限制与AngularJS状态匹配的动态URL参数的最佳方法

标签: javascript angularjs url-routing url-parameters

目前,我将状态网址定义为:
... /:表/编辑/:ID
- >因此,两个网址:
... / products / edit / 5 &的 ... / notValidTable /编辑/ 5 按以下定义加载我的tableEdit状态:


tableEdit.state.js:

angular.module(‘myApp')

.config(function($stateProvider) {

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

问:我知道tableEdit中的'table'参数应该只是以下之一:'产品','提供商','客户','关键字'或“主题”,如何限制其状态可以加载的值?

这是我的解决方案,但我希望能够提供反馈或更好地解决这个问题:

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' s表格的可能值:table'参数,以便我的页面被适当地重定向为无效的参数值?

非常感谢。

您可以在路线参数上加上正则表达式。这是一个有效的例子:



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;
}])
