I know this is an old question, but the answers given seem overly complex.

As pointed out earlier, you should not have two elements with the same id. That violates the html spec. Just remove the id attributes, or make them two different values. Then simply use this to get the checked value:

document.querySelector("input[type='radio'][name='u_type']:checked").value
