I have ASP.NET project and I need to check is email correct or not. I always using that script, but it fails with asp.net, because @ is bad symbol.
function emailvalidate(e)
{
var b=/^[^@\s]+@[^@\.\s]+(\.[^@\.\s]+)+$/;
return b.test(e);
}
How can I fix this? And its important to check email by JavaScript, not ASP.NET or C#.
P.S. Im really new with ASP.NET and JavaScript RegEx.

18-Jan-2015Are you using the Razor view engine? If so you will need to escape those @ symbols if you are adding this script to the cshtml file itself
or you can wrap the regular expression in @Html.Raw as deherch mentioned:
var b = @Html.Raw(@"/^[^@\s]+@[^@\.\s]+(\.[^@\.\s]+)+$/");
you can also add this function to a script file with all your other common JS functions. This way you do not need to escape the razor syntax at all.
Win mentions that you want to use server-side validation. I would say best to use both. Client-side validation can stop it from ever hitting the server in the first place. And server-side validation because you can never trust what a client passes in.
