This is an old post, but for future reference in ASP.NET one can do the following to avoid blank action attributes:
这是一篇旧帖子，但是为了将来在ASP.NET中引用，可以执行以下操作以避免空白操作属性：
<form action="#" runat="server">
This will validate with W3C and does not require you to do any special coding to detect the page url you are currently on.
这将通过W3C验证，并且不要求您执行任何特殊编码来检测您当前所在的页面网址。

Omit the attribute action. According to HTML5 drafts, it is not required, but if present, its value must be non-empty. Reference: WHATWG HTML5 draft, description of action attribute.
省略属性动作。根据HTML5草案，它不是必需的，但如果存在，其值必须是非空的。参考：WHATWG HTML5草案，动作属性的描述。
