In proper HTML, must an <input> be in a <form>?

Question

I need a few input elements, but their values won't be submitted anywhere - they're just going to be manipulated by some client-side JavaScript. Do I have to place them in a <form> to have legit HTML, or can they just be free-standing?

Answer 1

不。如果您要提交服务器，则只需要一个表单。
