如何使用Angularjs在本地存储中存储数据?

Currently I am using a service to perform an action, namely retrieve data from the server and then store the data on the server itself.

目前，我正在使用一个服务执行一个操作，即从服务器检索数据，然后将数据存储在服务器本身。

Instead of this, I want to put the data into local storage instead of storing it on the server. How do I do this?

相反，我希望将数据放入本地存储，而不是将其存储在服务器上。我该怎么做呢?

this is a bit of my code that stores and retrieves to local storage. i use broadcast events to save and restore the values in the model.

这是我的一段代码，用于存储和检索本地存储。我使用广播事件来保存和恢复模型中的值。

app.factory('userService', ['$rootScope', function ($rootScope) {

    var service = {

        model: {
            name: '',
            email: ''
        },

        SaveState: function () {
            sessionStorage.userService = angular.toJson(service.model);
        },

        RestoreState: function () {
            service.model = angular.fromJson(sessionStorage.userService);
        }
    }

    $rootScope.$on("savestate", service.SaveState);
    $rootScope.$on("restorestate", service.RestoreState);

    return service;
}]);

If you use $window.localStorage.setItem(key,value) to store,$window.localStorage.getItem(key) to retrieve and $window.localStorage.removeItem(key) to remove, then you can access the values in any page.

如果您使用$window.localStorage.setItem(key,value)来存储，$window.localStorage.getItem(key)来检索，$ window.localStorage.removeItem(key)来删除，那么您可以访问任何页面中的值。

You have to pass the $window service to the controller. Though in JavaScript, window object is available globally.

您必须将$window服务传递给控制器。虽然在JavaScript中，窗口对象是全局可用的。

By using $window.localStorage.xxXX() the user has control over the localStorage value. The size of the data depends upon the browser. If you only use $localStorage then value remains as long as you use window.location.href to navigate to other page and if you use <a href="location"></a> to navigate to other page then your $localStorage value is lost in the next page.

通过使用$window.localStorage.xxXX()，用户可以控制localStorage值。数据的大小取决于浏览器。如果只使用$localStorage，那么只要使用windows .location，值就会保持不变。href导航到其他页面，如果您使用导航到其他页面，那么您的$localStorage值将在下一页中丢失。

For local storage there is a module for that look at below url:

对于本地存储，有一个模块可以查看下面的url:

and other link for HTML5 local storage and angularJs

Use ngStorage For All Your AngularJS Local Storage Needs. Please note that this is NOT a native part of the Angular JS framework.

使用ngStorage满足您所有的AngularJS本地存储需求。请注意，这不是角JS框架的本机部分。

ngStorage contains two services: $localStorage and $sessionStorage.

ngStorage包含两个服务:$localStorage和$sessionStorage。

angular.module('app', [
   'ngStorage'
]).controller('Ctrl', function(
    $scope,
    $localStorage,
    $sessionStorage
){});

There is one more alternative module which has more activity than ngStorage

与ngStorage相比，还有一个可选模块具有更多的活动

angular-local-storage:

Depending on your needs, like if you want to allow the data to eventually expire or set limitations on how many records to store, you could also look at https://github.com/jmdobry/angular-cache which allows you to define if the cache sits in memory, localStorage, or sessionStorage.

根据您的需要，例如，如果您希望允许数据最终过期或设置存储记录数量的限制，您还可以查看https://github.com/jmdobry/angular-cache，它允许您定义缓存是否位于内存、localStorage或sessionStorage中。

I authored (yet another) angular html5 storage service. I wanted to keep the automatic updates made possible by ngStorage, but make digest cycles more predictable/intuitive (at least for me), add events to handle when state reloads are required, and also add sharing session storage between tabs. I modeled the API after $resource and called it angular-stored-object. It can be used as follows:

我编写了(另一个)有棱角的html5存储服务。我想让ngStorage实现自动更新，但让摘要周期更可预测/直观(至少对我来说)，在需要状态重载时添加事件来处理，并在选项卡之间添加共享会话存储。我根据$resource对API进行建模，并将其称为angular-stored对象。它的用途如下:

  angular
    .module('auth', ['yaacovCR.storedObject']);

  angular
    .module('auth')
    .factory('session', session);

  function session(ycr$StoredObject) {
    return new ycr$StoredObject('session');
  }

You can use localStorage for the purpose.

您可以为此目的使用localStorage。

Steps:

步骤:

add ngStorage.min.js in your file
add ngStorage dependency in your module
add $localStorage module in your controller
use $localStorage.key = value

One should use a third party script for this called called ngStorage here is a example how to use.It updates localstorage with change in scope/view.

我们应该使用一个名为ngStorage的第三方脚本，这里有一个如何使用的示例。它在范围/视图上更新localstorage。
