I'm looking to add a calculation area to one of our sites, so that people can generate answers to simple equations by filling in a form. Ideally I'd like to do this in JS, rather than submitting data to the server. I know that I can do this manually by creating lots of fields and then coding the calculation in JS (there are many tutorials out there), but what I was hoping for was some sort of jQuery plugin (or similar) that will help me generate the form much more easily, as I have a huge number of pages to create. Has anyone done this before within XF? I would be very interested to hear how you would go about adding a repository of calculators to your site, as I'm not sure on the best way to code this. An example of the sort of calculator I'd like is as follows: Units: Radio buttons for Meters or Feet Mass: Numeric Only Field Acceleration: Numeric Only Field Force: Calculated based on MxA, correct unit appended I've seen a script called "NightOwl" at codecanyon that almost does what I'm after, but the "mini calculator" feature doesn't show all of the fields on the page and won't allow me to add a radio buttons.
