Hi raja,

Code :
function validateForm() {
    var x = document.forms["myForm"]["email"].value;
    var atpos = x.indexOf("@");
    var dotpos = x.lastIndexOf(".");
    if (atpos<1 || dotpos=x.length) {
        alert("Not a valid e-mail address");
        return false;
    }
}

Hi,

Use this function -

function checkEmail() {      var email = document.getElementById('txtEmail');     var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;      if (!filter.test(email.value)) {     alert('Please provide a valid email address');     email.focus;     return false;  }
