javascript - 当其键与特定字符串匹配时循环遍历 Javascript 对象值

Question

我有一个函数可以循环遍历对象的键，直到该键与输入中的关键字匹配。找到匹配项后，如何循环匹配的对象键值？

let obj = {
  music: {
    "do you like music": "Yes I do",
    "what music do you like": "Jazz"
  },

  sports: {
    "Do you like sports": "Yes"
  }
};

let input = "i like music";

function run(input) {
  let newStr = input.split(' ');
  let key = Object.keys(obj);
  key.forEach((key) => {
    newStr.forEach((str) => {
      if (key === str) {
        console.log(key)
      }
    });
  });
};

run(input);

您可以使用Array.flatMap并从obj返回匹配的单词value

我假设您想要返回整个值来匹配键

let obj = {
  	music:{
    	"do you like music":"Yes I do",
      "what music do you like": "Jazz"
    },
    
    sports:{
    	"Do you like sports": "Yes"
    }
};

function run(i) {
  return i.split(' ').flatMap(d => obj[d] || [])[0]
}

console.log(run("i like music"))

console.log(run("i like sports"))
