js复制内容到另一个页面显示

// 存储数据
localStorage.setItem('myData', JSON.stringify({ name: 'John', age: 30 }));

// 在另一个页面读取数据
window.onload = function() {
    const data = JSON.parse(localStorage.getItem('myData'));
    if (data) {
        document.getElementById('displayArea').innerText = `Name: ${data.name}, Age: ${data.age}`;
    }
};

// 在源页面编码数据并跳转
const data = encodeURIComponent(JSON.stringify({ name: 'John', age: 30 }));
window.location.href = `targetPage.html?data=${data}`;

// 在目标页面解码并显示数据
window.onload = function() {
    const urlParams = new URLSearchParams(window.location.search);
    const data = JSON.parse(decodeURIComponent(urlParams.get('data')));
    document.getElementById('displayArea').innerText = `Name: ${data.name}, Age: ${data.age}`;
};

// 客户端代码
const socket = new WebSocket('ws://example.com/socketserver');

socket.onopen = function() {
    socket.send(JSON.stringify({ name: 'John', age: 30 }));
};

socket.onmessage = function(event) {
    const data = JSON.parse(event.data);
    document.getElementById('displayArea').innerText = `Name: ${data.name}, Age: ${data.age}`;
};

// 服务器端代码（Node.js示例）
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', function connection(ws) {
    ws.on('message', function incoming(message) {
        console.log('received: %s', message);
        ws.send(message); // 将接收到的消息回传给客户端
    });
});
