Angularjs：为什么页面刷新销毁$ rootScope的值？ [英] Angularjs: Why page refresh destroy the values of $rootScope?

问题描述

在我的本地路由 http：// localhost：9000 /＃/ deviceDetail / 我有一个控制器管理该视图。在进入该视图之前，我将一些变量设置为 $ rootScope （例如 $ rootScope.dashboards / em>）。

In my local route http://localhost:9000/#/deviceDetail/ I have a controller that manage that view. Before going to that view I set some variables to the $rootScope (for example $rootScope.dashboards).

在该视图上，我拥有对dashboards属性的访问权，但是当我用 F5 键刷新页面

Once on that view I have acces to dashboards property, but when I refresh the page with F5 key for example the property dashboards is lost.

我试图在localStorage变量中保存 $ rootScope ，但我得到了循环引用 JSON.stringify 方法的问题。

I tried to save the $rootScope on the localStorage variable but I got circular reference problems with the JSON.stringify method.

任何提示来管理？

推荐答案

AngularJS是一个JavaScript框架，一切都存储在内存堆中，当你打开一个页面时，堆被启动，在这种情况下，浏览器刷新就像关闭并重新打开页面。

AngularJS is a JavaScript framework, everything is stored in memory heap and the heap is starts when you open a page and it's destroyed after you close it. In this context, browser refresh is like closing and re-opening the page.

要在刷新后保留该值，应将其存储在cookie中，例如 $ cookie 或 sessionStorage / localStorage 。

To keep the value after refresh, you should store it in a cookie, for this you use for example $cookies or sessionStorage / localStorage as recommended by M K.
