Jquery正则表达式验证邮箱 手机的格式

function checkEmail(email) {
var re = /^[a-zA-Z0-9]{1}[\\.a-zA-Z0-9_-]*[a-zA-Z0-9]{1}@@[a-zA-Z0-9]+[-]{0,1}[a-zA-Z0-9]+[\\.]{1}[a-zA-Z]+[\\.]{0,1}[a-zA-Z]+$/;
if (re.test(email)) {
return true;
} else {
return false;
}
}

或

  var mobileReg = /^1[34578]\d{9}$/;

var mobile = $.trim($("#txtconsignerMobile").val());

if (mobile == "" || !mobileReg.exec(mobile)) {
popBox(\'"@Html.GlobalResources("Gift.请输入正确的手机")\', "");

return false;
}
