How do I limit the number of characters in a textarea?
<script type="text/javascript"> function checkInputSize(which, maxsize) { which.value = which.value.substring(0, maxsize); } </script> <textarea rows="10" cols="30" name="exampleTextArea" onchange="checkInputSize(this, 255)">
Where 255 is the maximum number of characters allowable. JavaScript cannot effectively set a limit on anything. Any browser that supports JavaScript lets the user disable the support too.
