Title:Allow only number of Alphabets in to Text box in using JQuery

As per previous article ,we have done validation on the text box which has to hold some value while doing the insertion.Now i would like describe and give an example on JQuery validation ,which will allow only 10 characters into text box.So here i will put condition text box length while performing the validation i:e is less then 10 ,it will show error message through alert box

<head runat="server">
<script type="text/javascript" src="Javascript/jquery-1.3.1.min.js"></script>
<script type="text/javascript" language="javascript">

$(document).ready(function() {

$('#allowOnlyChars').click(function() {

if ($("#OnlyChars").val().length < 10) {

alert('Valid data'+"#OnlyChars").val());

return true
else {
alert('Please: you should enter only 10 characters')
return false;
<form id="validateForm" runat="server">
<asp:TextBox ID="OnlyChars" runat="server"></asp:TextBox>
<asp:Button ID="allowOnlyChars" runat="server" Text="Validate" OnClick="allowOnlyChars_Click" />
