@耳朵的主人²º²⁵ 哈哈，帮你写了下，保存用户信息的，找个地方加上就行

// 页面加载时自动从 localStorage 填入值
window.addEventListener(‘DOMContentLoaded’, () => {
const author = localStorage.getItem(‘author’);
const email = localStorage.getItem(’email’);
const url = localStorage.getItem(‘url’);

if (author) document.getElementById(‘author’).value = author;
if (email) document.getElementById(’email’).value = email;
if (url) document.getElementById(‘url’).value = url;
});

// 提交按钮点击事件
document.getElementById(‘submit’).addEventListener(‘click’, () => {
const author = document.getElementById(‘author’).value.trim();
const email = document.getElementById(’email’).value.trim();
const url = document.getElementById(‘url’).value.trim();

if (author && email) {
localStorage.setItem(‘author’, author);
localStorage.setItem(’email’, email);
localStorage.setItem(‘url’, url); // url 可以为空也保存
console.log(‘信息已保存到 localStorage’);
} else {
console.log(‘author 和 email 不能为空’);
}
});

换行的那个，还是要具体分析才行
