Implementation of the Luhn 10 algorithm to check validity of credit card numbers. See http://en.wikipedia.org/wiki/Luhn_algorithm for details on the algorithm.
var validCreditCard = function(a,b,c,d,e){for(d=+a[b=a.length-1],e=0;b--;)c=+a[b],d+=++e%2?2*c%10+(c>4):c;return!(d%10)};
validCreditCard('378282246310005'); //=> true
validCreditCard('378282246310006'); //=> false
// some numbers to test with
// 378282246310005 371449635398431 378734493671000
| var els = document.querySelectorAll('a'); | |
| els.forEach(function(e){console.log(e.href);}); // TypeError: els.forEach is not a function | |
| // Why? | |
| // document.querySelectorAll returns a NodeList. | |
| // First thing first, as opposed to other NodeList, this one is not live, mostly because the | |
| // implementation of a live object would be terribly complicated for some selectors | |
| // NodeList are a DOM interface introduced in DOM core level 1 (random guess) |
| // First, let's define a widget/plugin called "foo" | |
| // Either using jQuery's $.fn plugin namespace, for simple stateless plugins... | |
| $.fn.foo = function(){ | |
| // In this scope, this refers to the element on which the plugin foo() was called | |
| // manipulate it and return this at the end, so it can be chainable | |
| }; |
