  var par = new Array();
  var form = $('mytestForm');
  var y = form.getInputs('radio', 'radioId');
  if ($('radioId1234').checked == true || $('radioId5678').checked == true) {
   
    wmGlobalObj.remErrAdvice();
    par[0] = $F(y.find(function(re) {
      return re.checked;
    }));
    if (paras[0] == '1234') 
      

      window.open('https://www.google.co.in/', 'FirstSearch', 'width=460,height=250', 'testsrch');
    else if (par[0] == "5678") 
      window.open('http://www.bing.com/', 'SecondSearch', 'width=460,height=50', 'testsrch');
    }
  } else {
    alert("error")
  }

You probably can do this alot simpler by just using CSS selectors.

For example

var checked_inputs = $$('form#mytestForm input[type="radio"]:checked');

if(checked_inputs.length > 0)
{
       if(checked_inputs[0].value == "1234")
       {
           window.open('https://www.google.co.in/', 'FirstSearch', 'width=460,height=250', 'testsrch');
           //this exits the foreach loop
       }
       else if(checked_inputs[0].value == "5678")
       {
           window.open('http://www.bing.com/', 'SecondSearch', 'width=460,height=50', 'testsrch');
       }
}
else
{
    alert('error');
}
