Simple calculation (adding) in javascript

[ap.sakala]

Hello,

How the heck should I make this simple summering of a data without a
submit button?

Like in an excel sheet I would like to have a couple of cells in a
column and as soon the visitor types the number the sum should change,
regardless of how many raws there are and based on the setting
(adding, multiplying etc).

I would appreciate the code, link to the code or suggestions.

Thanks in advance. :)

You can use the (on)keypress event to capture the numbers the user
types. The easiest way is to simple write

yourInputElemen t.onkeypress = yourOnkeypressF unction;

where yourOnkeypressF unction is a function that processes the event.

Thanks but I would appreciate the exempel.

Does anyone knows of the script where this is working?

It's very easy to do, so I suggest you give it a try and learn, rather
than bodging something together from examples.

All you have to do is write a simple couple of line function to read the
value from input elements, add them and set the value of another. Bind
these to the element's onkeypress or onchange attributes and you are
done. A very good learning exercise, your textbook will show you how.

Does that site also explain how to quote on Usenet? And I would hate to
know I had to write that much bloated code to do what it does. But, you
got what you paid for.

Why so much negative energy?

Instead you could be more productive and type your code
that is better and more usefull than this one (that works just fine
btw) :)
