英文:
Get specific value from Localstorage key and populate div
问题
我有一个存储在localStorage中的键，我想获取特定的值并将其填充到一个元素中。
示例：
<div id="results"></div>
document.getElementById('results').innerHTML = localStorage.getItem('customer');
customer = {
"fullname": "John Doe",
"firstname": "John"
};
当然，这会输出整个键。我如何检索并显示只有fullname的值？
英文:
I have a key in localStorage and I want to get specific value and populate an element with it.
Example:
<div id="results"></div>
document.getElementById('results').innerHTML = localStorage.getItem('customer');
customer = {
"fullname": "John Doe",
"firstname": "John"
};
This of course outputs the full key. How do I retrieve and display just the value of fullname ?

你可以使用JSON.parse()来解析字符串值并获取你需要的键：
var customer = JSON.parse(localStorage.getItem('customer'));
var fullname = customer.fullname;
document.getElementById('results').innerHTML = fullname;
英文:
You can use JSON.parse() to parse the string value and get the key you need:
var customer = JSON.parse(localStorage.getItem('customer'));
var fullname = customer.fullname;
document.getElementById('results').innerHTML = fullname;
