How to retrieve radio button value in Javascript

Question

i want to retrieve the value of radio button, here how they look

"<td width=70% align=left class=WizardBodyFont><input type=radio name=gender id=gender value=""M"" checked>Male" & vbcrlf
        g_strBodyText = g_strBodyText & "&nbsp;&nbsp;&nbsp;&nbsp;<input type=radio name=gender id=gender value=""F"">Female</td></tr>"

I'm trying to retrieve the radio button value based on ID like below in my javascript & its not working.

 gendernode = fraWizard.document.frmWizard.getElementById("gender");

If i try to get the values based on Tag name its working fine

var txts = fraWizard.document.frmWizard.getElementsByTagName("input")

How to retrieve the value by ID.

I think `var value = document.getElementById("gender").value;` should do the trick — Jonas Grumann, Jan 31 '18 at 14:03
What is `fraWizard.document.frmWizard` supposed to be? If there are any iframes or similar in play, then you should tell us. Otherwise, that syntax makes little sense. — CBroe, Jan 31 '18 at 14:03
IDs have to be unique within an HTML document, you can not give both input fields the same one. — CBroe, Jan 31 '18 at 14:04

You can get the value using getElementsByName:

gender_value = document.getElementsByName("gender").value;

Hi, its not working. If i try this, fraWizard.document.frmWizard.getElementsByTagName("input"), i m getting all inputs, but if i try by ID. its failing – Naruto Jan 31 '18 at 14:08
I changed my answer .. sorry. You can user "getElementsByName" instead. I think it should work. – Abdallah Ajlouni Jan 31 '18 at 14:09
And if you can use jQuery, it simply: gender_value = $("input[name=gender]:checked").val(); – Abdallah Ajlouni Jan 31 '18 at 14:15
