Question

我有一个＆＃34;事件＆＃34;包含＆＃34; startDate＆＃34;的对象属性。我已经编写了一个自定义过滤器，＆＃34; happenToday＆＃34;，预计将返回一个事件数组，这些事件的startDate属性与＆＃34;今天＆＃34;匹配。过滤函数中定义的变量。下面的代码是我尝试测试自定义过滤器。没有显示任何事件，但有预期的匹配。控制台中也没有抛出任何错误。我错过了什么或误解了什么？谢谢。

JS：

var myApp = angular.module('myApp', []);


myApp.filter('occursToday', function () {
  return function (events) {
    var today = new Date('12/1/2014');
    var filtered = [];
    for (var i = 0; i < events.length; i++) {
      var evnt = events[i];
      if (evnt.startDate === today) {
        filtered.push(evnt);
      }
    }
    return filtered;
  };
});


myApp.controller('MainCtrl', function($scope){
    $scope.greeting = 'Hello world!';
    $scope.events = [
      {"name": "An Event", "venue": "A Park", "startDate": new Date('12/1/2014'), "startTime": new Date('12/1/2014'), "endDate": new Date('12/1/2014'), "endTime": new Date('12/1/2014'), "website": "www.example.org", "description":"Yada yada.", "details": "Blah blah."},
      {"name": "An Event", "venue": "A Park", "startDate": new Date('12/1/2014'), "startTime": new Date('12/1/2014'), "endDate": new Date('12/1/2014'), "endTime": new Date('12/1/2014'), "website": "www.example.org", "description":"Yada yada.", "details": "Blah blah."},
      {"name": "An Event", "venue": "A Park", "startDate": new Date('12/2/2014'), "startTime": new Date('12/2/2014'), "endDate": new Date('12/2/2014'), "endTime": new Date('12/2/2014'), "website": "www.example.org", "description":"Yada yada.", "details": "Blah blah."},
      {"name": "An Event", "venue": "A Park", "startDate": new Date('12/2/2014'), "startTime": new Date('12/2/2014'), "endDate": new Date('12/2/2014'), "endTime": new Date('12/2/2014'), "website": "www.example.org", "description":"Yada yada.", "details": "Blah blah."},
      {"name": "An Event", "venue": "A Park", "startDate": new Date('12/3/2014'), "startTime": new Date('12/3/2014'), "endDate": new Date('12/3/2014'), "endTime": new Date('12/3/2014'), "website": "www.example.org", "description":"Yada yada.", "details": "Blah blah."},
    ]
});

                </div>
              </div>
            </li>

          </ul>
        </div>

Answer 1

您可能需要使用

       evnt.startDate.getTime() === today.getTime()

为什么这个自定义Angular过滤器没有返回任何预期的匹配？
