验证用户注册表

Question

我有一个用户注册表。我已经使用验证来检查是否填写了所有字段。我需要使用 javascript 验证电子邮件和手机号码，如果无效，请使用警报框发出警报。请帮忙

代码是

            var name = $("#name").val();
            var inst = $("#inst").val();
            var email = $("#email").val();
            var mobile = $("#mobile").val();
            var dataString = 'name='+ name + '&inst='+ inst + '&email='+ email +'&mobile='+ mobile;
            if(name==''|| inst=='' || email=='' || mobile=='')
            {
            alert("Please Enter all the Fields");
            }
else 
{ //rest of code comes here

Answer 1

var emailRe = /^w+([.-]?w+)*@w+([.-]?w+)*.(w{2}|(com|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$/;
var phoneRe = /^((+d{1,3}(-| )?(?d)?(-| )?d{1,5})|((?d{2,6})?))(-| )?(d{3,4})(-| )?(d{4})(( x| ext)d{1,5}){0,1}$/;
var email_address = $('#email').val();
var phone_number = $('#phone').val();
if(emailRe.test(email_address) === false){
  alert(email_address + ' is invalid');
}
if(phoneRe.test(phone_number) === false){
  alert(phone_number + ' is invalid');
}
