Introduction:
Using Jquery we can check
whether Radiobutton is selected or not. This can be done by using server side
code but using jquery it is fast and easy to implement.in this article I will explain how to use jQuery to check if radio button checked / selected or not. There are different methods to check whetehr radio button is selected / checked or not. By using radio button properties prop or attr.
I have discussed three Method
to find out whether radiobutton is selected or not:
Method 1:
var status = $('#rdbcheck:checked').val() ? true : false
Method 2:
var status = $('#rdbcheck').is(':checked');
Method 3:
var status = $('#rdbcheck').attr('checked') ? true : false;
