检查字符串是否包含没有regExp的字符串数组中的任何一个 [英] Check if string contains any of array of strings without regExp

问题描述

我正在检查字符串输入是否包含任何字符串数组.它通过了大多数测试，但未通过以下测试.

I am checking a string input whether it contains any of an array of strings or not. It is passing most of the tests but not the below one.

任何人都可以分解我的代码为何无法正常工作吗?

Can anyone break my code down why it is not working properly?

     function checkInput(input, words) {
      var arr = input.toLowerCase().split(" ");
      var i, j;
      var matches = 0;
      for(i = 0; i < arr.length; i++) {
        for(j = 0; j < words.length; j++) {
          if(arr[i] == words[j]) {
            matches++;
          }
        }
      }
      if(matches > 0) {
        return true;
      } else {
        return false;
      }
    };

checkInput("Visiting new places is fun.", ["aces"]); // returns false // code is passing from this test
checkInput('"Definitely," he said in a matter-of-fact tone.', 
    ["matter", "definitely"])); // returns false; should be returning true;

谢谢您的时间！

推荐答案

您可以为此使用功能性方法.尝试Array.some.

You can use functional methods for this. Try Array.some.

const words = ['matters', 'definitely'];
const input = '"Definitely," he said in a matter-of-fact tone.';
console.log(words.some(word => input.includes(word)));
