如何确定一个字符串是否包含另一个字符串中的单词

function containsWords(targetString, searchString) {
  // 将字符串转换为小写，并使用空格分隔单词
  const targetWords = targetString.toLowerCase().split(' ');
  const searchWords = searchString.toLowerCase().split(' ');

  // 遍历目标字符串的单词数组，检查每个单词是否在待检查的字符串中出现
  for (let i = 0; i < searchWords.length; i++) {
    if (!targetWords.includes(searchWords[i])) {
      return false;
    }
  }

  return true;
}

// 示例用法
const targetString = "This is a sample string";
const searchString = "sample string";
const result = containsWords(targetString, searchString);
console.log(result);  // 输出 true
