textarea length setting

[Bill]

Hi.

Is there any way to set a textarea to a limited number of characters, like
the text element?

PS I'm not talking about line width and num lines, which I know you can set.

Thanks.

<!-- Allows no more than 10 characters -->
<textarea ... onkeyup="if (this.value.len gth > 10) this.value =
this.value.subs tring(0, 10);">...</textarea>

This works in IE 6 SP-1 and Mozilla/5.0 rv:1.5 on Win2k.
But since client-side scripting can be disabled or (partly)
not supported, server-side form checking is also required.

How do get that idea? Line width and number of lines is exactly what you
cannot restrict in contrast to the length of the value. You can merely
define how long a line *should* be *displayed* before the text is *wrapped*
and how many wrapped lines *should* be *displayed* simultaneously without
*scrolling*.

Didn't know that either. Thanks again Thomas...
