut it: someProperty:function(){ //some functionality }.property('localStorage.someKey') Is it possible to do what I'm trying to do directly? 回答1: In general, you can observe regular JavaScript objects just fine. You just need to use Ember.get and Ember.set to modify them: var pojo = {}; var MyObject = Ember.Object.extend({ bigEyeballs: function() { var O
