Angular过滤器嵌套分组

angularjsmultidimensional-arrayangular-filters

在嵌套数组中使用angular-filter模块的groupBy过滤器时出现问题。 "位置"未定义，而“颜色”没有输出任何内容。 我用别人的代码修改了此示例。

提前致谢！

您的数据结构与代码逻辑不对应。这段代码可以正常运行：

<!DOCTYPE html>
<html ng-app="app">
    <head>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.js"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-filter/0.4.7/angular-filter.js"></script>
        <script>
            angular.module('app',['angular.filter']).controller('MainController', function($scope) { 
            $scope.players = [
              {name: 'Gene',
                team: {location: 'texas',
                      color: 'blue'}
              },
              {name: 'George', team: {location: 'texas',
                        color: 'red'}},
              {name: 'Steve', team: 
                        {location: 'kansas',
                        color: 'purple'}},
              {name: 'Paula', team: 
                        {location: 'kansas',
                        color: 'green'}},
              {name: 'Scruath', team:
                        {location: 'kansas',
                        color: 'orange'}}
            ];
            });
        </script>
