HTML表单的`name`属性有什么意义？ [英] What's the point of HTML forms `name` attribute?

问题描述

HTML表单上的名称属性的要点是什么？据我所知，你不能在提交时阅读表单名称或做任何事情。它有什么作用？

What's the point of the name attribute on an HTML form? As far as I can tell, you can't read the form name on submission or do anything else with it. Does it serve a purpose?

推荐答案

简而言之，可能过于简单化了一点：它被用来代替 id 用于不理解 document.getElementById 。

In short, and probably oversimplifying a bit: It is used instead of id for browsers that don't understand document.getElementById.

的浏览器这些天它没有真正的目的。在使用 name 来描述如何在提交表单时如何发送控制值以及 id之前，这是浏览器大战早期的遗留问题识别页面内的元素已经结算。

These days it serves no real purpose. It is a legacy from the early days of the browser wars before the use of name to describe how to send control values when a form is submitted and id to identify an element within the page was settled.
