if (!filter.test(email.value)) {

you can aslo use RegularExpressionValidator

ASP.NET

<asp:regularexpressionvalidator id="regexEmailValid" runat="server" validationexpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" controltovalidate="tbEmail" errormessage="Invalid Email Format" xmlns:asp="#unknown"></asp:regularexpressionvalidator>

Try this:

Java

function validate(form_id,email) {

   var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
   var address = document.forms[form_id].elements[email].value;
   if(reg.test(address) == false) {

      alert('Invalid Email Address');
      return false;
   }
}
