This article will show you how you can get the selected
radio button value using jquery in asp.net. In this
I have used control type and then detected which the checked radiobutton value
using jquery
and display in javascript alert box.
Some of my previous articles are as follows: jQuery
Ajax Search and Display In MVC WebGrid in Asp.Net MVC Using C#.Net, jQuery
Drag and Drop Item Functionality In Asp.Net MVC, jQuery
Tabs Collapse Control Using jQuery In Asp.Net MVC, MVC2, MVC3, MVC4 and MVC5,
jQuery
Slider and Range Slider Plugins, Theme
Creation for jQuery Mobile.
So for this article first we will create a new asp.net application and add some radio button on it and give the common grouname so you will be able to select only one radiobutton at a time.
Here is the jquery code.
<script language="javascript">
function
GetValue() {
var
selectedvalue = $("input[type='radio']:checked").val();
alert(selectedvalue);
}
</script>
|
In above code I have detected the value and display in alert
message box. So here is the complete code.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication2.WebForm1"
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD
XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Get
RadioButton Value Using jQuery In Asp.Net</title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script language="javascript">
function
GetValue() {
var
selectedvalue = $("input[type='radio']:checked").val();
alert(selectedvalue);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:RadioButton ID="RadioButton1" runat="server" Text="Radio Button 1 " GroupName="val"
/>
<asp:RadioButton ID="RadioButton2" runat="server" Text="Radio Button 2 " GroupName="val"
/>
<br />
<asp:RadioButton ID="RadioButton3" runat="server" Text="Radio Button 3 " GroupName="val"
/>
<asp:RadioButton ID="RadioButton4" runat="server" Text="Radio Button 4 " GroupName="val"
/>
</div>
<div>
<br />
<asp:Button ID="Button1" runat="server" Text="Get Value" OnClientClick="javascript:GetValue();" />
</div>
</form>
</body>
</html>
|
Now we have done run the application to check the output.
