Use JavaScript to fetch source of a page 1

[quarryknight]

Before you yell at me for posting with malicious intent, hear me out:

I am currently working on a price comparison website for the textbooks that my college sells (since they overprice everything). My goal is to fetch the source of a page on Half.com to get the currently lowest price of a textbook by ISBN.

I was wondering it is possible to do such a thing with JavaScript, and if possible, how would I go about getting started. Since JavaScript is client-side, I may not be able to do it at all. If it is impossible to do so with JavaScript, would I be able to do it with PHP or ASP?

Thank you very much for your time.

I *guess* you could open the page in an iframe or in a new window and call [tt]newpage.document.body.innerHTML[/tt], but it is much easier in PHP, as in use one built-in function: file_get_contents(), I believe.

Glorious, simply glorious. It parses the price very nicely.

I really didn't want to have to use JavaScript, since my page runs primarily on PHP anyway. Thanks for the help.
