如何检查输入的单词是否等于数组中的任何字符串

Question

我正在尝试制作输入字段（onChange带有道具的方法）。当我输入特定问题 ( string) 时，我会得到答案。我设法为单个字符串做到这一点，但我想多次传递一个字符串数组而不是一个字符串。const newContent = (props) => {let questions = '';   if (props.question === "let") {questions = <p> answer here </p>   } else if (props.question === "var") {questions = <p> answer here </p>   } else if (props.question === "const") {questions = <p> answer here </p>   }let nextQuestion = ["let", "var", "const"];   if (props.question === nextQuestion) {nextQuestion = <p> answer here </p>   }}

Answer 1

这是你想要的？

const anwers = 

    { let:   '<p> answer here for let </p>'

    , var:   '<p> answer here for var </p>'

    , const: '<p> answer here for const </p>'

    }

const newContent = props => anwers[props] ?  anwers[props] : 'bad value';

console.log( newContent('var'))

Answer 2

像 ["let", "var", "const"].includes(props.question)
