Edit RegEx Expression in Javascript

I have the following two RegEx expressions in Javascript. The first was found on Microsoft's website, the other on another website. However they both have problems: 1) The first RegEx does NOT allow the symbol + in the e-mail address (instead that symbol is valid) 2) The second RegEx allows ; and : at the end of the e-mail address So, please choose one RegEx and fix it. I'd prefer the first one because it seems more complete. 1) var regexEmail = /^(("[\w-\s\+]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i; 2) var regexEmail = /[a-z0-9!#$%&'*+/=?^_{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/i; PLEASE NOTE: MAX BID PRICE IS $10
