The name attribute is obsolete and shouldn't be used anyway. name属性已过时，无论如何都不应该使用。 It was used to define a place to link to .它用于定义链接到的位置。 The introduction of HTML 4 in 1998 replaced name on a elements with id on any element. 1998 年引入的 HTML 4 a元素上a name替换name任何元素上a id 。
That said, clicks happen in the browser.也就是说，点击发生在浏览器中。 Node.js, generally, is used for server-side programming. Node.js 通常用于服务器端编程。 You can't tell what user is clicking on in the browser unless you change browser-side code to pass that information to the server.除非您更改浏览器端代码以将该信息传递给服务器，否则您无法知道用户在浏览器中单击了什么。
Possibly what you should be doing is putting the data in the query string of the URL:可能您应该做的是将数据放入 URL 的查询字符串中：
href="/goodsPage?something=shoes"
And then you can read it from the URL on the server.然后你可以从服务器上的 URL 读取它。
If you were using Express.js then that would be a simple matter of reading the query property from the request object.如果您使用 Express.js，那么从请求对象中读取query属性就很简单了。
But with that pattern, it looks like putting the information in the path would be better:但是使用这种模式，看起来将信息放在路径中会更好：
href="/goodsPage/shoes"
Express.js would then let you read it from the route : Express.js 然后会让你从路由中读取它：
app.get('/goodsPage/:something', function (req, res) {
console.log(req.params.something);
res.send(...)
})
