 var emailReg = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;

This is my regular expression . it accepts the email such as

 name.name_@__domain.in

How can i format my regular expression which accepts only a valid email format only. I need the email validation for above example.it is not a duplicate one.

  var emailReg= /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;

the expression you prefer accepts ...name@domain.com

            var expr = /^(\w+)([\.])(\w+)@(\w+)([\.])in$/;
            return expr.test(email);
        };
        function ValidateEmail() {
            var email = document.getElementById("txtEmail").value;
            if (!IsValidEmail(email)) {
                alert("Invalid email address.");
            }
            else {
                alert("Valid email address.");
            }
        }
    </script>
</head>
<body>
