js 打开页面 传递参数

// 打开新页面并传递参数
const params = new URLSearchParams({ key1: 'value1', key2: 'value2' });
window.open(`https://example.com/page?${params.toString()}`);

const urlParams = new URLSearchParams(window.location.search);
const key1 = urlParams.get('key1');
const key2 = urlParams.get('key2');
console.log(key1, key2);

// 在当前页面存储数据
localStorage.setItem('key1', 'value1');
localStorage.setItem('key2', 'value2');

// 打开新页面
window.open('https://example.com/page');

const key1 = localStorage.getItem('key1');
const key2 = localStorage.getItem('key2');
console.log(key1, key2);

// 清除数据（可选）
localStorage.removeItem('key1');
localStorage.removeItem('key2');

<!-- 表单提交 -->
<form id="myForm" action="https://example.com/page" method="POST">
  <input type="hidden" name="key1" value="value1">
  <input type="hidden" name="key2" value="value2">
</form>
<script>
  document.getElementById('myForm').submit();
</script>

// 假设使用 Node.js 服务器读取 POST 数据
const express = require('express');
const app = express();

app.use(express.urlencoded({ extended: true }));

app.post('/page', (req, res) => {
  const key1 = req.body.key1;
  const key2 = req.body.key2;
  console.log(key1, key2);
  res.sendFile(__dirname + '/page.html');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
