How to click a link that has [removed]__doPostBack in href?

Question

I am writing a screen scraper script in python with module \'mechanize\' and I would like to use the mechanize.click_link() method on a link that has javascript:__doPostBack

Answer 1

>>> next_link.__class__.__name__
'Link'
>>> next_link
Link(base_url='http://www.citius.mj.pt/Portal/consultas/ConsultasDistribuicao.aspx', url="javascript:__doPostBack('ctl00$ContentPlaceHolder1$Pager1$lnkNext','')", text='2', tag='a', attrs=[('id', 'ctl00_ContentPlaceHolder1_Pager1_lnkNext'), ('title', 'P\xc3\xa1gina seguinte: 2'), ('href', "javascript:__doPostBack('ctl00$ContentPlaceHolder1$Pager1$lnkNext','')")])
>>> req = mech.click_link(next_link)
>>> req

>>> req.has_data()
False
