Angular-ng-repeat order를 만들 수 없습니다.

Angular-ng-repeat order를 만들 수 없습니다.

---

orderBy로 ng-repeat의 많은 예를 시도했지만 json이 작동하도록 만들 수 없습니다.

<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>

그리고 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"
    }
}

내가 무엇을 쓰는지는 중요하지 않습니다. 나는 항상 같은 순서를 받거나 전혀 순서가 없다고 말할 수 있습니다.

는 orderBy단지 배열 작동 - 참조 http://docs.angularjs.org/api/ng.filter:orderBy을

또한 ng-repeat에서 Angularjs OrderBy @ Arrays 대신 객체에 사용할 훌륭한 필터가 작동하지 않습니다.

---

언급했듯이 배열 만 허용됩니다. 하지만 간단하게하기 위해 여기 https://gist.github.com/brev/3949705에서 볼 수 있듯이 파이핑 기능을 통해 객체를 배열로 동적으로 변환 할 수 있습니다.

필터를 선언하고 ng-repeat에 추가하십시오 :)

<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"}}

the built-in orderBy filter will no longer work when iterating an object. It’s ignored due to the way that object fields are stored. You need create a custom filter

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>

in Eike Thies's response above, if we use underscore.js, filter could be simplified to :

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

---

Here's a version of @Julian Mosquera's code that also supports sorting by object 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;
    };
});

You're going to have to reformat your releases object to be an array of objects. Then you'll be able to sort them the way you're attempting.

orderby works on arrays that contain objects with immidiate values which can be used as filters, ie

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

When the above array is repeated, you may use | orderBy:'favs' to refer to that value immidiately, or use a minus in front to order descending

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