暂停脚本，直到用户在 Node.JS 中按下回车键

Question

我有一个脚本，里面有一点信息。我希望它在用户按下回车键之前不做任何事情。我试过这个：

console.log("Welcome to the Roblox cursor backup script!\n This script will backup your current Roblox cursor and replace it with the old 2021 Roblox cursor.\n\n Please make sure you have a Roblox client closed. \n This script is prefixed at /Applications/Roblox.app, if you are non-admin please run the command with the --noadmin flag.\n\n Press enter to continue. \n\n ---------------------------------------------------------");
// if user presses enter in the terminal, continue
process.stdin.on('keypress', function (letter, key) {
    if (key.name === 'return') {
        console.log("User pressed enter/return, continuing...");
    } else{
        // pause the script until the user presses enter
        process.stdin.pause();
    }

});

但是，脚本立即继续。如何使脚本在用户按下 enter/return 之前不执行任何操作？

Answer 1

您可以简单地从标准输入中获取输入示例函数：

function waitForKey(keyCode) {
    return new Promise(resolve => {
        process.stdin.on('data',function (chunk) {
            if (chunk[0] === keyCode) {
                resolve();
                process.stdin.pause();
            }
        });
    });
}

现在，如果您想等待输入密钥：

await waitForKey(10);
