只有AngularJS UI路由器$状态重装子状态 [英] AngularJS UI Router $state reload child state only

问题描述

我使用的UI路由器为各州（用户）中的一个内链接主菜单，以及标签。用户州有一个用户列表，并单击用户时，我想只有重装孩子的状态，但它无论重装子状态和父状态（用户）。

I am using UI router for tabs of a main menu as well as for links within one of the states (users). The users state has a list of users and when a user is clicked, I want to reload the child state only, but it is reloading both the child state and the parent state (users).

下面是我的code：

    app.config(function ($stateProvider, $locationProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise("/");
    $locationProvider.html5Mode(true);
    $stateProvider
        .state('home', {
            abstract: true,
            template: '<div ui-view=""></div>',
            controller: 'HomeController as homeCtrl'
        })
        .state('users', {
            parent: 'home',
            url: '/users',
            templateUrl: '/User/Index',
            controller: 'UserController as userCtrl',
        })
        .state('users.createUser', {
            templateUrl: '/User/CreateUser',
            controller: 'CreateUserController as cuCtrl'
        })
        .state('users.editUser', {
            templateUrl: '/User/EditUser',
            controller: 'EditUserController as euCtrl',
            resolve: {
                userInfo: function (contextInfo, userData) {
                    return userData.get(contextInfo.getUserKey());
                }
            }
        })
        .state('users.addWebItemsForUser', {
            templateUrl: '/User/AddWebItemsForUser',
            controller: 'UserWebItemsController as uwiCtrl'
        })
        .state('users.addReportsForUser', {
            templateUrl: '/User/AddReportsForUser',
            controller: 'UserReportsController as urCtrl'
        })
        .state('users.userGroups', {
            templateUrl: '/User/UserGroups',
            controller: 'UserGroupController as userGroupCtrl'
        })
        //.state('users.logInWebApp', {
        //    template: '<h3>Logging into web app</h3>',
        //    resolve: {
        //        user: function() {
        //            return {
        //                //companyId: contextInfo.getCustomerKey()
        //                //userId:
        //                //password:
        //            }
        //        }
        //    },
        //    controller: function() {
        //        // need company code, username and password of user then need to open window with webapp url (will that work?) - do we still want to add this functionality?
        //    }
        //})
        .state('links', {
            url: '/links',
            templateUrl: '/Link/Index',
            controller: 'LinkController as linkCtrl'
        })
        .state('onlrpts', {
            url: '/onlineReports',
            templateUrl: '/OnlineReport/Index',
            controller: 'OnlineReportController as onlRptCtrl'
        })
        .state('reports', {
            url: '/customerReports',
            templateUrl: '/CustomerReport/Index',
            controller: 'CustomerReportController as custRptCtrl'
        });
})
.config(function($provide) {
    $provide.decorator('$state', function($delegate, $stateParams) {
        $delegate.forceReload = function() {
            return $delegate.go($delegate.$current.name, $stateParams, {
                reload: true,
                inherit: false,
                notify: true
            });
        };
        return $delegate;
    });
});

这是我父控制器（UserController的）功能被点击一个用户时被调用：

This is the function in my parent controller (UserController) that is called when a user is clicked:

            this.userTreeClick = function(e) {
        contextInfo.setUserKey(e.Key);
        contextInfo.setUserName(e.Value);
        userCtrl.userKey = e.Key;
        $state.forceReload();
    };

所以说，我是在users.userGroups状态，当我点击其他用户，我想只有users.userGroups状态重新加载。这可能吗？我已经看过在计算器通过谷歌和这里的答案，但我没有发现任何东西，这正是像什么，我试图做的。当我打破了检查$ $状态current.name - 名字是正确的 - users.userGroups，但一切都重新加载，而不是仅仅子状态。任何帮助是非常AP preciated！

So say I was in the users.userGroups state, when I click on another user, I want only the users.userGroups state to be reloaded. Is this possible? I have looked for an answer via Google and here at StackOverflow, but I haven't found anything that is exactly like what I am trying to do. When I break to check the $state.$current.name - the name is correct - users.userGroups, but it reloads everything instead of just the child state. Any help is very much appreciated!

推荐答案

本机，内置的 UI路由器的功能是：

The native, built-in functionality of ui-router is:

的形成一个孩子状态到另一个状态子的父是永远不会重新加载

除非我们明确地将改变这种内置的行为，例如通过装饰像你一样，迫使重装与传递这些选项：

unless we will explicitly change that built in behaviour, e.g. via decorator as you did and force the reload with passing these options:

• {重载：真的， 继承：假的，通知：真正}

• { reload: true, inherit: false,notify: true }

解决方法：不要强迫的重新加载 - 而不是用一些参数为每一个孩子的（如的groupId ）的

Solution: do not force reload - instead use some Parameter for each child (e.g. groupId)

.state('users.userGroups', {
        templateUrl: '/User/UserGroups/:groupId', // here is the groupId param defined
        controller: 'UserGroupController as userGroupCtrl'
    })

然后，如果导航到不同的组 - 不同的参数：的groupId将触发重载只是状态

Then, if navigating to a different group - the different parameter :groupId will trigger reload just of that state.

一个方法甚至可以是过往一些虚拟的参数，其值为null或...的String.Empty这样的URL没有改变。我试图表明，在这里：

One way could even be the passing some dummy param, which has value null or string.empty... so the url is not changing. I tried to show that here:
