我只是尝试新事物。这是https://lodash.com/docs/4.17.15 lodash docs网站，左侧是具有所有功能的菜单。我想知道是否有任何方法可以在控制台中提取这些TD元素的所有名称？
我发现有324个元素
document.querySelectorAll('react-menu-container ul > li')
现在我需要提取每个名称。
使用Array#from将您document.querySelectorAll('react-menu-container ul > li')转换为数组，然后Array#map遍历结果并获取每个项目的文本内容。
您也忘记了.前面的react-menu-container。
const res = Array.from(document.querySelectorAll('.react-menu-container ul > li')).map(item=>item.textContent);
console.log(res);<div class="react-menu-container"><ul class=""><li class=""><a href="https://lodash.com/docs/4.17.15#countBy"><code><span class="subtle-punctuation">_.</span><!-- react-text: 344
