Question

我正在查看Durandal样本，试图了解路由的工作原理。

shell.js指定了这些路由：

{ route: ['', 'knockout-samples*details'], moduleId: 'ko/index', title: 'Details...', nav: true, hash: '#knockout-samples' },
{ route: 'view-composition',moduleId: 'viewComposition/index',  title: ...

knockout-samples下的

：

{ route: '', moduleId: 'helloWorld/index', title: 'Hello World', type: 'intro' },
{ route: 'helloWorld', moduleId: 'helloWorld/index', title: 'Hello World', type: intro', nav: true},

我想要实现的是helloWorld下的另一个层次结构。像这样的东西： enter image description here

我试过这个但没有运气：

{ route: '', moduleId: 'helloWorld/index', title: 'Hello World', type: 'intro' },
{ route: 'helloWorld*details', moduleId: 'helloWorld/index', title: 'Hello World',           type: 'intro',      nav: true, hash:'#knockout-samples/helloWorld'}

但是，这不起作用。

Durandal路由不支持此级别的导航吗？

Answer 1

在创建“孙子”或“曾孙子”或更深的子路由器时，诀窍是引用相对父路由器，而不是根路由器。要获取对父路由器的引用，请将包含父路由器的模块添加为“孙子”模块的依赖项。你可以无限期地嵌套这样的路由器。例如：

myModuleWithChildRouter.js

define(['plugins/router'],  //reference to durandal root router
    function(router) {         

           var _childRouter = router.createChildRouter();

          return { myNewChildRouter: _childRouter}
}

myModuleWithGrandchildRouter.js

define(['myModuleWithChildRouter'],  //reference to module with child router
    function(childRouterModule) {        

           var _grandChildRouter = childRouterModule.myNewChildRouter.createChildRouter();
          .....

}

希望有所帮助！

要获得多个导航级别，我正在这样做：

唯一可访问的路由器是根路由器，因此每次我创建子路由器时都可以访问子路由器，我将它存储在模块上。然后，当我想创建另一个级别时，我从模块中获取子路由器并调用createChildRouter。

define([], function () {
    return {
        root: null,
        level1: null,
        level2: null
    };
});

define(['plugins/router', 'routers'], function (router, routerContainer) {
    var childRouter = router.createChildRouter()
        .makeRelative({
            moduleId: 'viewmodels/companyplussplat',
            //fromParent: true
            route: 'company'
        }).map([
            { route: 'order/:orderID', moduleId: 'orderdetail', title: 'Order', nav: false },
            { route: 'order/:orderID*details', moduleId: 'orderdetailplussplat', title: 'Order plus splat', nav: false }
        ]).buildNavigationModel();

    routerContainer.level1 = childRouter;

    return {
        activate: function () {
            console.log("Activating company plus splat");
        },
        deactivate: function () {
            console.log("Deactivating company plus splat");
        },
        router: childRouter
    };
});

define(['plugins/router', 'routers'], function (router, routerContainer) {
    //debugger;
    var childRouter = routerContainer.level1.createChildRouter()
        .makeRelative({
            moduleId: 'orderteailplussplat',
            //fromParent: true
            route: 'company/order/:orderID'
        }).map([
            { route: 'orderline/:orderlineID', moduleId: 'orderlinedetail', title: 'Order line detail', nav: false },
        ]).buildNavigationModel();

    routerContainer.level2 = childRouter;

    return {
        activate: function (orderID) {
            console.log('Activating order detail for: '+ orderID +' plus splat');
        },
        deactivate: function () {
            console.log('Deactivating order detail plus splat');
        },
        router: childRouter
    };
});

我希望这会对你有所帮助。

我添加了孩子作为父路由器本身的引用。也许有点鬼鬼祟祟，但工作愉快：

顶级路由器

define(["plugins/router"], function (router) {
    // create the constructor
    var ctor = function() {
    };

    ko.utils.extend(ctor.prototype, {
        activate: function () {
            //var self = this;
            var map = router.makeRelative({ moduleId: "viewmodels" }).map([
                { route: "", moduleId: "index", title: "Overview", nav: true, hash: "#/", enabled: true },
                { route: "data*details", moduleId: "data/shell", title: "Data Loading", nav: true, hash: "#/data", enabled: false },
                { route: "reporting*details", moduleId: "reporting/shell", title: "Reporting", nav: true, hash: "#/reporting", enabled: true },
                { route: "query*details", moduleId: "query/shell", title: "Query", nav: true, hash: "#/query", enabled: true },
                { route: "login", moduleId: "login", title: "Login", hash: "#/login", state: "out" }
            ]);

            return map.buildNavigationModel()
                .mapUnknownRoutes("404")
                .activate();
        });

    });

    return ctor;
});

儿童路由器

define(["plugins/router"], function (router) {
    var childRouter = router.createChildRouter()
            .makeRelative({
                moduleId: "viewmodels/reporting",
                fromParent: true
            }).map([
                { route: "", moduleId: "index", title: "Reporting", nav: false, hash: "#/reporting" },
                { route: "standard", moduleId: "standard", title: "Standard Reports", nav: true, hash: "#/reporting/standard" },
                { route: "alert*details", moduleId: "alert/shell", title: "Alerts", nav: true, hash: "#/reporting/alert" }
            ]).buildNavigationModel();

    // for alerts
    router.child = childRouter;

    var vm = {
        router: childRouter
    };

    return vm;
});

孙子路由器

define(["plugins/router"], function (router) {
    var grandchildRouter = router.child.createChildRouter()
        .makeRelative({
            moduleId: "viewmodels/reporting/alert",
            fromParent: true
        }).map([
            { route: "", moduleId: "index", title: "Alerts", hash: "#/reporting/alert" },
            { route: ":id", moduleId: "case", title: "Alert Details", hash: "#/reporting/alert" }
        ]).buildNavigationModel();

    var vm = {
        router: grandchildRouter
    };

    return vm;
});

希望有所帮助。

如果您使用的是durandal 2.0，则可以设置子路由器。这将允许您在hello world下创建一个新路由器，您可以链接其视图中的子视图的其他信息。您可以在文档中查看这些内容，但请确保在视图中设置该路由器，以便在您点击路径时

 #helloworld/subview

你已经激活了helloworld
