After attempting to bribe people to do this for me, I actually made some progress on my own:

By god I am starting to actually understand this!

There...

LOL.. sometimes coding late at night is not the best idea. After racking my brain for a good hour, I realized that finding a charge by percent is a mathematical impossibility (unless I am calculating...

Argh.. I been trying to hook this up so that I can also type inside the percentage field and have that deduct the charge field (will do profit too once I figure this out) So far I havent been...

Thanks for taking the time to explain.. you make it sound so easy!

I suppose my problem with examples like these is that I tend to prefer explicit over clever code. I program in Ruby so maybe that...

Thanks for the code John..I cant believe how small a footprint it has. Of course I cant understand a word of it :P.

Trinithis's solution was more verbose, but I managed to twist it to suit my...

I have one last fish to fry before I go modular.

This one is truly baffling



var vdiscount = discount.value.trim();
var ndiscount = 1 - ((vdiscount*1)/100);

subtotal.value =...

Woops!

After testing this out thoroughly its not working just yet. Im still stepping on my own toes it seems and the calculations are not accurate when I add multiple events.

Gonna sleep on...

Actually, now that this is working, I have one last question.

At some point I will need to have multiple rows of these fields and I'm wondering how I can make this code more dynamic..IOW somehow...

Got it!


addEvent(
[cost, percent],
"keyup",
function(f) {
var vcost = cost.value.trim();
var vpercent = percent.value.trim();
var ncost = vcost*1;

Wow.. you certainly write some lovely code there. So clear and easy to follow!

It works a charm, although now just out of curiosity I wonder if I can extend it so that typing in a percentage will...

An image is worth a thousand words so:

I basically want to have the user input the first two fields and have the last two get automagically calculated.
