Storing JSON data in browser memory
提问by SharpCoder
I want to persist some JSON information in browser. Depending on user interaction with the application, I want to store 5-6 different JSON object into memory. What options I have to achieve this? Please suggest any library or plugin using which I can persist information in the browser.

Thanks

To add to the solutions given, I'd also want to add a reference link Storing Objects in HTML5 localStoragewhere this question is discussed nicely.
要添加到给出的解决方案中，我还想添加一个参考链接在 HTML5 localStorage中存储对象，其中很好地讨论了这个问题。
Below is the code
下面是代码
var testObject = { 'one': 1, 'two': 2, 'three': 3 };
// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));
// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');
console.log('retrievedObject: ', JSON.parse(retrievedObject));

You can use HTML5 storage which gives you both local and session storage.
您可以使用 HTML5 存储，它为您提供本地和会话存储。
Local storage persists it in a local cache and can therefore be accessed again in the future, despite the browser being closed.
本地存储将其保存在本地缓存中，因此即使浏览器已关闭，也可以在将来再次访问。
Session storage will only store the information for that particular session and will be wiped once the session ends.
会话存储将只存储该特定会话的信息，并在会话结束后被擦除。
e.g.
例如
//get item from storage
var foo = localStorage["bar"];
//set item in storage.
localStorage["bar"] = foo;

Use the HTML5 storage. This stores persistent data.
使用 HTML5 存储。这存储持久数据。
You can access it with localStorage["key"].
您可以使用localStorage["key"].
