jayphelps / retry-with-replace.js
Created May 9, 2014 21:40
Common poorly documented Ember.js apis, tasks, conventions, etc. Some of these are private APIs! USE AT YOUR OWN RISK.
// Retry route Transition, but replace the URL state; just like router.replaceWith('route.name');
abortedTransition.retry().method('replace');

Validates an email, error on the side of letting bad ones through (best practice). Accepts emails with plus signs.
function isValidEmail(str) {
/**
* These comments use the following terms from RFC2822:
* local-part, domain, domain-literal and dot-atom.
* Does the address contain a local-part followed an @ followed by a domain?
* Note the use of lastIndexOf to find the last @ in the address
* since a valid email address may have a quoted @ in the local-part.
* Does the domain name have at least two parts, i.e. at least one dot,
* after the @? If not, is it a domain-literal?
