我正在使用Angular 1.5.6,正在使用AngularUI路由器(https://github.com/angular-ui/ui-router)。我有不同的路线,例如客户和用户。在每个类别中都有不同的“子根”,例如一个用于列表,一个用于edt。我在这里设置客户路线:
import customerListModule from './list/customer.list';
import customerServiceModule from './services/customer.service';
...
...
function customerModule($stateProvider, $urlRouterProvider) {
'ngInject';
$urlRouterProvider
.when('/customer', ['$state', function($state) {
$state.go('customer.list.tracked');
}]);
$stateProvider
.state('customer', {
parent: 'root',
url: '/customer',
abstract: true,
views: {
'root@app': {
template: '<div class="customer" ui-view=""></div>'
}
},
onEnter: () => {
// in here I want to change my customer servce
},
})
.state('customer.list', {
url: '',
views: {
'@customer': {
template: '<customer></customer>'
}
},
breadcrumbs: {
name: 'customer.breadcrumbs.list'
},
params: {
saving: false
}
})
.state('customer.edit', {
parent: 'customer.list',
url: '/:id/edit',
views: {
'@customer': {
template: editTemplate(),
controller: manageCustomerCtrl,
controllerAs: 'manageCustomerVM'
}
},
breadcrumbs: {
name: 'customer.breadcrumbs.edit'
},
resolve: {
isAuthorized: 'readWriteAccess'
},
bodyClass: 'product-form'
});
}
export default angular.module('customerAdminUI.customer', [
'ui.bootstrap',
'ui.router',
customerListModule.name,
customerServiceModule.name,
...
...
])
.config(customerModule);
我有一个客户服务,要在客户状态的onEnter回调中访问。我试图将其注入到customerModule方法中,以便可以在onEnter()回调中使用它:
function customerModule($stateProvider, $urlRouterProvider, CustomerService) {
...
...
$stateProvider
.state('customer', {
parent: 'root',
url: '/customer',
abstract: true,
views: {
'root@app': {
template: '<div class="customer" ui-view=""></div>'
}
},
onEnter: () => {
CustomerService.clearSearch();
},
})
但是我得到了错误:
Unknown provider: CustomerService
如何在onEnter回调中使用服务?
最佳答案
我们可以要求提供服务作为参数
// not ready for minification
onEnter: function(CustomerService) {
CustomerService.dowhatneeded...
},
// preferred way
onEnter: ['CustomerService', function(service) {
service.dowhatneeded...
}],
