限制与 AngularJS 状态匹配的动态 URL 参数的最佳方法

Best way to restrict dynamic URL parameters matched to an AngularJS state

目前我有一个状态 url 定义为:
…/:table/edit/:id
-> 因此 urls:
…/products/edit/5 & …/notValidTable/edit/5 加载我的table编辑状态,定义如下:


tableEdit.state.js:

angular.module(‘myApp')

.config(function($stateProvider) {

  $stateProvider
    .state('tableEdit', {
      url: '/:table/edit/:id',
      templateUrl: ‘../table_edit/table_edit.html',
      controller: 'TableEditCtrl'
    });
});

Q - 据我所知,我在 tableEdit 中的“:table”参数只能是以下之一:“产品”、“供应商”、“客户”、“关键字”或“ topics',如何限制我的状态接受的加载值?

这是我的解决方案,但我希望得到反馈或解决此问题的更好方法:

app.js:

angular.module(‘myApp', [
    'ui.router',
])

.config(
  ['$urlRouterProvider',
  function($urlRouterProvider) {

  $urlRouterProvider
    .when('/:table/edit/:id', ['$match', '$state',
        function($match, $state) {
        if ($match.table !== 'products' 
        && $match.table !== 'providers' 
        && $match.table !== 'customer' 
        && $match.table !== 'keywords' 
        && $match.table !== 'topics') { 

            $state.transitionTo('tablesHome'); 
       }  else { 
            $state.transitionTo('tableEdit', $match, true); }
       }
    }
  ])
  .otherwise('/home');
])

是否有更好的方法来限制 tableEdit 的“:table”参数的可能值,以便我的页面针对无效参数值进行适当的重定向?

非常感谢。

您可以在路由参数上放置一个正则表达式。这是一个工作示例:

var app = angular.module('myApp', [
    'ui.router',
])

app.config(['$urlRouterProvider', '$stateProvider', function($urlRouterProvider, $stateProvider) {
  $stateProvider
    .state('table', {
      // this is the important bit. 
      // it will restrict this route to only 'products' and 'customers
      url: '/{table:products|customers}' 
    })
    .state('table.edit', {
      url: '/edit/:id',
    template: "<h1>TABLE</h1>"
    })
    .state('home', {
      url: '/*path',  // special 'catch all route',
      template: "<h1>HOME</h1>"
  });
 
  $urlRouterProvider.otherwise('/home'); 
}]);

app.run(['$rootScope', '$state', function($rootScope, $state) {
  $rootScope.$state = $state;
}])
