This simple javascript will do the trick:
<TEXTAREA NAME="text" COLS=50 ROWS=10 class="form"
onKeyDown="LimitText(this.form.text);"
onKeyUp="LimitText(this.form.text);"></TEXTAREA>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function LimitText(field) {
if (field.value.length > 500){
field.value = field.value.substring(0, 500);
alert("Sorry, messages cannot be any longer than 500 characters.");
}
}
// End -->
</script>

Subject: counting words in a textarea
greetings list,
I need to count the words in a textarea and validate client side that it
doesn't exceed a certain number.
We have been trying to use regular expressions to count the words. Is
there a way to count the words in a string and return the number of
words
to test against this value. We would then trim out the extra words and
send them back to the form.
We have it working using indexOf and only checking for spaces, but run
into
problems when there are tabs in the textarea.
thanks and kind regards,
Jeffrey
