javascript - 在 InquirerJS 中重复一组问题

Question

有没有办法重新设置问题或让某个答案将问题引向另一个先前的问题？

var questions = [{
{
  name: 'morefood',
  message: 'Do you want more food?',
  type: 'list',
  choices: [ 'Yes', 'No'],
},{
  name: 'choiceoffood',
  message: 'Which food do you want more of?',
  type: 'list',
  choices: [ 'Hamburgers', 'Fries', 'Hotdogs']
  when: function(answers) {
    return answers.morefood === 'Yes';
  }
}, {
  name: 'quantityoffood',
  message: 'How much more do you want?',
  type: 'input',
  when: function(answers) {
    return answers.quantityoffood === 'Yes';
  }
},{
  name: 'confirmfood',
  message: 'Do you still want more food?',
  type: 'list',
  choices: [ 'Yes', 'No'],   <=========== if yes then goes back to choiceoffood
}, 
]

Answer 1

这似乎有点老套，但我相信您必须在您的应用程序逻辑中处理它。例如:

const questionA = {
    type: 'input',
    message: 'Do you like fruit?',
    name: 'questionA',
}

const questionB = {
    type: 'input',
    message: 'What is your favorite fruit?',
    name: 'questionB',
}

const questionC = {
    type: 'input',
    message: 'what is your favorite candy?',
    name: 'questionC',
}

inquirer
    .prompt(questionA)
    .then(answers => {
        if (answers.questionA === 'yes') {
           return inquirer.prompt(questionB)
        } else {
           return inquirer.prompt(questionC)
        }
    })
    .then(answers => {
        if (answers.questionB) {
             return console.log(answers.questionB, 'is a great fruit');
        } 
        if (answers.questionC) {
            return console.log(answers.questionC, 'is a great candy');
        }
    })

更新:

仔细查看文档后，似乎“何时”才是正确的解决方案。

when: (Function, Boolean) Receive the current user answers hash and should return true or false depending on whether or not this question should be asked. The value can also be a simple boolean.
