JQuery: How to determine if a radio button has been selected?

Question

How can I determine if my radio buttons are selected?

For example:

if ( radio_button_selected ) {

// do something

} else {

// do something else

}

Answer 1

You can use this selector to determine if any are checked:

jQuery("input[name='my_button_group']:checked")

So for example:

if (jQuery("input[name='my_button_group']:checked")) {
    ...
}
else {
    ...
}
