javascript – Emberjs使用sortProperties按日期排序内容

我试图使用Emberjs sortProperties在这个jsfiddle中按日期排序内容.我的模型有一个startTime属性,我试图排序但它不起作用.然后我在控制器中创建了一个名为todayEvent的计算属性,该属性返回与传入日期匹配的事件,我尝试对其进行排序,但它也无效.我所要做的就是列出在同一天发生的事件,但是以chich事件中发生的一天中的时间按照升序排序,例如,在早上10点之前发生的事件应该在下午12点之前列出.

这是jsfiddle

该模型：

App.TimeSlot = DS.Model.extend( {
  startTime: DS.attr('date'),
  endTime: DS.attr('date'),
  allDay: DS.attr('boolean'),
  soldOut: DS.attr('boolean')
});

控制器

App.TimeSlotController = Ember.ArrayController.extend({
 content: [ ],

 sortProperties: ['todayEvent'],
 sortAscending: true,

 day: Ember.A(['2013-10-25']),

 todayEvent: function(){
  self = this;
  u = self.get('content'); 
  console.log('u', u);
  kl =  u.filter(function(availableSlot) {
   console.log ('a', availableSlot.get('startTime') );

 return (moment(availableSlot.get('startTime')).format("YYYY-MM-DD") ==  self.get('day').toString() );
  }); 

   return kl;  
 }.property('day', 'content@each'),


});

fixtureAdapter

App.TimeSlot.FIXTURES = [

  {
    id: 3,
    startTime: moment.utc('2013-10-25T12:30:00+01:00',"YYYY-MM-DD HH:mm:ss" ),    
    allDay: true
  },

 {
   id: 4,
   startTime: moment.utc('2013-10-25T10:10:00+01:00',"YYYY-MM-DD HH:mm:ss" ),    
   allDay: true
},

 {
  id: 5,    
  startTime: moment.utc('2013-10-23 00:00 +01:00', "YYYY-MM-DD HH:mm"),    
  allDay: true
 }
];

解决方法:

我设法解决了@edu,但感谢您的帮助.你可以看到工作jsfiddle.

有两种方法,都使用Ember.computed.sort：

 sortedTime: Ember.computed.sort('todayEvent',       function(a, b){

    if (
      moment(Ember.get(a, 'startTime') ) >  moment(Ember.get(b, 'startTime') ) 
    ){

   //returns morning timings before afternoon timings
   //api doc says return 1 when 'a' should come after 'b'
   //http://emberjs.com/api/#method_computed_sort

   return 1;

   } else if ( 
      moment(Ember.get(a, 'startTime') ) <   moment(Ember.get(b, 'startTime') ) 
   )
   {
    //returns afternoon timings before morning timings
   //api docs says return -1, when 'a' should come before 'b'
    return -1;
   }
     return 0;

  })

第二种方法

  //adapted from http://jsbin.com/OjoXOqE/9/edit

  sortedContent: Ember.computed.sort('content.@each.startTime', function(a, b){

    //the this keyword does not work here, 
    //throws "Object #<Object> has no method 'get'"
    //so we use the Ember keyword to get it working

   var ap = moment(Ember.get(a, 'startTime')),
       bp = moment(Ember.get(b, 'startTime'))

  //we return morning before afternoon times 
    if(ap !== bp) {
      return ap - bp;
    }

  })
