如何获取两个特定单词之前和之后的所有字符串？

function getWordsBeforeAndAfter(text, word1, word2) {
  // 将文本分割成单词数组
  const words = text.split(' ');

  // 找到目标单词在数组中的索引位置
  const index1 = words.indexOf(word1);
  const index2 = words.indexOf(word2);

  // 获取目标单词之前和之后的所有单词
  const wordsBefore = words.slice(0, index1);
  const wordsBetween = words.slice(index1 + 1, index2);
  const wordsAfter = words.slice(index2 + 1);

  // 将获取到的单词数组拼接成字符串
  const result = wordsBefore.join(' ') + ' ' + wordsBetween.join(' ') + ' ' + wordsAfter.join(' ');

  return result;
}

// 示例用法
const text = 'This is an example sentence to demonstrate the function.';
const word1 = 'example';
const word2 = 'function';

const result = getWordsBeforeAndAfter(text, word1, word2);
console.log(result);
