XSJS getting result from stored procedure in a variable

I have a situation where I pass a session user as a parameter to stored procedure and get a receiver value which I want to get in a variable so I can pass that to other function in xsjs file to send email.
I am getting sender from session user and doing concat to get sender email.
I am calling ReadAuditUser stored procedure will see if the appuser(session user) is valid or not
if ReadAuditUser stored procedure finds appuser as a valid user then stored procedure will return a single record which will return receiver,
if ReadAuditUser stored procedure finds appuser as a invalid user then the stored procedure will return 'null'.
I want to capture that receiver from getReceivername(), like I have capture appuser from getUsername()function.
Please let me know where I am going wrong.
function getUsername() {
var username = $.session.getUsername();
return username;
}
var appuser = getUsername();
var str2 = "#abc.com";
var sender_email = appuser.concat(str2);
function getReceivername() {
var xreceiver = "";
var conn = $.db.getConnection();
var query = 'call \"AA\".\"PROCEDURE::ReadAuditUser\"(?)';
var pstmt = conn.prepareCall(query);
pstmt.setString(1, appuser);
pstmt.execute();
var rs = pstmt.getResultSet();
if (rs.next()) {
if (rs.getString(1) === 'null') {
xreceiver = rs.getString(1);
} else {
xreceiver = rs.getString(1);
}
}
}
rs.close();
pstmt.close();
conn.close();
var receiver = getReceivername();
var str1 = "#abc.com";
var receiver_email = receiver.concat(str1);

function getUsername() {
var username = $.session.getUsername();
return username;
}
var appuser = getUsername();
var str2 = "#abc.com";
var sender_email = appuser.concat(str2);
function getReceivername() {
var xreceiver = "";
var conn = $.db.getConnection();
var query = 'call \"AA\".\"PROCEDURE::ReadAuditUser\"(?)';
var pstmt = conn.prepareCall(query);
pstmt.setString(1, appuser);
pstmt.execute();
var rs = pstmt.getResultSet();
if (rs.next()) {
if (rs.getString(1) === 'null') {
xreceiver = rs.getString(1);
} else {
xreceiver = rs.getString(1);
}
}
return xreceiver; /* have to add this code line and it works*/
}
rs.close();
pstmt.close();
conn.close();
var receiver = getReceivername();
var str1 = "#abc.com";
var receiver_email = receiver.concat(str1);

How to persist data in an array even when the page reloads, using javascript?

I have created a register and a login form using html and javascript. Where I am storing the user data in an array and then in local storage. For this I have initially declared an empty array called var users=[];
Thus, when the page reloads the previously stored data is lost as array becomes empty again and data in the local storage is overwritten. Please help, on how to avoid the array become empty after reloading the page.
Following is my controller.js-
//Declaring an empty array
var users = [];
//Setting id for each users
var idInput = makeCounter();
//Fetching data from textboxes in register.html
var firstnameInput = document.getElementById("firstname");
var lastnameInput = document.getElementById("lastname");
var emailInput = document.getElementById("email");
var usernameInput = document.getElementById("username");
var passwordInput = document.getElementById("password");
var dobInput = document.getElementById("dob");
var messageBox = document.getElementById("editeddata");
//Declaring custom constructor function
function userdetails(id, firstname, lastname, email, dob, username, password){
this.id = id;
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
this.dob = dob;
this.username = username;
this.password = password;
this.FullName = this.firstname +' ' + this.lastname;
}
//counter funtion, to fetch user id
function makeCounter() {
var arraylength=users.length;
return function(){
return arraylength+1;
}
}
//insert data while registration
function registerUser()
{
//Email validation
var emailinput = document.forms["myform"]["email"].value;
var emailReg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if(!(emailinput).match(emailReg) || emailinput=="")
{
alert("Not a valid e-mail address");
return false;
}
//check, if fields are empty
if(firstnameInput.value=="" || lastnameInput.value=="" || passwordInput.value=="" || dobInput.value=="")
{
alert("Fields cannot be empty");
return false;
}
//check, if a user already exist
var usernameinput = document.forms["myform"]["username"].value;
var passwordinput = document.forms["myform"]["password"].value;
var ulen= users.length;
for(i=0; i < ulen; i++)
{
if ( usernameinput == users[i].username && passwordinput == users[i].password)
{
alert("User already exists");
return false;
}
}
var user=new userdetails(idInput(),firstnameInput.value, lastnameInput.value, emailInput.value, dobInput.value, usernameInput.value, passwordInput.value);
users.push(user);
alert("Registered successfully");
localStorage.setItem("key_users", JSON.stringify(users));
}

You can use local storage value at the time of initialisation.
if (typeof(Storage) !== "undefined") {
if (localStorage.key_users) {
users = localStorage.key_users;
} else {
users = [];
}
}

you can use something like this to check if the key is already in localStorage or not.
<html>
<head>
<link href="style.css" rel="stylesheet">
</head>
<body onload="test()">
<script>
function test(){
var value = (localStorage.getItem("key1"))
console.log(value)
if(value == null){
localStorage.setItem("key1","value1")
alert("Hellow")
}else{
var value=localStorage.getItem("key1");
alert(value)
}
}
</script>
</body>
</html>

How to allow validation for multiple email addresses using javascript

I am using javascript to validate my page, I have done the validation for email which should follow the basic rules of email id. But I need the validation to allow multiple email addresses. Can anyone please help in adding this. Thanks in advance.
Here is JS Code:
function function1(){
var exp = /^(([^<>()[\]\\.,;:\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,}))$/;
var emailid = document.getElementById('mailid').value;
if(emailid == '' || emailid == null){
document.getElementById('error4').innerHTML = "* Enter Email ID";
document.getElementById('mailid').focus();
return false;
}else{
document.getElementById('error4').innerHTML = "";
}
if (!exp.test(emailid)) {
document.getElementById('error4').innerHTML = "* Invalid Email";
document.getElementById('mailid').focus();
return false;
}
}

You could do something like this:
var emails = emailid.split(",");
emails.forEach(function (email) {
if(!exp.test(email.trim()) {
document.getElementById('error4').innerHTML = "* Invalid Email";
document.getElementById('mailid').focus();
return false;
}
});

You should split your emailid string into an array and then check the emails one by one
var emails = emailid.split(',');
You can know more about the split method here http://www.w3schools.com/jsref/jsref_split.asp

Assuming the addresses are separated by comma you could do something like this:
(untested but you should get the idea)
var theString = "an.address#domain.ext, an.other.address",
stringProper = theString.replace(/\s/g,''),
addresses = stringProper.split(','), //creates an array of every email
allValid = true;
for (var i = addresses.length - 1; i >= 0; i--) {
if (addresses[i] == 'an.other.address') {
isValid = true;
} else {
isValid = false;
}
if(!isValid) {
allValid = false;
break;
}
};
function isEmail (theString) {
var exp = /^(([^<>()[\]\\.,;:\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 exp.test(theString)
}

How to make a simple webpage register form using cookies? (jQuery)

I'm making a register/login form in javascript. User should enter information about himself and the computer should put that information into an array and remember it but it 'forgets' it every time I reload the page.
else {
document.cookie = email;
cookies[cookies.length] = document.cookie;
$('#error').text("Your registration is complete.");
break;
}
...more code
$('.btn').click(function() {
alert(cookies[cookies.length - 1]);
});
Any ideas to solve this? I have one more question. How can I check weather is an username alerady in use?
Here is the full js code:
var main = function() {
var people = [];
var cookies = [];
$('#register_email').val("");
$('#register_username').val("");
$('#register_password').val("");
$('#register2_password').val("");
function Person(username, email, password, repeat_password) {
this.username = username;
this.email = email;
this.password = password;
this.repeat_password = repeat_password;
}
$('#register').click(function() {
var username = $('#register_username').val();
var email = $('#register_email').val();
var password = $('#register_password').val();
var r_password = $('#register2_password').val();
if( email==="" || username==="" || password==="" || r_password==="") {
$('#error').text("You didn't fill everything");
}
else {
people[people.length] = new Person(username, email, password, r_password);
for(var key in people) {
//This should check weather this username was used before but I'm not really sure what to insert instead of "name"
if(people[people.length - 1].username === "name") {
$('#error').text("This username is already in use");
break;
}
else if(password !== r_password) {
$('#error').text("Passwords don't match");
break;
}
else {
document.cookie = email;
cookies[cookies.length] = document.cookie;
$('#error').text("Your registration is complete.");
break;
}
}
}
});
$('.btn').click(function() {
alert(cookies[cookies.length - 1]);
});
};
$(document).ready(main);

Creating a login in javascript - array comparison

I have a login box using a simple javascript login comparing usernames and passwords, before you all start I know about the security issues in using javascript for authentication. Here is the code
function validate() {
var un = document.getElementById("usern").value;
var pw = document.getElementById("pword").value;
var valid = false;
var unArray = ["markwalt", "jongossy", "lisacain", "jenndemp"];
var pwArray = ["mark1234", "flomaygo", "lisa1234", "jenny1234"];
var fnArray = ["Mark Walters", "Jonathan Goss", "Lisa Cain", "Jenny Dempsey"];
for (var i=0; i <unArray.length; i++) {
if ((un == unArray[i]) && (pw == pwArray[i])) {
valid = true;
break;
}
}
if (valid) {
alert ("Login was successful");
document.getElementById("mandatory1").value = un;
}
else {
alert("Invalid Username and/or Password! Please try again. You will not be able to submit this form without a successful login")
document.getElementById("pword").value = "";
document.getElementById("usern").value = "";
document.getElementById("usern").focus();
}
}
At the moment if the login is successful I'm posting the username to a hidden field which is then being used by a piece of a software. How do I associate the names in fnArray with the other correct username & password so that I can then grab associated full name and post that to the hidden field "mandator1" instead?

You can get the index of the correct user
var unArray = ["markwalt", "jongossy", "lisacain", "jenndemp"];
var pwArray = ["mark1234", "flomaygo", "lisa1234", "jenny1234"];
var fnArray = ["Mark Walters, Jonathan Goss, Lisa Cain, Jenny Dempsey"];
var index = 0;
for (var i=0; i <unArray.length; i++) {
if ((un == unArray[i]) && (pw == pwArray[i])) {
valid = true;
index = i;
break;
}
}
now you can access the correct data using
unArray[index];
// and so on for other arrays

Define a variable for full name, and set it if you have the valid user:
var fn = "";
/* ... */
valid = true;
fn = fnArray[i];
/* ... */
document.getElementById("mandatory1").value = fn;
Note: Actually you can check validity later on using fn. If it is empty string, then no user was logged in. This makes it have same purpose as valid, and more.

Try this.
function validate() {
var un = document.getElementById("usern").value;
var pw = document.getElementById("pword").value;
var valid = -1;
var unArray = ["markwalt", "jongossy", "lisacain", "jenndemp"];
var pwArray = ["mark1234", "flomaygo", "lisa1234", "jenny1234"];
var fnArray = ["Mark Walters","Jonathan Goss","Lisa Cain","Jenny Dempsey"];
for (var i=0; i <unArray.length; i++) {
if ((un == unArray[i]) && (pw == pwArray[i])) {
valid = i;
break;
}
}
if (valid != -1) {
alert ("Login was successful");
document.getElementById("mandatory1").value = fnArray[valid];
}
else {
alert("Invalid Username and/or Password! Please try again. You will not be able to submit this form without a successful login")
document.getElementById("pword").value = "";
document.getElementById("usern").value = "";
document.getElementById("usern").focus();
}
}

set mandatory1 when the login is successful based on i (in the for loop)
