如何在网页中搜索字符串并打印出存在搜索字符串的整行？

function searchAndPrintLines(searchString) {
  const allLines = document.getElementsByTagName('*');
  for (let i = 0; i < allLines.length; i++) {
    if (allLines[i].innerHTML.includes(searchString)) {
      console.log(allLines[i]);
    }
  }
}

searchAndPrintLines('搜索字符串');
