Change Textbox Background And Border Color on Focus,on Blur using jQuery In Asp.net

In this article i will show you how you can change the background color of a textbox in asp.net using jquery.
For  this you needed to create a css style. Just check the below style sheet. Add this style sheet at the header of your page.

<style type="text/css">
.focus {
border: 1px solid green;
background-color: yellow;
}
</style>



Now on your add the jquery reference .


<script type="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">

Now add as aspx textbox 



<asp:TextBox ID="txtcountry" runat="server"/>
Now copy the below jquery code at the header of your page.


<script type="text/javascript">
$(document).ready(function() {
$(`INPUT[type="text"]`).focus(function() {
$(this).addClass("focus");
});

$(`INPUT[type="text"]`).blur(function() {
$(this).removeClass("focus");
});
});
</script>

in above code we have applied the style sheet to textbox on focus of the mouse and remove the css on blur event the moue from textbox.

Now after combing the code you page will look as shown below.



<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Change textbox background color on focus in jquery</title>
<script type="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">
</script>
<script type="text/javascript">
$(document).ready(function() {
$(`INPUT[type="text"]`).focus(function() {
$(this).addClass("focus");
});

$(`INPUT[type="text"]`).blur(function() {
$(this).removeClass("focus");
});
});
</script>
<style type="text/css">
.focus {
border: 1px solid green;
background-color: yellow;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>

<
asp:TextBox ID="txtcountry" runat="server"/>

</div>
</form>
