urgent.. email validation

[VbUser25]

Hi

Please suggest i think i am doing something wrong. I am calling fucntion
test from another function where i am performing all the validations.I
want to validate the email id.

this is the main function where i perform all sort of mandatory
validation==>
if (document.f.repemail.value != ""){
if(test(document.f.repemail.value=false)) {
alert("Please Enter a valid Email ID!");
document.f.repemail.focus();
}
else {return;}
}


Here is fucntion test:
function test(src)
{ var emailReg = "^[\\w-_\.]*[\\w-_\.]\@[\\w]\.+[\\w]+[\\w]$";
var regex = new RegExp(emailReg);
alert(regex.test(src));
return regex.test(src);
}
I am nto getting validated at all!!! where is hte mistake i am doing.
pls do suggest!

thanks to those who respond.

You must use / instead of " to enclose your regular expression (and probably
use \ instead of \\) :

var emailReg = /^[\w-_\.]*[\w-_\.]\@[\w]\.+[\w]+[\w]$/

Also, I'm not sure if your regular expression is right for testing all valid
email addresses. Testing all possibilities for a valid email address is a
very difficult subject.

This is a ASP [serverside] NG.

if (document.f.repemail.value != "")

That's definitely clientside.

function test(src)

could be serverside jscript,

and if so:
You cannot call a serverside function from clientside
else [as suggested by the alert()]:
Your question is off topic on this NG.

thanks to those who respond.

You're welcome with on topic questions.

thanks a plenty for responding back.

now i got the error rectified but facing another problem :-( this
function works well but somehow when i write a@gdhd it accepts it! i
feel it should search for a "." at least?? am i right in my thots or
not? if i write a@fhh then it gives the error message!
here is hte piece of code:
if (document.f.repemail.value != ""){
if(!(test(document.f.repemail.value))) {
alert("Please Enter a valid Email ID!");
document.f.repemail.focus();
return;
}
}

function test(src)
{ var emailReg = "^[\\w-_\.]*[\\w-_\.]\@[\\w]\.+[\\w]+[\\w]$";
var regex = new RegExp(emailReg);
return regex.test(src);
}

pls pls do sugest..i am confused
thanks

As pointed out, this is an ASP (serverside) newsgroup, whereas you seem
to be posting clientside javascript. If you want help with clientside
javascript, you should find a more appropriate newsgroup to post to.

However... if you want to do serverside email validation, check out the
following two articles:

"Powerful Form Validation Using ASP"
http://www.asp101.com/articles/hojjat/formvalidation/default.asp
This article shows how to check for basic email address requirements.

"Validating Email Addresses with ASP"

This article shows how to use freely available websites to do an MX lookup.
