Answer 1

将email.lastIndexOf("@") === 0到您的条件中，如下所示：

if(email.lastIndexOf("@") === 0 || !(email.endsWith("@yahoo.com") || email.endsWith("@gmail.com"))){

Answer 2

Try with this kind of regexp

if (email.match(/^\S+@(yahoo|gmail)+\.com$/g))

This will check that you have content before the @ and validate that is it yahoo or gmail.
