表单元素上的action属性可以为空吗? [英] Can the action attribute on a form element be empty?

问题描述

从HTML5开始，广泛使用并推荐的action=""是无效的HTML.

As of HTML5, the widely used and recommended action="" is invalid HTML.

根据规格:

如果指定了action和formaction内容属性，则必须具有 一个有效的URL值.

The action and formaction content attributes, if specified, must have a value that is a valid URL.

那么将action属性指向当前页面的正确方法是什么?

So what is the correct way to have the action attribute point to the current page?

我当前正在使用

action="<php htmlspecialchars($_SERVER["REQUEST_URI"]); ?>"

推荐答案

的确，action=属性不能为空，因为空字符串不是有效的URL.但是，简单地将其保留，然后让浏览器将其找出来是有效的.

It's true that the action= attribute may not be empty, as an empty string is not a valid URL. However, it is valid to simply leave it out, and let the browser figure it out.

浏览器将假定当前页面.

The browser will assume the current page.
