Linking two pages - javascript

I am working on trying to link pages together so if a person were to login using the login page, they would be redirected to a specific created page, and if a user clicked the register button, they would be redirected to the register page and from there, after inputting in information, they would be directed to another page. The button for login or register does not work. Is there a way to fix this?
So far I have this for my login page.
function login() {
var users = ["admin1", "admin2", "admin3", "admin4"];
var pass = ["pass1", "pass2", "pass3", "pass4"];
ivar aUser = document.getElementById("user_name").value;
var aPass = document.getElementById("password").value;
for (i = 0; i < users.length; i++) {
if (users[i] == aUser && pass[i] == aPass) {
window.location = "dashboard.php";
break;
}
}
var myOut = document.getElementById("output");
myOut.innerHTML = "Who Are You? / Incorrect Password";
myOut.className = "error";
function init() {
var login_button = document.getElementById("login_button");
if (login_button !== null) {
login_button.onclick = login;
}
var register_button = document.getElementById("register_button");
if (register_button !== null) {
register_button.onclick = validation;
}
for (i = 1; i <= 10; i++) {
var myErr = document.getElementById("err" + i);
if (myErr !== null) {
myErr.className = "error";
}
}
}

Several errors

You can make the test simpler:
var userPos = users.indexOf(aUser);
if (userPos !=-1 && userPos === pass.indexOf(aPass)) {
...

name and comment are inputs.
I type some text but append doesn't working and the new text that entered replace the first one.

Am not sure why your looping the name property, but here is a working example!

SubmitComment($('.name'), $('.comment'));
}
function SubmitComment(name, comment) {
let newComment = censor(comment)
let demo = $("#demo");
demo.html("")

Regular Expression always false

So I am writing some javascript to check if a user inputs a gmail address.
At the moment I have the code thats below, but no matter what I do it is giving me false. even when the input has #gmail.com...I feel that the mistake is how I am grabbing the user input in a variable and then testing it with test().
Javascript:
<script>
function validationCheck() {
var email = document.getElementById("inputEmail");
var gmailPatt = /#gmail.com/i;
var emailMatch = gmailPatt.test(email);
if (emailMatch == false || emailMatch == true) {
document.getElementById("emailError").innerHTML =
"<p>" + emailMatch + "</p>";
} else {
}
}
</script>
html
<form>
<div class="form-group row">
<div>
<label for="inputEmail" class="col-sm-1">Email:</label>
<input
type="text"
class="form-control col-sm-1"
id="inputEmail"
placeholder="username#gmail.com"
/>
<p id="emailError"></p>
</div>
</div>
<button type="button" onclick="validationCheck()">Check</button>
</form>

You need to check the value of the input, var emailMatch = gmailPatt.test(email.value);
function validationCheck() {
var email = document.getElementById("inputEmail");
var gmailPatt = /#gmail.com/i;
var emailMatch = gmailPatt.test(email.value);
if (emailMatch == false || emailMatch == true) {
document.getElementById("emailError").innerHTML =
"<p>" + emailMatch + "</p>";
} else {}
}
<form>
<div class="form-group row">
<div>
<label for="inputEmail" class="col-sm-1">Email:</label>
<input type="text" class="form-control col-sm-1" id="inputEmail" placeholder="username#gmail.com" />
<p id="emailError"></p>
</div>
</div>
<button type="button" onclick="validationCheck()">Check</button>
</form>

Trying to store a completed form into an array

I'm creating a registration page and am currently attempting to store the inputs of the form into an array. I'm using
var form_inputs = document.getElementsByClassName("form_input");
to store the inputs in the same place, however if I try to alert form_inputs to test if anything is actually being stored, it just alerts "Undefined".
function validate_form(event) {
var forename = document.getElementById("forename");
var surname = document.getElementById("surname");
var username = document.getElementById("username");
var password = document.getElementById("password");
var re_password = document.getElementById("re_password");
var email = document.getElementById("email");
var errors = 0
var special_chars = "<>#!#$%^&*()_+[]{}?:;|'\"\\,./~`-=";
var form_inputs = document.getElementsByClassName("form_input");
if (forename.value == "") {
//document.getElementById("forename").style.background = "red";
forename_confirmation.style.visibility = 'visible';
var errors = errors + 1
} else
for (var i = 0; i < forename.value.length; i++) {
if (special_chars.indexOf(forename.value.charAt(i)) != -1) {
forename_chars.style.visibility = 'visible'
}
}
if (surname.value == "") {
//document.getElementById("surname").style.background = "red";
surname_confirmation.style.visibility = 'visible';
var errors = errors + 1
} else
for (var i = 0; i < surname.value.length; i++) {
if (special_chars.indexOf(surname.value.charAt(i)) != -1) {
surname_chars.style.visibility = 'visible'
}
}
if (username.value == "") {
//document.getElementById("username").style.background = "red";
username_confirmation.style.visibility = 'visible';
var errors = errors + 1
} else
for (var i = 0; i < username.value.length; i++) {
if (special_chars.indexOf(username.value.charAt(i)) != -1) {
username_chars.style.visibility = 'visible'
}
}
if (password.value == "") {
//document.getElementById("password").style.background = "red";
pass_confirmation.style.visibility = 'visible';
var errors = errors + 1
}
if (password.value != re_password.value) {
//document.getElementById("re_password").style.background = "red";
repass_confirmation.style.visibility = 'visible';
var errors = errors + 1
}
if (email.value == "") {
//document.getElementById("email").style.background = "red";
var errors = errors + 1
}
if (errors != "0") {
alert("Whoops! Looks like you didn't enter your details properly");
console.log(form_inputs);
event.preventDefault(); // Prevent the form from submitting
}
if (!email.value.includes("#") || !email.value.includes(".")) {
//document.getElementById("email").style.background = "blue";

Form Validation using JavaScript?

I'm trying to use form validation using JavaScript, however I don't seem to get any response, not even an alert even though it's there.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Example Form</title>
<script type="text/javascript">
function CheckForBlank() {
if(document.getElementById('name').value="") {
alert("enter something valid");
return false;
}
}
</script>
</head>
<body>
<form method="post" action="2013.php" onsubmit="return CheckForBlank();">
Name: <input type="text" name="name" id="name"/>
Age: <input type="text" name="age" id="age"/>
Email: <input type="text" name="email" id="email"/>
<p><input type="submit" value="Submit" /></p>
</form>
</body>
</html>

use === or == for condition checking in javascript.
if(document.getElementById('name').value === ""){
alert("enter something valid");
return false;
}

You have to use == for comparison.= is used for assigment
if(document.getElementById('name').value == ""){
alert("enter something valid");
return false;
}

Working Demo
Here Your issue is regarding if condition only! You must use == OR === in JavaScript for comparison.
Below is corrected script!
function CheckForBlank() {
if(document.getElementById('name').value=="") {
alert("enter something valid");
return false;
}
}
If you remove Or avoid return false, form will postback Even if Validation fails! So, return false means, exiting from function after if is must, and which is missed out in another answer!!

You are using = that is assignment operator, use == comparison operator that's work fine
<head>
<title>Example Form</title>
<script type="text/javascript">
function CheckForBlank() {
if(document.getElementById('name').value=="") {
alert("enter something valid");
return false;
}
}
</script>
</head>
<body>
<form method="post" onsubmit="return CheckForBlank();">
Name: <input type="text" name="name" id="name"/>
Age: <input type="text" name="age" id="age"/>
Email: <input type="text" name="email" id="email"/>
<p><input type="submit" value="Submit" /></p>
</form>
</body>

I can't believe I've never realised this until now, although if you attach your Javascript to the form submission event, instead of the button submit event; the normal browser verification works (ie. input[type="email], required="required", etc.).
Works in Firefox & Chrome.
// jQuery example attaching to a form with the ID form
$(document).on("submit", "#form", function(e) {
e.preventDefault();
console.log ("Submitted! Now serialise your form and AJAX submit here...");
})

I have done a better way to do form validation using bootstrap. You can take a look at my codepen http://codepen.io/abhilashn/pen/bgpGRw

for(var i = 0; i < inputElems.length; i++) {
com_abhi.EVENTS.addEventHandler(inputElems[i], 'focus', highlightFormElement, false);
com_abhi.EVENTS.addEventHandler(inputElems[i], 'blur', unHightlightFormElement, false);
}
/* Add the code for the input elements */
inputElems = document.getElementsByTagName('input');
for(var i = 0; i < inputElems.length; i++) {
if(sValidElems.indexOf(inputElems[i].getAttribute('type') != -1)) {
com_abhi.EVENTS.addEventHandler(inputElems[i], 'focus', highlightFormElement, false);
com_abhi.EVENTS.addEventHandler(inputElems[i], 'blur', unHightlightFormElement, false);
}
}
/* submit handler */
com_abhi.EVENTS.addEventHandler(document.getElementById('form1'), 'submit' , validateAllfields, false);
/* Add the default focus handler */
document.getElementsByTagName('input')[0].focus();
/* Add the event handlers for validation */
