Javascript and Web-site navigation using LWP, et. al

mckfuller has asked for the wisdom of the Perl Monks concerning the following question:

Aloha,

I am trying to write an application to navigate through a web site that uses a lot of javascript. A lot of it is to determine what uri fragment to append to the current uri for navigation. There is other, more meaty, javascript that I'm not sure I can duplicate easily in my code. Is there a way to "run" the javascript as I am traversing the site?

No pressure or anything, but if I don't figure this out soon, I'm up a creek.

Aloha,
mckfuller

I haven't used it myself, but JavaScript::SpiderMonkey and the javascript.pm modules both say they can eval js code by providing interfaces to two different javascript engines. I could have sworn I saw someone talking about a subclass of WWW::Mech that spoke javascript, but I guess I was wrong. -- jpg	[reply]

i didn't install them on my box, because i won't need them - hence i can't tell you whether these packages will fulfill your needs. however, take a loot at CPAN: http://www.cpan.org/authors/id/J/JP/JPIERCE/Data-JavaScript-1.08.tgz http://www.cpan.org/authors/id/J/JP/JPIERCE/Data-JavaScript-LiteObject-1.04.tgz language is a virus from outer space.

I would actually recommend to not look at the above mentioned packages.. because I did, and they create javascript structures, not parse them. I'm sorry I can't offer any more help. You may have a legitimate requirement to parse javascript on webpages, but as far as I know this is near impossible.. I'm most curious to see if you get a better answer in this forum!	[reply]

You may want to try Form Builder which generates js on the fly.	[reply]

You and thcsoft both have the wrong idea.	[reply]
