[thelist] limit the size on entry on multiline text areas

[spinhead]

What about this?

function charsLimit(charsToCount, CountField, Limit) {
if (charsToCount.value.length > Limit)
charsToCount.value = charsToCount.value.substring(0, Limit);
else
CountField.value = Limit - charsToCount.value.length;

And in the textarea -
onKeyDown="charsLimit(this.form.Comments,this.form.chars_left,256);"
onKeyUp="charsLimit(this.form.Comments,this.form.chars_left,256);"

And finally, a little box to display how many characters you've got 'til it
explodes:
<input readonly type=text name=chars_left size=2 maxlength=3 value="256"
onClick="this.blur()">

(Don't remember why I have both keydown and keyup)
