Searching the internet I found the following e-mail validation routine:
function isValidEmailAddress( address )
{
return String(address).match(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,7})+$/);
}
Feed the following (invalid) address to the routine
123456789012345678901234567890abcdefg
Result:
IE hangs, need a complete browser restart!! Maybe you need to be very very patient!
Firefox detects a slow script
I think this is pretty strange!!
