title: Radio button group retrieve value
body: <p>I have group radio buttons with same name cost and different id's cost_1, cost_2. and their values are also different. I wish to collect value of selected radio button. and show it in particular text box that is 'total' including values of other radio button group. How can I get value of selected radio button from name using jQuery? Because if I select it using ID and loop it will count value of each radio button. </p>
