Hide Email Address from Unauthorized Users in JavaScript
Hiding an e-mail address
The following steps are to be followed to hide our e-mail from unauthorized users.
- In every email address '@' symbol is common so try to remove it from the email address using split() method. In the following example after splitting the email(batman@gmail.com) we get the result as batman, gmail.com.
- Divide the result in to 2 parts(split1 and split2).
- Using substring() method remove some of string from split1 and join resulted part with split2 using '...@'.
- Return the joined part as the final output. In our example the resulted output is "bat...@gmail.com".
Example
<html>
<body>
<script type="text/javascript">
newEmail = function (email) {
var split = email.split("@");
var split1 = split[0];
var avg = split1.length / 2;
split1 = split1.substring(0, (split1.length - avg));
split2 = split[1];
return split1 + "...@" + split2;
};
document.write(newEmail("batman@gmail.com"));
</script>
</body>
</html>
output
bat...@gmail.com
