禁止基于查询参数更改的UI路由器重新加载视图 [英] Suppress reloading of ui-router based view on query parameter change

问题描述

更新的问题

标题中的问题仍然存在-是否可以捕获?parameters并取消视图重新加载.

Question in title still stands - is it possible to catch ?parameters and cancel view reload.

原始问题: 我需要为应用程序添加锚点支持(主题的锚点).

Original question: I need to add anchor support for my application (anchors to topics).

这是我的距离:

angular.module('app.topics', [
    'ui.state',
    'ui.router',
    'restangular'
    'app.topics.controllers'
])
.config(function config($stateProvider) {
    $stateProvider.state('viewtopic', {
        url: '/topics/:slug?section',
        onEnter: function($stateParams) {
            // Works, as state has been reloaded.
            console.log('$stateParams', $stateParams);
        },
        resolve: {
            topic: function ($stateParams, Topic) {
                // Wrapper around Restangular. Returns promise.
                return new Topic().get($stateParams.slug);
            }
        },
        views: {
            'main': {
                controller: 'TopicCtrl',
                templateUrl: 'topics/templates/details.tpl.html'
            },
            'sidebar': {
                controller: 'SidebarCtrl',
                templateUrl: 'topics/templates/sidebar.tpl.html'
            }
        }
    });
});

angular.module('app.topics.controllers', [])
    .controller('TopicCtrl', function ($scope, topic, $rootScope, $location,
                                         $anchorScroll, $stateParams) {
        $scope.topic = topic;
        $scope.slug = $stateParams.slug;
        $scope.section = $stateParams.section;
        // ..

        $scope.$watch('$stateParams.section', function (newValue, newValue) {
            // Does not work.
            console.log('stateParams.section changed', newValue, newValue);
        });
    });

我的根本问题是，当我单击带有#/topics/slug-name?section=section-1的链接时，状态被完全重新加载，这又重新请求了Topic的数据.

My root issue is when I click on link with #/topics/slug-name?section=section-1, state is reloaded completely, which in turn re-requests data for Topic. How can one just "refresh" query parameters (and catch that event in controller) but don't reload state (to keep data loaded)?

编辑

对于我的问题，有一个非常简单的解决方案，但我没有注意到- 每个 AngularJS文档关于"Hashbang和HTML5模式"-可以通过$location.hash()访问最后的哈希，并且可以通过$anchorScroll()

For my issue there is a rather simple solution which I've failed to notice - per AngularJS documentation on "Hashbang and HTML5 Modes" - last hash is accessible via $location.hash() and scrolling can be initiated by $anchorScroll()

所以我当前的解决方案是:

So my current solution is:

在控制器中:

$scope.$watch('$location.hash', function () {
    _.defer($anchorScroll);
});

需要延迟，因为可能尚未解析内容并且没有ID.

Defer is needed because content may not be parsed yet and there are no id's.

在模板中，我只需要将目标设置为#/topics/slug-name#section-name.

In template I just had to set target to #/topics/slug-name#section-name.

推荐答案

您是否在路由定义中尝试过reloadOnSearch参数?

Have you tried reloadOnSearch parameter within routes definition?

{
    route:'/',
    resolve: {
        templateUrl:'template.html',
        reloadOnSearch: false
    }
},
