目前,我将状态网址定义为:
... /:表/编辑/:ID 的
- >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;
}])
