Angular-ng-repeat orderBy workを作成できません

私はorderByでng-repeatの多くの例を試しましたが、jsonをそれで動作させることはできません。

<div ng-app>
    <script type="text/javascript" src="http://code.angularjs.org/1.0.1/angular-1.0.1.js"></script>
    <div ng:controller="Main">
        <div ng-repeat="release in releases| orderBy:'environment_id'">      
            {{release.environment_id}}
        </div>
    </div>
</div>

そして、JSON

function Main($scope) {
$scope.releases = {
    "tvl-c-wbap001 + tvl-webapp": {
        "timestamp": " 05:05:53 PM ",
        "environment_id": "CERT5",
        "release_header": "Projects/Dev",
        "date": "19 Oct",
        "release": "12.11.91-1"
    },
    "tvl-c-wbap401 + tvl-webapp": {
        "timestamp": " 10:07:25 AM ",
        "environment_id": "CERT4",
        "release_header": "Future Release",
        "date": "15 Oct",
        "release": "485-1"
    },
    "tvl-c-wbap301 + tvl-webapp": {
        "timestamp": " 07:59:48 AM ",
        "environment_id": "CERT3",
        "release_header": "Next Release",
        "date": "15 Oct",
        "release": "485-1"
    },
    "tvl-c-wbap201 + tvl-webapp": {
        "timestamp": " 03:34:07 AM ",
        "environment_id": "CERT2",
        "release_header": "Next Changes",
        "date": "15 Oct",
        "release": "13.12.3-1"
    },
    "tvl-c-wbap101 + tvl-webapp": {
        "timestamp": " 12:44:23 AM ",
        "environment_id": "CERT1",
        "release_header": "Production Mirror",
        "date": "15 Oct",
        "release": "13.11.309-1"
    },
    "tvl-s-wbap002 + tvl-webapp": {
        "timestamp": " 12:43:23 AM ",
        "environment_id": "Stage2",
        "date": "15 Oct",
        "release": "13.11.310-1"
    },
    "tvl-s-wbap001 + tvl-webapp": {
        "timestamp": " 11:07:38 AM ",
        "environment_id": "Stage1",
        "release_header": "Production Mirror",
        "date": "11 Oct",
        "release": "13.11.310-1"
    },
    "tvl-p-wbap001 + tvl-webapp": {
        "timestamp": " 11:39:25 PM ",
        "environment_id": "Production",
        "release_header": "Pilots",
        "date": "14 Oct",
        "release": "13.11.310-1"
    },
    "tvl-p-wbap100 + tvl-webapp": {
        "timestamp": " 03:27:53 AM ",
        "environment_id": "Production",
        "release_header": "Non Pilots",
        "date": "11 Oct",
        "release": "13.11.309-1"
    }
}

何を書いても構いません。いつも同じ注文を受け取るか、注文しないと言うかもしれません。

orderByは配列でのみ機能します- http://docs.angularjs.org/api/ng.filter:orderBy を参照してください

また、配列の代わりにオブジェクトに使用する優れたフィルター@ ng-repeatのAngularjs OrderByは機能しません

前述のように、配列のみが許可されます。しかし、簡単にするために、ここに見られるように、パイピング関数を介してオブジェクトを動的に配列に変換できます https://Gist.github.com/brev/3949705

フィルターを宣言し、ng-repeatに追加するだけです:)

<div ng-app="myApp">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-controller="Main">
  <div ng-repeat="release in releases | object2Array | orderBy:'environment_id'">{{release.environment_id}}</div>
</div>

<script>

var app = angular.module('myApp', []).filter('object2Array', function() {
    return function(input) {
      var out = []; 
      for(i in input){
        out.Push(input[i]);
      }
      return out;
    }
  })
.controller('Main',function ($scope) {
        $scope.releases = {"tvl-c-wbap001 + tvl-webapp":{"timestamp":" 05:05:53 PM ","environment_id":"CERT5","release_header":"Projects/Dev","date":"19 Oct","release":"12.11.91-1"},"tvl-c-wbap401 + tvl-webapp":{"timestamp":" 10:07:25 AM ","environment_id":"CERT4","release_header":"Future Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap301 + tvl-webapp":{"timestamp":" 07:59:48 AM ","environment_id":"CERT3","release_header":"Next Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap201 + tvl-webapp":{"timestamp":" 03:34:07 AM ","environment_id":"CERT2","release_header":"Next Changes","date":"15 Oct","release":"13.12.3-1"},"tvl-c-wbap101 + tvl-webapp":{"timestamp":" 12:44:23 AM ","environment_id":"CERT1","release_header":"Production Mirror","date":"15 Oct","release":"13.11.309-1"},"tvl-s-wbap002 + tvl-webapp":{"timestamp":" 12:43:23 AM ","environment_id":"Stage2","date":"15 Oct","release":"13.11.310-1"},"tvl-s-wbap001 + tvl-webapp":{"timestamp":" 11:07:38 AM ","environment_id":"Stage1","release_header":"Production Mirror","date":"11 Oct","release":"13.11.310-1"},"tvl-p-wbap001 + tvl-webapp":{"timestamp":" 11:39:25 PM ","environment_id":"Production","release_header":"Pilots","date":"14 Oct","release":"13.11.310-1"},"tvl-p-wbap100 + tvl-webapp":{"timestamp":" 03:27:53 AM ","environment_id":"Production","release_header":"Non Pilots","date":"11 Oct","release":"13.11.309-1"}}
    });

組み込みのorderByフィルターは、オブジェクトを反復するときに機能しなくなります。オブジェクトフィールドの保存方法により無視されます。カスタムフィルターを作成する必要があります

yourApp.filter('orderObjectBy', function() {
  return function(items, field, reverse) {
    var filtered = [];
    angular.forEach(items, function(item) {
      filtered.Push(item);
    });
    filtered.sort(function (a, b) {
      return (a[field] > b[field] ? 1 : -1);
    });
    if(reverse) filtered.reverse();
    return filtered;
  };
});

<ul>
<li ng-repeat="item in items | orderObjectBy:'color':true">{{ item.color }}</li>
</ul>

上記のEike Thiesの応答で、underscore.jsを使用する場合、フィルターは次のように簡略化できます。

var app = angular.module('myApp', []).filter('object2Array', function() {
  return function(input) {
    return _.toArray(input);
  }
});

これは、オブジェクトによるソートもサポートする@Julian Mosqueraのコードのバージョンですkey：

yourApp.filter('orderObjectBy', function () {
    return function (items, field, reverse) {
        // Build array
        var filtered = [];
        for (var key in items) {
            if (field === 'key')
                filtered.Push(key);
            else
                filtered.Push(items[key]);
        }
        // Sort array
        filtered.sort(function (a, b) {
            if (field === 'key')
                return (a > b ? 1 : -1);
            else
                return (a[field] > b[field] ? 1 : -1);
        });
        // Reverse array
        if (reverse)
            filtered.reverse();
        return filtered;
    };
});

orderbyは、フィルターとして使用できる、immidiate値を持つオブジェクトを含む配列で機能します。つまり、

controller.images = [{favs:1,name:"something"},{favs:0,name:"something else"}];

上記の配列が繰り返される場合、|を使用できます。 orderBy： 'favs'はその値を即座に参照するか、前にマイナスを使用して降順で並べます

<div class="timeline-image" ng-repeat="image in controller.images | orderBy:'-favs'">
    <img ng-src="{{ images.name }}"/>
</div>

リリースオブジェクトをarrayのオブジェクトになるように再フォーマットする必要があります。次に、あなたがしようとしている方法でそれらを並べ替えることができます。
