js获取请求数据

const urlParams = new URLSearchParams(window.location.search);
const specificParam = urlParams.get('paramName');

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

const xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onload = function () {
  if (xhr.status === 200) {
    const data = JSON.parse(xhr.responseText);
    console.log(data);
  }
};
xhr.send();

// 使用FormData
const form = document.querySelector('form');
form.addEventListener('submit', function (event) {
  event.preventDefault();
  const formData = new FormData(form);
  const data = {};
  formData.forEach((value, key) => {
    data[key] = value;
  });
  console.log(data);
});

// 直接访问表单元素
const input = document.querySelector('input[name="inputName"]');
const inputValue = input.value;

// 存储数据
localStorage.setItem('key', 'value');

// 获取数据
const value = localStorage.getItem('key');
