出现提示时，是否有一种方法可以在查询器中使用以前的答案(inquirer v6)? [英] Is there a way to use previous answers in inquirer when presenting a prompt (inquirer v6)?

问题描述

所以我想做的是在进一步询问问题时使用先前的答案.基本上，这样我就可以显示将要创建的内容的摘要并要求进行验证.

So what I want to do is use a previous answer when asking a question further down the line. Basically so that I can show a summary of what will be created and ask for a verification.

this.prompt([   
    {
      type: 'input',
      name: 'name',
      message: 'What is your name?'
      default: 'Jake'
    },
    {
      type: 'confirm',
      name: 'summary',
      message: 'Is this information correct? Your name is:' + answers.name',
    }

有没有简单的方法可以做到这一点?还是获得摘要类型的东西(列出所有以前的答案)的另一种方法?

is there an easy way to achieve this? Or another way to achieve a summary type thing that lists out all previous answers?

推荐答案

任一嵌套查询器调用:

inquirer
  .prompt({
    type: 'list',
    name: 'chocolate',
    message: "What's your favorite chocolate?",
    choices: ['Mars', 'Oh Henry', 'Hershey']
  })
  .then(() => {
    inquirer.prompt({
      type: 'list',
      name: 'beverage',
      message: 'And your favorite beverage?',
      choices: ['Pepsi', 'Coke', '7up', 'Mountain Dew', 'Red Bull']
    });
  });

或使用when功能.

{
  type: 'confirm',
  name: 'summary',
  message: 'Is this information correct? Your name is:' + answers.name,
  when: function( answers ) {
    // Only run if user set a name
    return !!answers.name;
  },
}
