html怎么读取本地文本文件

<code class="html"><input type="file" id="file-input"><script>
  const fileInput = document.getElementById(\'file-input\');
  fileInput.addEventListener(\'change\', (e) => {
    const file = e.target.files[0];
    const reader = new FileReader();
    reader.onload = (e) => {
      const text = e.target.result;
      // 使用 text
    };
    reader.readAsText(file);
  });
</script>
