Change \A and \z to ^ and $ in regex

[jokklan]

Hey

I tried to add a email validator to my application, based on the rails guides on validations, like this:

validates :email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i }

The problem is that javascript doesn't seem to support \A (start of string) and \z (end of string), but only ^ (start of line) and $ (end of line). However i can't use that in my validation, because rails will throw a error telling me to use the multiline options, which is not really what i want.

I made this small fix, that replaces \A with ^ and \z with $. This would properly be temporary if you still plan on implementing a XRegExp plugin, but it was the one most important difference between regex in ruby and javascript I could find :)

@joecorcoran this solves the regex issue in ruby. The solution works perfectly. I suggest to merge it.

👍 on this. I am a new user and had to immediately make this fix yesterday for one of our applications. This is essential in Rails 4 since ^ and $ cause security problems and are flagged by Rails.

Works nicely for me too actually. I tested it with Rails 4.2.1 👍

I will find some time tomorrow and write a spec for this.

@saurabhbhatia #14 and #34 both solve the regex issue too, but I'm leaning towards this one because the others have diverged more. A test here would be great!

Thanks @jokklan! I pulled your commit into #60 and added test cases to it. Will merge as soon as Travis is green.
