You can build this function as per your requirement.
function isEmail(frm,obj,txt)
{
var fld=frm[obj];
var str = fld.value;
if (str.indexOf(',',0) != -1) {
alert ("You Cannot Have a comma In Your Email Address..");
// fld.value=""
fld.focus();
return false;
}
else if (str.indexOf('/',0) != -1) {
alert ("You Cannot Have a \" / \" In Your Email Address.");
// fld.value=""
fld.focus();
return false;
}
else if (str.indexOf('+',0) != -1) {
alert ("You Cannot Have a \" + \" In Your Email Address.");
//fld.value=""
fld.focus();
return false;
}
else if (str.indexOf('@',0) == -1) {
alert ("You must enter a fully qualified email address (e.g. sales@yourwebsite.com).");
//fld.value=""
fld.focus();
return false;
}
else if (str.indexOf('.',0) == -1) {
alert ("You must enter a fully qualified email address (e.g. sales@yourwebsite.com).");
// fld.value=""
fld.focus();
return false;
}
else if (str.indexOf(' ') != -1) {
alert ("You must enter a fully qualified email address (e.g. sales@yourwebsite.com).");
// fld.value=""
fld.focus();
return false;
}
else { return true; }

function isEmail() {
emailRegex = /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
var emailid = document.getElementById('txtEmailId').value;
if( !emailid.match( emailRegex ) )
{
alert( 'Please enter a valid Email Id' );
document.getElementById('txtEmailId').focus();
return false;
}
return true;
}
It works both in IE and FireFox. |

Hi,
function ValidateEmail(strEmail)
{
var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (filter.test(strEmail))
{ // nothing
return true;
}
else
return false;
} |
