Comment choisissez-vous les choix qui ne sont pas dans un formulaire en utilisant Python?

Question

Je voudrais savoir comment puis-je sélectionner un menu d'option qui n'est pas dans un formulaire en utilisant Mechanize? La page que je reçois ces données, a l'option de sélection dans un div et non sur un formulaire

<select name="name" onchange="someJavaScript;"> 
    <option value="-1">Value -1</option> 
    <option value="1">Value 1</option> 
    <option value="2">Value 2</option> 
</select>

Pourriez-vous nous fournir un lien vers le site Web?

Mise à jour: Vous ne savez pas si vous avez résolu le problème. Je viens de recevoir les travaux suivants pour moi, et je crois que cela devrait fonctionner pour vous aussi:

    def bar(*args, **kw): 
     kw['ssl_version'] = ssl.PROTOCOL_TLSv1 
     return func(*args, **kw) 
    return bar 

ssl.wrap_socket = sslwrap(ssl.wrap_socket)

# ----------------------------------------------- 
# In case the control has name 'p', use the following to set the value:

response = mechanize.urlopen(form.click())

# I don't have the page source. Hope it helps. 
html = """<select name="name" onchange="someJavaScript;"> 
    <option value="-1">Value -1</option> 
    <option value="1">Value 1</option> 
    <option value="2">Value 2</option> 
</select>""" 

# work on the string above 
forms = mechanize.ParseString(html, 'fake') 

# there is only one form here, form is HTMLForm instance 
form = forms[0] 

control = form.controls[0] # the select 

# All values for control 'name' 
print [item.attrs['value'] for item in control.items] # ['-1','1','2'] 

# The current value for this control 
print form['name'] # ['-1'] 

# Select a choice (e.g. choice with value '2') 
form['name'] = ['2'] 

# Verify the value 
print form['name'] # ['2']
