    if(!firstpassword.match((/^(?=.\d)(?=.[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/))) {
    alert("Password must be Alphanumeric");
    return false;
    }

    ^(?=.\d)(?=.[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$
    How can I limit the above expression to just aphanumeric and regardless of case?

    Shouldn't be like this?

    if(/^(?=.*[A-Z])(?=.*[a-z])(?=.*\d).*$/.test(document.regForm.password.value)) {
    alert("Password must contain an Alphabet(Upper ), Number,");
    document.regForm.lastname.focus();
    return false;
    }

    alert("Password must contain an Alphabet");
    document.regForm.password.focus();
    return false;
    }
    //minimum password length validation
    if(firstpassword.length < 8){
    alert("**Password length must be atleast 8 characters");
    return false;
    }
    //maximum length of password validation
    if(firstpassword.length > 15) {
    alert("**Password length must not exceed 15 characters");
    return false;
    }
    /*
    if(secondpassword==null || secondpassword==""){

    return false;
    }*/
