AngularJS:让 UI-Router 在没有 URL 的情况下工作 [英] AngularJS : Making UI-Router work without a URL

问题描述

我正在使用 Angular UI 路由器创建一个主从页面.我已经能够使它工作 - 当我单击主记录时，此记录的 ID 会附加到 URL 并且详细视图显示此记录的详细信息.但是我有两个问题:

I am creating a master-detail page using the Angular UI router. I have been able to make it work - when I click on a master record, the id of this record is appended to the URL and the detail view shows the detail for this record. However I have two questions:

1. 是否可以在不更改 URL 的情况下完成这项工作?据我了解，UI 路由器是关于状态更改的，不一定是 url 更改.但是，如果我从路由器状态中删除 url 属性，则不会显示详细信息.
2. 与我的详细信息状态关联的模板是一个指令.目前该指令使用 $stateParams 获取主记录的 id.这使得它依赖于 UI 路由器.是否可以使用隔离范围传递此 ID?

1. Is it possible to make this work without a change in the URL? As I understand it the UI router is all about state changes, not necessarily url changes. However, if I remove the url property from the router state, then detail doesn't show up.
2. The template associated with my detail state is a directive. Currently this directive gets the id of the master record using $stateParams. This makes it dependent on the UI router. Is it possible to pass this id down using isolate scope?

这是我的代码的关键部分:

Here's are the key pieces of my code:

路由器配置如下:

$stateProvider
    .state('orderdetail', {
        url: '/orders/:id',
        template: '<my-order-detail></my-order-detail>'
    });
}

正如上面#1 中提到的，如果我注释掉 url，那么详细信息将停止出现.为什么?有没有办法在不更改 URL 的情况下完成这项工作?

As mentioned in #1 above, if I comment out the url, then detail stops appearing. Why? Is there a way to make this work without having the URL to change?

选择主记录后，我将状态更改如下:

When the master record is selected I change the state as follows:

$state.go('orderdetail', {
    id: vm.selectedOrderId
});

这是显示详细信息的指令的代码:

Here's the code for the directive that shows the detail:

angular.module('app.orderdetail', []);

angular.module('app.orderdetail')
    .directive('myOrderDetail', orderDetailDirective)
    .controller('OrderDetailController', OrderDetailController);

// ----- orderDetailDirective -----
orderDetailDirective.$inject = [];

function orderDetailDirective() {

    var directive = {
        restrict: 'E',
        templateUrl: 'components/orderdetail/orderdetail.html',
        scope: {
            id: '='
        },
        controller: 'OrderDetailController',
        controllerAs: 'vm'
    };

    return directive;
}

// ----- OrderDetailController -----
OrderDetailController.$inject = ['$stateParams'];

/* @ngInject */
function OrderDetailController($stateParams) {
    var vm = this;
    vm.id = $stateParams.id;
}

请注意，控制器使用 $stateParams 捕获所选主记录的 id.我很想通过切换到隔离范围来删除指令中的这种依赖关系.因此，与 UI 路由器状态关联的模板应如下所示:

Note that the controller captures the id of the selected master record using $stateParams. I would love to remove this dependency in the directive by switching to isolate scope. So the template associated with the UI router state should look something like this:

template: '<my-order-detail data-id={{vm.id}}></my-order-detail>'

这可能吗?

推荐答案

如果我确实理解您的目标，我们可以使用这个 template，通过 id 到指令 (及其隔离范围).

In case, I do understand your goal correctly, we can have this template, passing the id into directive (and its isolated scope).

有一个工作的plunker

$stateProvider
    .state('orderdetail', {
      url: '/orders/:id',
      //template: '<my-order-detail></my-order-detail>',
      template: '<my-order-detail data-id="$stateParams.id"></my-order-detail>',
    });

刚刚将其添加到我们的代码中(所以我们不需要控制器，$stateParams 已经在每个视图状态模板的范围内):

Just added this to our code (so we do not need controller, $stateParams are already in scope of each view state template):

.run(['$rootScope', '$state', '$stateParams',
    function($rootScope, $state, $stateParams) {
      $rootScope.$state = $state;
      $rootScope.$stateParams = $stateParams;
    }
])

这就是它的名字

<a ui-sref="orderdetail({id:1})">
<a ui-sref="orderdetail({id:2})">
