使用浏览器后退时，Angular $location 不会更新

问题描述

限时删除！！

有人遇到过这种行为吗?关于它没有太多提及，其他帖子性质不同.这似乎与有关浏览器行为的文档不一致.

Has anyone run across this behaviour? There isn't much mentioned about it, and the other posts are different in nature. This appears to be inconsistent w/ documentation about browser behaviour.

用户访问时与浏览器同步网址

• 更改地址栏.
• 点击后退或前进按钮(或点击历史链接).
• 点击链接.

https://docs.angularjs.org/api/ng/service/$location#！

https://docs.angularjs.org/api/ng/service/$location#!

发生了什么:

• 加载页面 - 哈希更新 (http://localhost:9000/#/)
• 单击开始" - 通过函数更新 $location.$$path 以更新哈希并加载新视图 (http://localhost:9000/#/guide)
• 棘手！用户单击浏览器中的后退按钮，哈希更新回 http://localhost:9000/#/ 但进行调试告诉我 $location.$$path 仍然认为我们在 $location.$$path =/guide - 基于位置路径的逻辑不起作用.

• Load page - hash updates (http://localhost:9000/#/)
• Click 'Start' - update $location.$$path via function to update hash and load new view (http://localhost:9000/#/guide)
• Tricky! User clicks back-button in browser, hash updates back to http://localhost:9000/#/ but debug tells me $location.$$path still thinks we are at $location.$$path = /guide - logic based on location path doesn't work.

这是现场帮助调试的观察者:

This is a watcher to on location to help debug:

// listen for the event in the relevant $scope
$rootScope.$on('locationChange', function (event, data) {
    console.log(data);
});

//Call locationChange watch at anytime the page is loaded
$scope.$emit('locationChange', $location.$$path);

路线如下:

$routeProvider
    .when('/guide', {
        templateUrl: 'views/guide.html',
        controller: 'GuideController',
        controllerAs: 'guide'
    })
    .when('/', {
        templateUrl: 'views/about.html',
        controller: 'AboutCtrl',
        controllerAs: 'about'
    })
    .otherwise({
        redirectTo: '/'
    });

推荐答案

我是如何解决这个问题的:

How I solved this:

var pop = 0;

window.onpopstate = function(event) {
    if (document.location.pathname === '/' && pop > 1) {
        pop = 0;
        document.location = 'http://localhost:9000/';
    }
    pop++;
};
