javascript - 在nodejs中迭代地从控制台获取用户输入？

Question

如何在循环中从控制台获取输入？

假设 Node 提示询问一个类(class)有多少学生？该用户输入5后，应该有一个提示询问5次“一一输入他们的名字”，所有名称都必须存储在数组中

试试这个

const readline = require('readline');
const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

let n;
let array = []

function mainfunction() {
    if( n == array.length){
        console.log("your output: ",  array)
        rl.close()
    }
    else{
        rl.question('enter student name one by one \n', (name) => {
            array.push(name)
            mainfunction()
        })
    }
 }

rl.question('enter the number of students ', (answer) => {
    n = answer
    mainfunction()
});
