title: Check Input text if empty based upon radio button selected
body: <p>I have two radiobuttons in a group on my page. Based upon radiobutton selected i want to generate an alert.</p>
  
  <pre><code>var d=GetVal();
  
  function GetVal()
  {
  var a = null;
  var f = document.forms[0];
  var e = f.elements["radiogroup"];
  
  for (var i=0; i &lt; e.length; i++)
  {
  if (e[i].checked)
  {
  a = e[i].value;
  break;
  }
  }
  return a;
  }
  </code></pre>
  
  <p>At the time of form validation, It is always returning only first radiobutton value when iam reading it in if else loop.</p>
  
  <pre><code>if (!checkRadio("form","radiogroup")) 
  {
  alert("none of the option was selected"); 
  return false;
  }
  //if one radio option was selected
  else
  {
  if(d="firstradiovalue"){
  alert("first radio selected");
  return false;}
  else{
  if(d="secondradiovalue"){
  alert("second radio Selected");
  return false;}
  }
  }
  </code></pre>
  
  <p>At the time of form submission, even if i choose second option i only get alert - "first radio selected". Any help. Thx in advance.</p>
