Email address validation 2

[Fris]

I have incorporated this code (found on Tek-Tips but I can't remember who originated it) into my form and it works well if an invalid address has been entered:

str=form1.Email.value;
filter=/^(\w+(?:\.\w+)*)@((?:\w+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i
if (filter.test(str)!=true)
{
alert("Please input a valid email address!"
event.returnValue=false;
return

What would be the best way to manipulate this code to allow for a totally blank field? I have tried several things with no success.

Thanks!
Christine

before this conditional statement start a new one
if(frmField.value == "&quot {
return true;
}

that will return control if the field is emnpty and not run the regex test.

if ( ( filter.test( str ) != true ) && str.length != 0 )

should work. Haven't tested it though.
