My javascript validation for my email, dosen't work

Question

we've made a validation in javascript. firs and second name validation works, but not the email in another project, it does work, but you can't "send it" we would be really happy if anyone knows how to solve this problem,

the code looks like this:

function validateRegUserInsert() {
    firstname = document.getElementById("firstname");
    lastname = document.getElementById("lastname");
    email = document.getElementById("email");
    pwd = document.getElementById("pwd");


    if(validateName(firstname.value)){

    } 
    else {
        alert("Se till att ditt förnamn inte innehåller siffror eller att fältet är tomt!");
        return false;
    }

    if(validateName(lastname.value)){

    } 
    else{
        alert("Se till att ditt efternamn inte innehåller siffror eller att fältet är tomt!");
        return false;
    }

    if(validateEmail(email.value)){

    } 
    else{
        alert("Se till att skriva en giltig emailadress!");
        return false;
    }

    if(pwd.value.length > 5){

    } 
    else{
        alert("Ditt lösenord måste innehålla minst 6 tecken!");
        return false;
    }
    regUser();
    return false;   
}



function validateName(name) { 
    var re = /^[a-zA-ZàáâäãåąčćęèéêëėįìíîïłńòóôöõøùúûüųūÿýżźñçčšžÀÁÂÄÃÅĄĆČĖĘÈÉÊËÌÍÎÏĮŁŃÒÓÔÖÕØÙÚÛÜŲŪŸÝŻŹÑßÇŒÆČŠŽ∂ð ,.'-]+$/;
    return re.test(name);
}


function validateEmail(email) { 
    var re = /^(([^<>()[\]\\.,;:\s@\]+(\.[^<>()[\]\\.,;:\s@\]+)*)|(\.+\))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(email);
    }

Answer 1

your regex doesn't work maybe:

try this one:

function validateEmail(email) { 
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(email);
}
