Access to javascript of web pages
Hi.
I'm a newbie with screen-scraper. I've worked with some tutorials and searched the forums and have not found a definitive answer:
Is it possible to have access to javascript variables inside a web page?
I tried to scrape values of a web page that are generated with javascript via document.getElementById("id").... and I have not found a solution.
Thanks.

We don't run any JavaScript, but you should be able to see either the values you can scrape and use, or see the calculations you need, and you can emulate them in a screen-scraper script.
How to read the javascript variable?
I know the name of the variable. The value of the variable is generated on the web server, not in the javascript code of the web page. The value of the variable is written with javascript via getElementById('xxx') to a html tag.
My problem is: How can I read (scrape) the value of this variable?

If it's generated on the backend, it has to be in the HTTP response somewhere. I've once seen a site that needed a session ID in the URL, and the URL was the only place it showed up, so I caught the first redirect, used scrapeableFile.getCurrentURL() and parsed it out. Aside from that it must be in the response somewhere.
