What can trigger a form submit on disabled JavaScript without button-/input (of type submit)-tags

Question

I have a form which should never be submitted on disabled JavaScript.

<form id="xxx" name="xxx" action="xxx">
  <input type="hidden" name="age">
  <input type="text" name="firstname">
  <input type="text" name="lastname">
</form>

It has no button-tags or an input-tag with type "submit" ( <input type="submit" ). Could any other action (besides enabled JavaScript and client-side manipulation) submit this form?

浏览器可以使用快捷键激活提交事件，但这取决于浏览器，我看不到任何其他可能性。
