jQuery Validate plugin - password check - minimum requirements - Regex
- by QviXx
I've got a little problem with my password-checker.
There's got a registration form with some fields.
I use jQuery Validate plugin to validate user-inputs.
It all works except the password-validation:
The password should meet some minimum requirements:
minimum length: 8 - I just use 'minlength: 8'
at least one lower-case character
at least one digit
Allowed Characters: A-Z a-z 0-9 @ * _ - . !
At the moment I use this code to validate the password:
$.validator.addMethod("pwcheck",
function(value, element) {
return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value);
});
This Code works for the allowed characters but not for minimum requirements.
I know that you can use for example (?=.*[a-z]) for a lower-case-requirement. But I just don't get it to work.
If I add (?=.*[a-z]) the whole code doesn't work anymore. I need to know how to properly add the code to the existing one.
Thank you for your answers!
This is the complete code
<script>
$(function() {
$("#regform").validate({
rules: {
forename: {
required: true
},
surname: {
required: true
},
username: {
required: true
},
password: {
required: true,
pwcheck: true,
minlength: 8
},
password2: {
required: true,
equalTo: "#password"
},
mail1: {
required: true,
email: true
},
mail2: {
required: true,
equalTo: "#mail1"
}
},
messages: {
forename: {
required: "Vornamen angeben"
},
surname: {
required: "Nachnamen angeben"
},
username: {
required: "Usernamen angeben"
},
password: {
required: "Passwort angeben",
pwcheck: "Das Passwort entspricht nicht den Kriterien!",
minlength: "Das Passwort entspricht nicht den Kriterien!"
},
password2: {
required: "Passwort wiederholen",
equalTo: "Die Passwörter stimmen nicht überein"
},
mail1: {
required: "Mail-Adresse angeben",
email: "ungültiges Mail-Format"
},
mail2: {
required: "Mail-Adresse wiederholen",
equalTo: "Die Mail-Adressen stimmen nicht überein"
}
}
});
$.validator.addMethod("pwcheck",
function(value, element) {
return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value);
});
});
</script>
