Getting the selected radio without using “Id” but “name”

Question

I was trying to get selected radio button by using \"document.getElementByName(\'nameOfradio\')\" because all of the radio buttons share the same name. But, nothing happened

Answer 1

This is exactly why you should use a javascript library.

document.querySelector('input[name=nameOfradio]');

for example is not supported before IE8.

Let the library handle the browser craziness.

In jQuery you can just use $('input[name=radioName]:checked').val() or $("form").serialize() and be done with it.
