PostMessage后台发送ctrl +键

otherWindow.postMessage(message, targetOrigin, [transfer]);

function simulateKeyPress(keyCode) {
    var event = new KeyboardEvent('keydown', {
        'keyCode': keyCode,
        'ctrlKey': true,
        'bubbles': true,
        'cancelable': true
    });
    document.dispatchEvent(event);
}

// 模拟 Ctrl + 键（假设这里的键码是 191 代表 /）
simulateKeyPress(191);

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);
    });

    // 发送消息到客户端
    ws.send('simulateCtrlPlus');
});

const socket = new WebSocket('ws://localhost:8080');

socket.onmessage = function(event) {
    if (event.data === 'simulateCtrlPlus') {
        simulateKeyPress(191); // 使用上面的函数
    }
};
