Formance.js

• Limits to 10 numbers
• Restricts inputs to numbers
• Includes ( and ) around the area code
• Includes a - between the prefix (first 3 digits after the area code) and the line number (last 4 digits)

$('input.phone_number').formance('format_phone_number');
            

Validates the phone number:

• Does NOT validate whether the number actually exists.
• Validates length (after stripping away non digit characters)

$("<input value='6131231234' />").formance('validate_phone_number'); // true
$("<input value='(613) 123 - 1234' />").formance('validate_phone_number'); // true
$("<input value='(613) 123 - 12345' />").formance('validate_phone_number'); // false

Formats the date in the dd / mm / yyyy format:

• Limits to 8 numbers
• Restricts input to numbers or slashes depending on the current state
• Includes a / between the day & month and month & year.
• Does NOT accept shorthand to avoid ambiguities

$('input.dd_mm_yyyy').formance('format_dd_mm_yyyy');
             

Validates the date:

• Validates the date can be parsed.
• Validates the date actually exists so it will fail if February 30th is entered even though it passes parsing.

$('input.dd_mm_yyyy').formance('validate_dd_mm_yyyy');
             

Date includes a helper function to retrieve the date value. Note it does not check to see if it is valid. It simply creates a date object with the specified values which may be incorrect. For example new Date(2013, 2-1, 30)returns March 2nd because February does not have 30 days. You should check if it is valid before using the date.

If the text is parsed without any errors then a Javascript Date object is returned otherwise false.

$("<input value='01 / 07 / 2013' />").formance('val_dd_mm_yyyy');   // new Date(2013, 7-1, 1)
$("<input value='dd / 07 / 2013' />").formance('val_dd_mm_yyyy');   // false 

Similar to documentation of dd / mm / yyyy except the format is yyyy / mm / dd.

Before everybody goes on a rant, I agree that the only way to validate an email address is to send it an email. However, some client side validation does not hurt especially since 99% of email addresses won't have multiple @ symbols and be top level domains.

If you want to contribute another email validator by all means do so. It would be helpful to have multiple email validators with varying degrees of coverage.

Validates the email address:

• Validates the email address using the algorithm specified by the data attribute formance_algorithm. By default the simple algorithm is used.
• For now there are only 2 algorithms simple and complex.
• Simple is very lenient and as a result there can be false positives (an email is labelled a valid when it is invalid).
• Complex as the name suggests, is less forgiving and works for 99% cases, but it results in more false negatives (an email address is labelled as invalid when it is valid).

$("<input value='[email protected]' />").formance('validate_email');  // true
$("<input value='[email protected]' data-formance_algorithm='simple' />").formance('validate_email');  // true
$("<input value='[email protected]' data-formance_algorithm='complex' />").formance('validate_email');  // true
$("<input value='postbox@com' data-formance_algorithm='simple' />").formance('validate_email');  // true
$("<input value='postbox@com' data-formance_algorithm='complex' />").formance('validate_email');  // false

Formats the credit card cvc:

• Limits to length of 4
• Restricts input to numbers

$('input.credit_card_cvc').formance('format_credit_card_cvc');
            

Validates the credit card cvc:

• Validates number length between 3 and 4
• Validates numbers
• Checks if the data attribute credit_card_type exists to check if cvc matches that card's standards.

$("<input value='123' />").formance('validate_credit_card_cvc');        // true
$("<input value='1234' />").formance('validate_credit_card_cvc');       // true 
$("<input value='123' data-credit_card_type='amex' />").formance('validate_credit_card_cvc');   // true
$("<input value='1234' data-credit_card_type='amex' />").formance('validate_credit_card_cvc');   // true
$("<input value='12345' />").formance('validate_credit_card_cvc');      // false

$('input.credit_card_expiry').formance('validate_credit_card_number'); 
//examples

$("<input value='4242-4242-4242-4242' />").formance('validate_credit_card_number');   // true 
$("<input value='4242' />").formance('validate_credit_card_number');   // false 
             

This field includes a special helper function to retrieve the credit card type. It recognizes

• visa
• mastercard
• discover
• amex
• dinersclub
