javascript - 在 JavaScript 中查找句子中的单词？

Question

我已经设置了列表

示例:

const answerList = [{index: 2, answer: nice}, {index: 5, answer: sunday} ...] 

就这样

我有一句话

示例:

“嗨，我是西奥，很高兴见到你。你好吗”

所以我想检查句子中是否有正确答案，如果找到，则返回answerList set

示例:

return value is [{index: 2, answer: nice}]

因为句子里有一个“nice”这个词。

谁能告诉我一个好方法吗？

Answer 1

您可以尝试使用Array.prototype.filter()和 String.prototype.includes() :

const answerList = [{index: 2, answer: 'nice'}, {index: 5, answer: 'sunday'}];
const sentence = "hi i'm theo nice to meet you. how are you";
var res = answerList.filter(a => sentence.includes(a.answer));
console.log(res);
