无法调用 uiCanExit - angular ui router 1.0.0 beta [英] unable to invoke uiCanExit - angular ui router 1.0.0 beta
问题描述
我在 components/app/app-routes.js 中有以下路由文件:
I have the following routes file in components/app/app-routes.js:
export default
function AppRoutes($stateProvider, $urlRouterProvider, $transitionsProvider) {
'ngInject';
// reference: https://ui-router.github.io/guide/ng1/migrate-to-1_0#lazy-resolves
const defaultResolvePolicy = {
when: 'EAGER'
};
const STATES = [{
name: 'logout',
url: '/logout?applicationName&desktopName&sn',
}, {
name: 'base',
url: '',
abstract: true,
template: '<ui-view></ui-view>'
}, {
name: 'app',
parent: 'base',
abstract: true,
component: 'wireApp',
data: {
authRequired: true
},
resolvePolicy: defaultResolvePolicy,
resolve: {
labels(LabelService) {
'ngInject';
return LabelService.fetch();
},
settings(SettingsService) {
'ngInject';
return SettingsService.fetch();
},
}
}, {
name: '404',
url: '/404',
parent: 'base',
template: '<w-404></w-404>',
resolvePolicy: defaultResolvePolicy,
resolve: {
module($q, $ocLazyLoad) {
'ngInject';
return $q((resolve) => {
require.ensure([], (require) => {
let mod = require('pages/404');
$ocLazyLoad.load({
name: mod.name
});
resolve(mod.name);
}, '404');
});
},
}
}, {
name: 'dashboard',
parent: 'app',
url: '/dashboard',
data: {
authRequired: true
},
views: {
'content@app': {
template: '<w-dashboard priority-tasks="$resolve.priorityTasks"></w-dashboard>'
},
},
resolvePolicy: {
module: defaultResolvePolicy,
priorityTasks: {
when: 'LAZY'
},
},
resolve: {
priorityTasks($http, $q, CacheFactory, CustomerService, RuntimeConfig, PermissionService) {
'ngInject';
if (!CacheFactory.get('priorityTasks')) {
CacheFactory.createCache('priorityTasks', {
storageMode: 'sessionStorage',
storagePrefix: 'w'
});
}
const priorityTasksCache = CacheFactory.get('priorityTasks');
if (PermissionService.check('PRIORITY_TASKS', 'view')) {
return $http.get(`${RuntimeConfig.DEV_API_URL}/customer/${CustomerService.model.currentCustomer.id}/priority-tasks`, {
cache: priorityTasksCache
}).then(({
data
}) => data, () => $q.resolve([]));
}
return [];
},
module($q, $ocLazyLoad) {
'ngInject';
return $q((resolve) => {
require.ensure([], (require) => {
let mod = require('pages/dashboard');
$ocLazyLoad.load({
name: mod.name
});
resolve(mod.name);
}, 'dashboard');
});
}
}
}, {
name: 'loans',
parent: 'app',
url: '/loans',
data: {
authRequired: true
},
views: {
'content@app': {
template: '<w-loans></w-loans>',
},
},
resolvePolicy: defaultResolvePolicy,
resolve: {
security($q, $state) {
'ngInject';
//irl get this from a service.
console.log($transitionsProvider, "TRANSISIONS PROVIDER FROM ROUTE");
// let permissions = false;
// if (!permissions) {
// return $q.reject("No permissions");
// }
},
module($q, $ocLazyLoad) {
'ngInject';
return $q((resolve) => {
require.ensure([], (require) => {
let mod = require('pages/loans');
$ocLazyLoad.load({
name: mod.name
});
resolve(mod.name);
}, 'loans');
});
}
}
}];
$urlRouterProvider
.when('', '/dashboard')
.when('/', '/dashboard')
.when('/login', '/dashboard')
.otherwise('/404');
//this will redirect all rejected promises in routes to a 404.
$transitionsProvider.onError({
to: '*',
from: '*'
}, (transition) => {
let $state = transition.router.stateService;
$state.go('404');
});
STATES.forEach((state) => {
$stateProvider.state(state);
});
}
在我的贷款控制器(上面的关联状态，贷款")中，但是，我无法访问新的 uiCanExit 回调.:
in my loans controller (associated state above, 'loans'), however, I am unable to access the new uiCanExit callback.:
.component('wLoans', {
template: require('./loans.html'),
controller: LoansController,
bindings: {
settings: '<',
labels: '<'
}
});
function LoansController($window, $timeout, $http, $compile, $log, $filter, LoansService, ConfigService, ngDialog, SettingsService, CustomerService, ColumnRenderService, $transitions) {
'ngInject';
this.uiCanExit = function () {
console.log("WHY AM I NOT GETTING HERE");
}
}
当我在状态之间切换时，控制台中什么也没有出现，我试图弄清楚当我在状态之间切换时如何运行 uiCanExit 生命周期钩子(特别是 dashboard和贷款)
nothing appears in the console when I switch between states, and I'm trying to figure out what to do to get the uiCanExit lifecycle hook to be run when I switch in between states (particularly dashboard and loans)
推荐答案
我对此不太确定，但问题可能是由于未直接引用组件造成的吗?可能这仅在您通过 component 键引用您的 loans 组件而不是将它们放置在呈现组件的 template 中时才有效.我假设在你的情况下，路由器试图在(未声明的，因此是虚拟的)控制器中找到回调，而不是使用组件的控制器.
I'm not sure about this, but could the problem be caused by not referencing the component directly? Probably this only works when you reference your loans component via the component key instead of placing them in a template which renders the component. I assume that in your case the router tries to find the callback in the (not declared and thus dummy) controller instead of using the component's controller.
请查看文档:https://ui-router.github.io/docs/latest/interfaces/ng1.ng1controller.html#uicanexit
您可以通过将带有 uiCanExit() 方法的 controller 实现置于您的 loans 状态来验证此假设.
You can validate this assumption by putting a controller implementation with the uiCanExit() method in your loans state.
