Javascript Regex matching logical or

Question

I am wondering if JavaScript includes the logical or when pattern matching. I would like to check if the user is either using @hotmail.com or @gmail.com, with anything allowed to come before it, and nothing allowed after the @hotmail or @gmail.com. Instead of having to write two separate conditions to check each one is there away to combine it into one test. Thank you.

试试这个正则表达式：

/^(.+)@(hotmail|gmail)\.com$/
