如何获取存储在localStorage中的对象的值? [英] How do I get an object's value stored in localStorage?

问题描述

我已将具有多个属性的对象存储在localStorage中.它不包含单个值，例如字符串或数字. localStorage密钥的名称为UserData，其值为以下对象:

I have stored an object with multiple properties in localStorage. It does not contain a single value like a string or a number. The name of the localStorage key is UserData and its value is the following object:

{
    key: "1287C31D714BE16FBD44D093E4173CFF"
    logTime: "20191013190439"
    operatorDni: "46653980"    
}

我需要检索对象属性operatorDni的值，以便在我的代码中执行一些操作.我尝试使用以下代码来检索它:

I need to retrieve the value of the object property operatorDni in order to perform some actions in my code. I have tried to retrieve it using this line of code:

operatorDni: string;

this.operatorDni= localStorage.getItem('UserData.operatorDni');

但是我得到了null.

如何使用键在localStorage中获取对象的属性?我在做什么错了?

How can I get a property of an object in localStorage with the key? What am I doing wrong?

非常感谢您.

推荐答案

使用JSON.parse之类的

var userData= JSON.parse(localStorage.getItem('UserData'))
this.operatorDni=userData.operatorDni;

也喜欢保存

localStorage.setItem('UserData',JSON.stringify(yourObject))
