declare username, email... etc outside the function.
then use: username = $('#signUp_username').val(); inside

I am working on a form but my form is not working whenever I press submit. I am trying to evaluate whether sections of the form is empty, the email, and the number of digits for a user id. When I press submit nothing happens and I have been stuck like this for a while. FYI I have to use plain js and html.

I think you should fix this line:
if checkEmail(email)
to
if (checkEmail(email))
you have forgotten the parentheses.
Edit:
I have completely fixed your code. Your errors:
you have forgotten to add else clauses for your field checkers, they were only returning false if the validation failed
your checking "if array contains value" was wrong, I have added a method from here
you were trying to focus on the values, not tags
you were trying to test email value from the "value of the value" not "value"
function validate() {
var studentid = document.getElementById("studentid").value;
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
if (nameEmpty(name)) {
if (studentidEmpty(studentid)) {
if (emailEmpty(email)) {
if (digitCheck(studentid)) {

Validate function always return false !! It shouldn't.
function validate(){
var studentid = document.getElementById("studentid").value;
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
return nameEmpty(name) && studentidEmpty(studentid) && emailEmpty(email) && digitCheck(studentid) && checkEmail(email) && verify(name, studentid);
}
Then be sure your form looks like :
<form name="form" onsubmit="return validate();" action="javascript:void(0)">
</form>
And your autofocus input to look like :
<input type="number" name="studentid" maxlength="8" id="studentid" required autofocus/>

You're forgetting the parentheses.
It is also wrong to start and end each function, try using the code below with these corrections.
function validate() {
var studentid = document.getElementById("studentid").value;
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
if (nameEmpty(name)) {
if (studentidEmpty(studentid)) {
if (emailEmpty(email)) {
if (digitCheck(studentid)) {
if (checkEmail(email)) {
verify(name, studentid)
}
}
}
}
}
return false;
}
function studentidEmpty(studentid) {
if (studentid == "") {
alert("Please provide your student id!");
studentid.focus();
return false;
}
}
function nameEmpty(name) {
if (name == "") {
alert("Please provide your name!");
name.focus();
return false;
}
}
function emailEmpty(email) {
if (email == "") {
alert("Please provide your email!");
email.focus();
return false;
}
}
function digitCheck(studentid) {
var ok = studentid.search(".{8,}");
if (ok != 0) {
alert("Please provide ID with 8 digits.");
return false;
}
}
function checkEmail(email) {
var filter = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (!filter.test(email.value)) {
alert('Please provide a valid email address');
email.focus;
return false;
}
}
function verify(name, studentid) {
var personList = [
["Joe", 11111111],
["Tammy", 22222222],
["Jones", 33333333]
];
for (list in personList) {
if (name in list && studentid in list) {
alert("Welcome! An email verification with be sent soon.");
return true;
} else {
alert("Student Name and/or ID not found in records");
return false;
}
}
}

I want to match both fields but every time i run this script so ans comes in false please check my code or logic

html part :
<input type="text" id="name" placeholder="Email" />
<input type="password" id="pass" placeholder="Password" />
<button type="submit" onclick="validateUser()">Submit</button>
<p id="para"></p>
JavaScript part :
var USERS = ['sumair', 'awais', 'umair'];
var PASSWORDS = [1234, 1234, 1234]
function validateUser() {
var username = document.getElementById('name').value;
var password = document.getElementById('pass').value;
for (var i in USERS) {
if (username == USERS[i] && password == PASSWORDS[i]) {
document.getElementById('para').innerHTML = "you are in";
} else {
document.getElementById('para').innerHTML = "you are not in";
}
}
}

You need to break loop when the condition is achieved.
//Create a variable
var result = false;
for (var i in USERS) {
if (username == USERS[i] && password == PASSWORDS[i]) {
result = true;
break;
}
}
//Based on the basis of result.
if (result) {
document.getElementById('para').innerHTML = "you are in";
} else {
document.getElementById('para').innerHTML = "you are not in";
}

for (var i in USERS) {
if (username == USERS[i] && password == PASSWORDS[i]) {
document.getElementById('para').innerHTML = "you are in";
break;
} else {
document.getElementById('para').innerHTML = "you are not in";
}
}

Request to server fails in Firefox when type=submit for button

My html code sends the request to php to send email. In my case the email can be sent in Google Chrome & Edge but not in Firefox when I set the button type=submit, when I change type=button, it works fine. My javascript code is:
function Send() {
var allset = true;
var namevalid = true;
var emailvalid = false;
var commentvalid = false;
var sent = 0;
var emailPattern = /^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
if ($("#email").val() == '' || $("#email").val() == null) {
$("#email").addClass("invalid");
allset = false;
}
else {
if (!$("#email").val().match(emailPattern)) {
$("#email").removeClass("valid");
$("#email").addClass("invalid");
allset = false;
}
else {
emailvalid = true;
$("#email").addClass("valid");
}
}
if ($("#comment").val() == '' || $("#comment").val() == null) {
$("#comment").addClass("invalid");
allset = false;
}
else {
commentvalid = true;
$("#comment").addClass("valid");
}
$("#name").addClass("valid");
if (namevalid === true && emailvalid === true && commentvalid === true) {
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
var number = document.getElementById("number").value;
var demo = document.getElementById("sel1").value;
var comment = document.getElementById("comment").value;
alert("Request Successfully Received");
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function () {
if (xhttp.readyState == 4 && xhttp.status == 200) {
alert(xhttp.responseText)
}
};
sent = 1;
xhttp.open("POST", "email.php?" + "name=" + name + "&mail=" + email + "&phone=" + number + "&msg=" + comment + "&demo=" + demo, true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send();
}
else
{
alert("Please fill all the fields correctly");
}
}
My html for form's button is:
<form class="form" id="form1">
<p class="name">
<input name="name" type="text" class="validate[required,custom[onlyLetter],length[0,100]] feedback-input" placeholder="Name" id="name" />
</p>
<p class="email">
<input name="email" type="text" class="validate[required,custom[email]] feedback-input" id="email" placeholder="Email" />
</p>
<p class="number">
<input type="text" name="telephone" maxlength="30" class="feedback-input" size="30" id="number" placeholder="Number">
</p>
<p class="number" id="demotype">
<select class="form-control feedback-input demotype" id="sel1" name="demo">
<option> something </option>
</select>
</p>
<p class="text">
<textarea name="text" class="validate[required,length[6,300]] feedback-input" id="comment" placeholder="Comment"></textarea>
</p>
<div class="submit">
<input type="submit" id="button-blue" onclick="Send()" value="Send" />
<div class="ease"></div>
</div>
</form>

'type=submit' is basically for submitting forms and 'type=button' is just a button to be bind with some functions. If you don't have any form as its parent element and an error occurs when you click the button, I suggest you to use 'type=button' instead.

Just add return false; at the end of function becuase submit button submits your form. Like this.
function Send() {
var allset = true;
var namevalid = true;
var emailvalid = false;
var commentvalid = false;
var sent=0;
var emailPattern = /^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
if ($("#email").val() == '' || $("#email").val() == null) {
$("#email").addClass("invalid");
allset = false;
}
else {
if (!$("#email").val().match(emailPattern)) {
$("#email").removeClass("valid");
$("#email").addClass("invalid");
allset = false;
}
else {
emailvalid = true;
$("#email").addClass("valid");
}
}
if ($("#comment").val() == '' || $("#comment").val() == null) {
$("#comment").addClass("invalid");
allset = false;
}
else {
commentvalid = true;
$("#comment").addClass("valid");
}
$("#name").addClass("valid");
if (namevalid === true && emailvalid === true && commentvalid === true) {
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
var number = document.getElementById("number").value;
var demo=document.getElementById("sel1").value;
var comment = document.getElementById("comment").value;
alert("Request Successfully Received");
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
alert(xhttp.responseText)
}
};
sent=1;
xhttp.open("POST", "email.php?"+"name="+name+"&mail="+email+"&phone="+number+"&msg="+comment+"&demo="+demo, true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send();
}
else
{
alert("Please fill all the fields correctly");
}
return false;
}

resetMsg();
var val = true;
//Username Validation
if (isEmpty(log_in.username.value)) {
document.getElementById("usernamemsg").innerHTML = " Empty";
val = false;
}
//Password Validation
if (isEmpty(log_in.password.value)) {
document.getElementById("passwordmsg").innerHTML = " Empty";
val = false;
}
return val;
}
</script>
The validations won't work and I dont know why. This is a school project.
my main problem is that the script isnt running when im submiting the form ,when there even some errors at the form(what the user submits) it still goes to the next page and no innerHtml massage is shown.

Here, I went through your code, refractored a lot of it, wrote out some comments on how to improve it.
What stops the form from submitting is returning false. You're returning a variable called val, and if there is an error that variable is set to false, thus returning false and preventing the form from submitting.
I recommend taking the JS and putting it in your text editor and reading through everything. You should learn a good bit.

I just did first name cause I have to work now, but you should be able to work off of this.
function validateForm(){
resetMsg();
var val = true;
if(isEmpty(firstName.value)){
firstNameMsg = 'Empty';
val = false;
}else if(isNumeric(firstName.value)){
firstNameMsg = 'Letters Only';
val = false;
}else if(isShort(firstName.value)){
firstNameMsg = 'Too Short';
val = false;
}
return val;
}
