use a plugin like this one:

then you can do somethign like this:

$("#myform").validate({
  rules: {
    field: {
      required: true,
      email: true
    }
  }
});

or this

$("#<%=txtEmail.ClientID %>").rules("add", {
        required: true,
        email: true,
        messages: {
            required: "Email is a required field.",
            email: "Email - Invalid email address"
        }
    });

Check this plug-in out.

Not really worth it if you only want one validation though, in my opinion. So you might be better off with some REGEX validation for it.
