Limit entry into TextArea

[JohnSouth]

Hi

In a TextBox I can set a maximum size for the entry.
Is there a way of limiting the number of characters being entered into
a TextArea control?

<textarea onkeypress="if (this.value.length > 200) this.value =
this.value.substr(0, 200);">
</textarea>

do this on onblur too, to avoid copy paste and if there are other
scenarios to put more too.

Why not limit length of input in the first place?

<textarea onkeypress="return (this.value.length <= 200);"></textarea>

where the parens are not necessary. This should be extended to tell
the user why the number of characters is limited.

It's a javascript topic so I thought he wants a javascript solution

You are talking nonsense. Mine *is* a JavaScript solution as well, which,
in contrast to yours, limits the length of input on the first place rather
than correcting the value afterwards. And any solution for this problem
cannot qualify as a JavaScript solution alone, because the DOM is involved
always.

Thanks to All. It's clear to me now, and it makes a big improvement to
the entry screen.
