ios Javascript history.go(-1)不适用于ios 10.2.1中的Safari

I use php to check email format and use Javascript to alert but I use history.go(-1) it redirect in url/undefined

this is my code

if (!filter_var($mail, FILTER_VALIDATE_EMAIL)) {
$message = "Email format not true";
echo "<script type='text/javascript'>alert('$message');window.location = history.go(-1); </script>";
}

thanks for all your help

    window.location = history.go(-1);
    

    Is wrong. It should be:

    window.history.go(-1);
