使用以下功能进行电子邮件验证.这也将验证域值.例如以下功能将仅验证以yahoo.com和gmail.com为域的电子邮件.

Use following functions for email validation. this will also validate domain values.. e.g. below functions will only validate emails having yahoo.com and gmail.com as domains.

function validate()
    {

var pattern=/^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z])+([a-zA-Z])+
