Calculations within a form

Copy linkTweet thisAlerts:
Mar 30.2004

Good day,

Being new to javascript I have run into a problem with a form I’m creating. Basically I want to take input from one textbox(number1) perform a calculation then display it in another textbox(number2). Also, based on that value (number2), I want a textbox (number3) to display a different value.

Here is the form I’m working on. The input from the Numbers textbox(number1) is calculated then displayed in the Hours textbox(number2). Then based on that number in the Hours text box it goes down to the Estimate textbox(number3).

Any help, code, example whould be much apprecaited. I have been stuck on this for awhile.

Thank you.

@96turnerriMar 30.2004 — you need to refernece these three textboxes

var a = document.form.textboxonename.value;

var b = document.form.textboxtwoname.value;

var c = document.form.textboxthreename.value;

b = a * 2;

c = b - 2;

something like that would be the function your are after

I think that is the logic I'll need for this form.

[B]stop spamming fredmv[/B][/QUOTE]I'll take it you're just kidding, though remember that sarcasm doesn't go very well through text. I was merely welcoming the new user to the forums and ensuring them that we could help them further if need be, primarily because you haven't really provided them with enough detail.

@steelersfan88Mar 30.2004 — and also since the OP stated he was a beginner, he/she may not know how to return a value, especially as it is stoed in a variable (these are not by value subs ?). I find it necessary to explain the whole process if asked, and therefore feel the fred did thje right thing in welcoming the user and making him feel hospitable ?
