jquery expand textbox on focus using

Aug 19, 2012

Here I will explain how to expand or increase textbox size on focus using JQuery in

In previous article I explained disable right click on image using JQuery and many articles relating to JQuery. Now I will explain how to expand or increase textbox size on focus using JQuery in

To implement this one we need to write code as shown below in your aspx page

<html xmlns="">
<title>jquery expand textbox on focus using</title>
<script type="text/javascript" src="">
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#txtUserName').focus(function() {
width: 250,
$('#txtUserName').blur(function() {
width: 150,

<form id="form1" runat="server">
<asp:TextBox ID="txtUserName" runat="server" />
If you observe above code in header section I added script file link by using that file we have a chance to interact with JQuery and in header script we have focus and blur events for txtUserName textbox which is used to animate the texbox to increase or decrease size based on onfocus and onblur. 


To test this sample check below textbox
