该orderBy只适用于阵列-见http://docs.angularjs.org/api/ng.filter:orderBy

还有一个很好的过滤器用于对象而不是数组@Angularjs OrderBy on ng-repeat 不起作用

如前所述，只允许使用数组。但是为了让您更简单，您可以通过管道函数将对象动态转换为数组，如下所示 https://gist.github.com/brev/3949705

只需声明过滤器，并将其添加到 ng-repeat :)

<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"}}
    });
</script>

迭代对象时，内置的 orderBy 过滤器将不再起作用。由于对象字段的存储方式，它被忽略。您需要创建自定义过滤器

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>

在上面 Eike Thies 的回复中，如果我们使用 underscore.js，过滤器可以简化为：

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

这是@Julian Mosquera 代码的一个版本，它也支持按对象键排序：

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;
    };
});
