Using Perl/CGI/Javascript to enable an HTML button to retrieve contents from a file and have them displayed.?

Question

Basically, I think the problem is that I don't want to the contents of a form submitted when the button is clicked. Once the button is clicked, some input fields will be populated with infromation retrieved from a file on the web server..

I'm a little new to this CGI thing so be kind. ;-)

Thanks,
Mark

Answer 1

that's not cgi.... it comes into the ajax family. ajax & json. both asynchronously connect to the server (much like cgi) get some data. You get the data in the form of a string or fully parsed into a dom!



Now if that sounds cool but a lot of work, you are right (about the cool part).



ajax low level native javascript can be a pain in the ***! But when you use a code library that already does the dirty work, it's just a few lines of javascript! (really, just a few lines)!



I use jquery (http://jquery.com) and it has made a big difference in many of my sites!
