Question

Say I have a function similar to this:

  function getGroupValue(group)   {      for (var i=0; i < group.length; i++)       {         if (group[i].checked)          {            return group[i].value;         }      }   } 

that i can call with something like getGroupValue(document.forms[0].myGroup)

How do I convert this to just passing in the name of a html radio button group like getGroupValue('myGroupName') ?

This should work:

 function getGroupValue(group)  {  var g = document.getElementsByName(group);   for (var i=0; i < g.length; i++)   {     if (g[i].checked)      {        return g[i].value;     }  }  }
