  Try this javascript Code to validate email
  
  if (emailid == null || x == "") {
  document.getElementById("LabelValidateEmail").innerHTML = "Email Required";
  count++;
  }
  else {
  alphaExp = /^[\w\.=-]+@[\w\.-]+\.[\w]{2,3}$/; //regular expression of a valid email address
  if (!x.match(alphaExp)) {
  
  document.getElementById("LabelValidateEmail").innerHTML = "Check the Email format";
  count++;
  } else {
  document.getElementById("LabelValidateEmail").innerHTML = "";
  }
