如果没有“SubmitControl”，如何使用Mechanize提交表单

Question

我有this页面，我正在尝试填写表单，然后提交评论，但是当我使用时

for i in br.forms():
    print i

我得到了

<storytextid=35686233 application/x-www-form-urlencoded
<TextControl(name=)
<HiddenControl(name_default=Name:) (readonly)>
<TextareaControl(review=Please ignore this message)>
<HiddenControl(review_default=Type your review here.) (readonly)>
<IgnoreControl(action=<None>)>
<HiddenControl(storyid=9652709) (readonly)>
<HiddenControl(chapter=1) (readonly)>
<HiddenControl(storytextid=35686233) (readonly)>>

注意this stackoverflow question

中缺少SubmitControl

<HiddenControl(<None>=2582580) (readonly)>
<TextareaControl(post-text=)>
<HiddenControl(fkey=47c5f6845374787ee763de7fbcf2ec24) (readonly)>
<TextControl(author=)>
<HiddenControl(manual-openid=) (readonly)>
<HiddenControl(use-facebook=false) (readonly)>
<IgnoreControl(<None>=<None>)>
<TextControl(display-name=)>
<TextControl(m-address=)>
<TextControl(display-name=)>
<TextControl(m-address=)>
<SubmitControl(<None>=Post Your Answer) (readonly)>
<HiddenControl(legalLinksShown=1) (readonly)>>

所以我跑的时候

br.submit()

没有任何反应，没有错误，似乎没有错，但审查没有显示出来。 当我跑步时

br.title()

返回None

如何提交没有SubmitControl的表单？
