what is the easiest web scraping tool that handles javascripts
<p>I would like to make a web scraping application that is able to log in to a website (I was able to do this with twill (python)), and also to be able to execute JavaScript which trigger access to other pages.</p>

<p>I would definitely prefer to use something in python, but I am ready to try something new. I have installed mechanize, watir, Hojocki, etc. but not sure if this really helps.</p>
