我在表格中有以下数据:

data = [
  {id: 1, name: 'Manchester United', type: 'Soccer', featured: true, country: 'England'},
  {id: 2, name: 'Manchester City', type: 'Soccer', featured: false, country: 'England'},
  {id: 3, name: 'Dallas Mavericks', type: 'Basketball', featured: true, country: 'USA'},
  {id: 4, name: 'Indian Cricket Team', type: 'Cricket', featured: true, country: 'India'},
  {id: 5, name: 'Australian Cricket Team', type: 'Cricket', featured: false, country: 'Australia'},
  {id: 6, name: 'Los Angeles Lakers', type: 'Basketball', featured: true, country: 'USA'},
  {id: 7, name: 'Los Angeles Clippers', type: 'Basketball', featured: false, country: 'USA'}
];

我想在国家/地区添加一个下拉框。选择国家/地区应过滤表格,仅显示该国家/地区的体育赛事。

问题在于我无法在下拉列表中显示唯一的国家/地区。

请帮助......提前致谢。

过滤:来自ng-options and unique filter not displaying angular.js

选择部分: <select data-ng-model="countryModel" ng-options="dd.country as dd.country for dd in data | unique:'country'">

ng-repeat部分 <tr data-ng-repeat="dat in data | filter: countryModel" data-ng-style="set_color(dat)">
