Question

我想使用创建日期对邮件进行分组。但是，如果我应用过滤器，我收到错误未知提供者：groupByFilterProvider＆lt; - groupByFilter

我希望我的结果按时间分组，例如，

下午1:24

您好你好

等。

但是，我在没有使用groupBy过滤器的情况下得到了这个。嗨1:24 PM 你好，下午1:24就好了。

我为此创造了一个小提琴，请仔细研究并建议我解决这个问题。 https://jsfiddle.net/Lt7aP/4/

我用过

groupBy: 'created'

Answer 1

groupBy不是开箱即用的AngularJS，你需要https://github.com/a8m/angular-filter#groupby

这里是代码，但是您必须截断数组的created成员，因为groupBy会将它们视为不同的值。我在控制器的末尾已经这样做了

＆＃13;

var myApp = angular.module('myApp', ['angular.filter','a8m.group-by']);

myApp.controller('LoginController', function($scope, $filter) {
  $scope.map = {
    "Today": [{
      "msg": "jhyhj",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472541041844,
      "from": "Dev"
    }, {
      "msg": "jghjg",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472541043213,
      "from": "Dev"
    }, {
      "msg": "hii",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472543443842,
      "from": "Dev"
    }, {
      "msg": "hii",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472543481505,
      "from": "Dev"
    }, {
      "msg": "hello",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472548350369,
      "from": "Dev"
    }, {
      "msg": "hello",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472548351702,
      "from": "Dev"
    }, {
      "msg": "hello",
      "userId": "800",
      "profileImagePath": "",
      "created": 1472548353023,
      "from": "Dev"
    }]
  };
  angular.forEach($scope.map["Today"],function(val,idx){
    val.created = $filter('date')(val.created, 'shortTime')
  });
});
