Get selected radio button value using JQuery

How to know which radio button is selected from the group of Radio Buttons on button click  using JQuery?

Example – 

I will explain with the help of an example.

Following are the radio buttons tags

  <input type="radio" name="rdNew" id="rdAll" checked="checked" value="0" >All</input>

  <input type="radio" name="rdNew" id="rdNew" value="1">New</input>

  <input type="radio" name="rdNew" id="rdInvoiced" value="3" >Invoiced</input>

  <input type="radio" name="rdNew" id="rdCancelled" value="4" >Cancelled</input>

  <input type="radio" name="rdNew" id="rdPartialInvoice" value="5" >Partial</input>

  <input type="radio" name="rdNew" id="rdPaid" value="6">Paid</input>

Input button Tag– On click we will get the value of Selected Radio Button

 <input type="button" id="btnOrder" onclick="GetSelectedRadionButtonValue();"></input>

  

JavaScript code for getting the selected radio button value.

 

<script language="javascript" type="text/javascript">

function GetSelectedRadionButtonValue ()

{

       var selectedValue = $("input[@name=rdNew]:checked").val();

 }

</script>

 selectedValue is JavaScript Variable  which will return the value of the selected radio button.

You can put this code :  $("input[@name=rdNew]:checked").val();
