使用换行符时，Node.js提示同步会重复提示 [英] Node.js prompt-sync repeats prompt when using newline characters

问题描述

我正在处理JavaScript分配，要求我使用提示同步在Node.JS中.直到我尝试在提示中使用换行符\n为止，它都可以正常工作，这时键入的每个字符或退格键都会导致提示重复自身.

我如何做才能使用户输入显示在新行上(此练习的要求)而没有出现此问题?

问题代码:

if (guess < answer) {
  guess = prompt("Too low!\n> ");
} else if (guess > answer) {
  guess = prompt("Too high!\n> ");
}

输出屏幕截图

解决方案

您可以尝试使用此方法.

if (guess < answer) {
  console.log("Too low!");
  guess = prompt("> ");
} else if (guess > answer) {
  console.log("Too high!");
  guess = prompt("> ");
}

如果这不起作用，则可能是您自己代码的另一部分出现了问题.如果是这样，则prompt-sync模块可能有问题，如果您认为这是有效的解决方法.

I'm working on a JavaScript assignment that requires me to use prompt-synch in Node.JS. It works fine until I try to use a newline character \n within the prompt, at which point every character or backspace typed causes the prompt to repeat itself.

What could I do to get the user input to appear on a new line (a requirement of this exercise) without this issue?

Problem code:

if (guess < answer) {
  guess = prompt("Too low!\n> ");
} else if (guess > answer) {
  guess = prompt("Too high!\n> ");
}

解决方案

You can try this instead.

if (guess < answer) {
  console.log("Too low!");
  guess = prompt("> ");
} else if (guess > answer) {
  console.log("Too high!");
  guess = prompt("> ");
}

If this does not work then it is likely an issue with another part of your own code. If it does, then it is likely an issue with the prompt-sync module, which makes this a valid workaround if you believe it is.
