Python mechanize - two buttons of type 'submit'
I tried using the nr parameter, without any luck.
I was able to get it to work with a combination of the name and label parameters, where "label" seems to correspond to the "value" in the HTML:
Here are my two submit buttons:
<input type="submit" name="Preview" value="Preview" /><input type="submit" name="Create" value="Create New Page" />... and here's the code that clicks the first one, goes back, and then clicks the second:
from mechanize import Browserself.br = Browser()self.br.open('http://foo.com/path/to/page.html')self.br.select_form(name='my_form')self.br['somefieldname'] = 'Foo'submit_response = self.br.submit(name='Preview', label='Preview')self.br.back()self.br.select_form(name='my_form')self.br['somefieldname'] = 'Bar'submit_response = self.br.submit(name='Create', label='Create New Page')There's a variant that also worked for me, where the "name" of the submit button is the same, such as:
<input type="submit" name="action" value="Preview" /><input type="submit" name="action" value="Save" /><input type="submit" name="action" value="Cancel" />and
self.br.select_form(name='my_form')submit_response = self.br.submit(name='action', label='Preview')self.br.back()submit_response = self.br.submit(name='action', label='Save')IMPORTANT NOTE - I was only able to get any of this multiple-submit-button code to work after cleaning up some HTML in the rest of the page.
Specifically, I could not have <br/> - instead I had to have <br /> ... and, making even less sense, I could not have anything between the two submit buttons.
It frustrated me to no end that the mechanize/ClientForm bug I hunted for over two hours boiled down to this:
<tr><td colspan="2"><br/><input type="submit" name="Preview" value="Preview" /> <input type="submit" name="Create" value="Create New Page" /></td></tr>(all on one line) did not work, but
<tr><td colspan="2"><br /><input type="submit" name="Preview" value="Preview" /><input type="submit" name="Create" value="Create New Page" /></td></tr>worked fine (on multiple lines, which also shouldn't have mattered).
I like mechanize because it was easy to install (just copy the files into my include directory) and because it's pretty simple to use, but unless I'm missing something major, I think that bugs like this are kind of awful - I can't think of a good reason at all why the first example there should fail and the second should work.
And, incidentally, I also found another mechanize bug where a <textarea> which is contained within a <p> is not recognized as a valid control, but once you take it out of the <p> container it's recognized just fine. And I checked, textarea is allowed to be included in other block-level elements like <p>.
I would suggest you to use Twill which uses mechanize (mostly monkeypatched). So say you have form with some fields and two submit buttons with names "submit_to_preview" and "real_submit". Following code should work.
BTW remember this is not threadsafe so you might want to use locks in case if you want to use the code in a threaded env.
import twill.commandsb = twill.get_browser()url = "http://site/myform"twill.commands.go(url)twill.commands.fv("2", "name", "Me")twill.commands.fv("2", "age", "32")twill.commands.fv("2", "comment", "useful article")twill.commands.browser.submit("real_submit")Hope that helps. Cheers.
