SessionStorage 和 json 对象

Question

user: {firstName: "loki", lastName: "ch"}

I am storing this user in session storage.

$window.sessionStorage.user = user;

when i retrieved it back using $window.sessionStorage.user , i got:

[object Object] 

I want in JSON. Any suggestions?

Answer 1

Convert it to JSON before saving it.

$window.sessionStorage.user = JSON.stringify(user);

Then when you're loading it, parse the JSON.

var user = JSON.parse($window.sessionStorage.user);

Answer 2

Set the item

sessionStorage.setItem('user', user)

Get the item

var item = sessionStorage.getItem('user')
var user = item ? JSON.stringify(item) : {}

Answer 3

Apparently for Typescript users in React for example, You'll have to pass it as a string

JSON.parse(`${sessionStorage.getItem("session storage item name")}`)
