Radio Buttons

Sample radio buttons show selection

Here is the HTML for the radio buttons group and the "show selection" link:

For radio-buttons, you can use: $('input:radio[name=RadioButtonsName]:checked').val()

In this example, I pass the name of the radio-button group into the function and "alert" the result. You could easily change this to "return" the value or assign the value to a variable.
