Select one javascript for radio buttons

I have the javascript below to make sure a user checks at least one checkbox.
Seems to work fine for checkboxes but not for radio buttons. I need help tweaking it so that it works.

I have a repeated region displaying names, they all have ids, I need the user to select one of the radio buttons.

<script language="JavaScript">
function oneCheckboxChecked(form){
for(f=0;f<form.length;f++){
if(form[f].type !="checkbox") continue;
if(form[f].checked){
return true;
}
}
alert("Select at least one User");{
return false;
}
}
</script>

Try this ,

<script language="JavaScript">
function oneCheckboxChecked(form){
for(f=0;f<form.length;f++){
if(form[f].type =="radio") 
if(form[f].checked){
return true;
}
}
alert("Select at least one User");
return false;
}
</script>

<form id="form1" onsubmit="return oneCheckboxChecked(this)">
<input type="radio" name="gender" value="male" > Male<br>
  <input type="radio" name="gender" value="female"> Female<br>
  <input type="radio" name="gender" value="other"> Other

<!--<input type="button" name="button" value="Click" onclick="oneCheckboxChecked(document.getElementById('form1'))">--> 
    
    <input type="submit" name="submit" value="Lets Submit"/> 
    <br>
</form>
