如何从 sessionStorage 中获取其中一个值

Question

This is how my sessionStorage looks:

let user = sessionStorage.getItem("user") -> {"status":"login","id":204}

In a different part of the code I want to get the value of Id

I tried doing it like this let id = user.id; , however it returns the value null

The Session Storage doesn't allow to store objects. You can use JSON.stringify() and JSON.parse() to store JSON.

 sessionStorage.setItem("user", JSON.stringify({ id: 123 })); let user = JSON.parse(sessionStorage.getItem("user")); let id = user.id; console.log(id);

Note: Doesn't work in snippet
