Different results in "I forgot the email"

On a website, when the "Forgotten Email" page opens, a text box appears for the email entry, but when it is in that text box, some scripts or entries like: & # 39; O & # 39; 1 & # 39; = & # 39; one is filled in, only a simple & # 39; tic & # 39; in the shipping box, but in the case of an email, simply send the mail and go to another page.

Does that mean you are processing the scripts written on it? But is not any change happening like a pop-up alert window or something like that?
