[thelist] Email Validator

[Maryanna Nesina]

I agree with Shaun :)
my own variation for that perpouse sometimes ago was jast:


 if((err==0) && (((e.name=="emale") &&( (e.value.indexOf("\@") < 1) ||
((e.value.length)  (= (e.value.indexOf("\@")+ 1) ))))) err=1;
 // if e-male field and (&&) ( it doesn't contain @ or anuthing before @ or
(||) nothing goes after @)
    if (err == 1) break;
 }
   if (err==0) {
     return true;
   }

whrer var f - the Form name and  for (var i = 0; i < f.length; i++) {
                                                                 var e =
f.elements[i];
...

I think that the goal of JavaScript in this case is to help user if he
ocasionally do some mistakes, not to prevent him from submiting invalid
address.
If it's necessory we can go on checking on the server side (using dns ets.
ets.)
But the best way is to ask for e-mail confirming. (Thou I do undestend that
the Regex task itself was rather splended :)))
