Angularjs排序依据的NG-重复不起作用 [英] Angularjs OrderBy on ng-repeat doesn't work

问题描述

我想使用AngularJS我的第一个项目（一个赛事经理）和 NG-重复排序依据过滤器$ C>不工作:(我读过所有关于那个的文档，但没有做：/

I'm trying to use AngularJS for my first project (a tournaments manager) and the orderBy filter on ng-repeat doesn't work :( I have read all the documentation about that, but nothing to do :/

所以，我对 $范围定义瓦尔这样的：

$scope.order_item = "count_win";
$scope.order_reverse = false;
$scope.teams = {
  100 : {
    id: 100,
    name: "XXX",
    count_win: 1,
    count_loose: 2,
    goal_average: 1,
  },
  200 : {
    id: 200,
    name: "XXX",
    count_win: 1,
    count_loose: 2,
    goal_average: 1,
  },
  [...]
};

现在，在我看来我试图重新排序（第一只有一个订单项目），但从来没有工作...

Now, on my view i'm trying to reorder (first with only one order item) but never work...

<tr ng-repeat="team in teams | orderBy:order_item:order_reverse">
   <td>{{team.name}}</td>
   <td>{{team.count_loose}}</td>
   <td>{{team.goal_average}}</td>
</tr>

第二次，我想从2条信息来重新排序： count_win 和 goal_average 如果第一个是平等的..我尝试更换 $ scope.order_item 这样的，但如果有一个code没有工作，他绝不会与2工作...

The second time, I want to reorder from 2 pieces of information: count_win and goal_average if first are equal.. I try to replace $scope.order_item like that, but if with one the code doesn't work, he'll never work with 2...

$scope.order_item = ['count_win','goal_average'];

感谢大家的阅读和遗憾的投递大小。

Thank you all for reading and sorry for the post size.

推荐答案

$ scope.teams 不是一个数组（这是对象的对象），以及排序依据过滤仅适用于数组。如果你 $ scope.teams 一个数组，它将工作：

$scope.teams isn't an array (it's an object of objects), and the orderBy filter only works with arrays. If you make $scope.teams an array, it will work:

$scope.teams = [
    {
      id: 100,
      name: "team1",
      count_win: 3,
      count_loose: 2,
      goal_average: 2,
    },
    {
      id: 200,
      name: "team2",
      count_win: 3,
      count_loose: 2,
      goal_average: 1,
    },        
    {
      id: 300,
      name: "team3",
      count_win: 1,
      count_loose: 2,
      goal_average: 1,
     }
];

或者，您可以添加一个特殊的过滤器上对象的作品，像这样（从这里借来的>）

app.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;
  };
});

和使用这样的：

<tr ng-repeat="team in teams | orderObjectBy:order_item:order_reverse">

请注意，这个自定义过滤器不会排序顺序数组作为你问题的第二部分工作。

Note that this custom filter will not work with an array of sort orders as in the second part of your question.
