Change text based on characters in box

Mar 11.2006

[B]Here’s what I need:[/B]

1 textbox (t1)
1 textbox (t2)
1 textbox (t3)

t2 displays the number of characters in t1.

t3 displays an amount in the form of $x.xx or ‘Free’

[B]Simple enough right? Here’s the conditions:[/B]

If t2 <= 100, t3 displays ‘Free’. Otherwise t3 displays $x.xx where it increases by a penny for each character over 100.

[B]Example 1:[/B]

t1 -> aaaaaaaaaaaaaa
t2 -> 14
t3 -> Free

[B]Example 2:[/B]

t1 -> aa…aa (150 a’s)
t2 -> 150
t3 -> $0.50

Thanks for any help you can give!

@phpnoviceMar 11.2006 — This seems like a school assignment. Is it? If so, then if you don't understand how to do your school assignments, you should be asking your teacher for this kind of help. You will benefit in the long run.

If not an assignment, then post some JavaScript and HTML code to show what you're working on. Thanks.

@phpnoviceMar 11.2006 — OK, then I'll just point out that the [b]onkeyup[/b] event is the best for just counting characters in a text box/area as they are typed.

Success!
