This will help you to limit the characters in text field

<script language="javascript" type="text/javascript">
function limitText(limitField, limitNum) {
    if (limitField.value.length > limitNum) {
        limitField.value = limitField.value.substring(0, limitNum);

    <input type="text" id="sessionNo" name="sessionNum" onKeyDown="limitText(this,5);" 
onKeyUp="limitText(this,5);"" />

  1. All the Text and HTML attributes have limitations in their sizes anyway.
  2. It would be possible to create an attribute customization based validator ( ) it would have to get the text value and check its length.
