JavaScript中的计分函数，只有一个初始提示
我似乎不知道如何只提示用户选择一个评分算法一次，而不是每次。我知道我希望能够为用户提供JavaScript中的计分函数，只有一个初始提示,javascript,algorithm,function,Javascript,Algorithm,Function,我似乎不知道如何只提示用户选择一个评分算法一次，而不是每次。我知道我希望能够为用户提供initialPrompt选择评分方法，然后提示他们输入要评分的单词。我正在努力解决的问题是将initialPrompt与runProgram函数分开，这样它就不会在每次完成单词评分时一直调用它 以下是我尝试过的： 1.我试图在runProgram函数之外调用initialPrompt，但似乎无法获取intialprompt的返回值，以便在runProgram中使用它。我已尝试将初始提示设置为runProgr
initialPromptinitialPromptrunProgram1.我试图在
runPrograminitialPromptintialpromptrunProgram初始提示设置为runProgram
中的变量
2.我尝试创建一个新函数，只在runProgram
返回一个分数后对一个新词进行评分，这样我就不必调用runProgram
，后者反过来调用initialPrompt
let word = '';
//code for the initial user prompt which asks them to choose a scoring algorithm.
function initialPrompt() {
const input = require('readline-sync');
let info = input.question(`Welcome to the Scrabble score calculator!
Which scoring algorithm would you like to use?
0 - Scrabble: The traditional scoring algorithm.
1 - Simple Score: Each letter is worth 1 point.
2 - Bonus Vowels: Vowels are worth 3 pts, and consonants are 1 pt.
Enter 0, 1, or 2:`)
return info
}
// Code for runProgram function here:
function runProgram(scoringAlgorithms) {
//initialPrompt();
let num = initialPrompt();
num = (Number(num));
const readline = require('readline-sync');
let word = readline.question(
`Enter a word to score(Typing 'Stop' will end the program): `);
word = word.toLowerCase();
//console.log(word);
//console.log(typeof num);
//console.log(num===0);
//conditionals
if (num === 0) {
//console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[0].name);
console.log(word);
console.log(`Is worth ${scrabbleScoring(word, newPointStructure)} points`);
runProgram()
} else if (num === 1) {
console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[1].name);
console.log(word);
console.log(`Is worth ${simpleScore(word)} points`);
runProgram()
} else if (num === 2) {
console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[2].name);
console.log(word);
console.log(`Is worth ${bonusVowels(word)} points`);
runProgram()
} else if (num === 'Stop')
console.log("Goodbye")
}
下面是运行时的结果

以下是完整的示例代码：
尝试将评分算法设置为变量，并在runProgram（）中检查变量是否已设置。如果设置为，则不调用初始提示
let word = '';
let scoringAlgo = ''
//code for the initial user prompt which asks them to choose a scoring algorithm.
function initialPrompt() {
const input = require('readline-sync');
let info = input.question(`Welcome to the Scrabble score calculator!

return info
}
// Code for runProgram function here:
function runProgram(scoringAlgorithms) {
//initialPrompt();
if (scoringAlgo == ''){
let num = initialPrompt();
num = (Number(num));
}
else {
let num = scoringAlgo;
}
const readline = require('readline-sync');
let word = readline.question(
`Enter a word to score(Typing 'Stop' will end the program): `);
word = word.toLowerCase();
//console.log(word);
//console.log(typeof num);
//console.log(num===0);
//conditionals
if (num === 0) {
//console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[0].name);
console.log(word);
console.log(`Is worth ${scrabbleScoring(word, newPointStructure)} points`);
runProgram()
} else if (num === 1) {
console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[1].name);
console.log(word);
console.log(`Is worth ${simpleScore(word)} points`);
runProgram()
} else if (num === 2) {
console.log(initialPrompt);
console.log("Scoring Choice: ", scoringAlgorithms[2].name);
console.log(word);
console.log(`Is worth ${bonusVowels(word)} points`);
runProgram()
} else if (num === 'Stop')
console.log("Goodbye")
}
不要使用递归在循环中运行代码，使用while
循环。您可以使用break
中断循环
另外，您可以将word
与stop
进行比较，而不是num
函数运行程序（scoringAlgorithms）{
//initialPrompt（）；
设num=initialPrompt（）；
num=（Number（num））；
const readline=require（'readline-sync'）；
while（true）{
让word=readline.question(
`输入要评分的单词（键入“停止”将结束程序）：`）；
word=word.toLowerCase（）；
如果（字==“停止”）{
console.log（“再见”）；
打破
}
如果（num==0）{
//console.log（initialPrompt）；
log（“评分选择：”，评分算法[0].name）；
console.log（word）；
log（`Is worth${scrabblescording（word，newPointStructure）}points`）；
}else if（num==1）{
console.log（initialPrompt）；
log（“评分选择：”，评分算法[1].name）；
console.log（word）；
log（`Is worth${simpleScore（word）}points`）；
}else if（num==2）{
console.log（initialPrompt）；
log（“评分选择：”，评分算法[2]。名称）；
console.log（word）；
log（`Is-worth${bonusvorels（word）}points`）；
}
}
}
欢迎来到堆栈溢出；您的runProgram
函数似乎只调用initialPrompt
函数一次，而不是在循环中，因此您的runProgram
函数必须被多次调用。如果没有看到一段完整的代码来计算它在做什么，我们将无法回答这个问题；请在这里发布一个。谢谢@kaya3：您需要编辑您的问题以包含代码。谢谢@irtazaakram您将在完整的代码链接中看到，我将scoringAlgorithms
设置为三个数字的数组，这就是我在条件部分中比较的num
。那部分的工作方式和我期望的一样。我想帮助您找到一种方法，在调用runProgram
函数时，不要连续调用initialPrompt
。
