Try this:

XML

<!DOCTYPE html>
<html>
<body>
<form action="" method="post" onsubmit="return validate();">
<input type="text" id="txt_name">
<input type="text" id="txt_reg_no">
<input type="submit" name="submit" value="submit">
</form>
<script>
function validate() {
  Name = document.getElementById("txt_name").value;
  regno = document.getElementById("txt_reg_no").value;

  var isValid = true;
  var reg1 = new RegExp("^[a-zA-Z]+$");
  var reg2 = new RegExp("^[a-zA-Z0-9]+$");

  if (Name == "" && regno == "") {
     alert("Enter name and registration");
     isValid = false;
  } else if (Name == "") {
     alert("Please Enter name");
     isValid = false;
  } else if (!reg1.test(Name)) {
     alert("Invalid Name Entered");
     isValid = false;
  } else if (regno =="") {
     alert("Please Enter Registration Number");
     isValid = false;
  } else if (!reg2.test(regno)) {
     alert("Invalid Registration Enter");
     isValid = false;
  }

  return isValid;
}
</script>
</body>
</html>
