我是DOM查询的新手，我想知道是否可以通过Xpath以与下面提到的代码类似的方式直接查询DOM元素?

I'm new to DOM querying and I'm wondering if it is possible to query DOM elements directly by Xpath in a similar way to the below-mentioned code?

document.getElementById("searchInput");

谢谢！

推荐答案

仅使用XPath的等效语句就是

The equivalent statement using only XPath would be

xPathResult = document.evaluate('//*[@id="searchInput"]', document); if(xPathResult){ element = xPathResult.iterateNext(); }

在MDN上的浏览器中，查看 XPath简介一些示例和用法.
