I am creating a multiple section form that needs to validate each section before proceeding to show the next. When I hit continue I want to run a validation that triggers a response on the section above but not the whole form. In addition I want this in one form so that it can be uploaded into IBM forms. I know jQuery is powerful but I don't understand if you can have it all contained in the html.
<script language="JavaScript">
var currentLayer = 'page1';
function showLayer(lyr) {
hideLayer(currentLayer);
document.getElementById(lyr)
.style.visibility = 'visible';
currentLayer = lyr;
}
function hideLayer(lyr) {
document.getElementById(lyr).
style.visibility = 'hidden';
}
function showValues(form) {
var values = '';
var len = form.length - 1;
//Leave off Submit Button
for(i=0; i<len; i++) {
if (form[i].id.indexOf("C") != -1 || // if statement over this one validating visible form elements before continuing
form[i].id.indexOf("B") != -1)
//Skip Continue and Back Buttons
continue;
values += form[i].id;
values += ': ';
values += form[i].value;
values += '\n';
}
alert(values);
}
</script>
</head>
<body>
<div class="container">
<form action="javascript:void(0)" onSubmit="showValues (this)" method="post" enctype="text/plain">
<div id="page1" class="page" style="visibility:visible;">

I'm working on a password matching validator and am stuck. It seems like the code is structured correctly but it reads the passwords as matching no matter what. Also would like to know what I'm doing wrong in regards to getting the event to keep validating without reloading the page, I was hoping event++ would get the job done.
Here is the Javascript
<script>
const pass1 = document.getElementById("password1");
const pass2 = document.getElementById("password2");
const p = document.getElementById("confirm")
function passCheck () {
if (pass1 !== pass2) {
return p.innerHTML= "Passwords do not match";
}
else {
return p.innerHTML="Passwords match";
}
}
pass2.addEventListener("keyup", function() {
event++;
passCheck(pass1, pass2);})
</script>
Here is the HTML
<body>
<div class="rSide">
<div class="formBox">
<form action="#" method="post">
<div class="formLabel">
<label for="FName">First name</label>
<input type="text" id="FName" name="FName" placeholder="Your First Name" required>
</div>
<div class="formLabel">
<label for="LName">Last Name</label>
<input type="text" id="LName" name="LName" placeholder="Your Last Name" required>
</div>
<div class="formLabel">
<label for="email">Email</label>
<input type="email" id="email" name="email" placeholder="Your Email" required>
</div>
<div class="formLabel">
<label for="phone">Phone Number</label>
<input type="number" id="phone" name="phone" placeholder="Your Phone Number" required>
</div>
<div class="formLabel">
<label for="password1">Password</label>
<input type="text" id="password1" name="password1" required>
</div>
<div class="formLabel">
<label for="password2">Confirm Password</label>
<input type="text" id="password2" name="password2" required>
<p id="confirm"></p>
</div>
<button type="submit" class="account">Create Account</button><br>
</form>
</div>
<p>Already have an account? <a>Log in</a></p>
</div>
</div>
</body>
You're getting the elements:
const pass1 = document.getElementById("password1");
What you want are the values:
const pass1 = document.getElementById("password1").value;
Alternatively, if you need to reference the elements otherwise (such as when calling pass2.addEventListener), you can reference the values just during the comparison:
if (pass1.value !== pass2.value) {
However you want to structure the code is up to you. The main point to remember is when you're referencing the entire HTML element and when you just want the .value from that element (specifically for <input> elements).
As an aside, you're pass arguments to a function that doesn't expect any:
passCheck(pass1, pass2);
Either add the parameters to the function itself, or continue using the globally scoped variables within the function and don't pass anything to it:
passCheck();
I have the following contact form:
<form id="post">
<label for="name">Name</label>
<input id="name" name="name" type="text">
<label for="surname">Surname</label>
<input id="surname" name="surname" type="text">
<label for="email">E-mail</label>
<input id="email" name="email" type="text">
<label for="subject">Object</label>
<input id="subject" name="subject" type="text">
<label for="text">Text</label>
<textarea id="text" name="text"></textarea>
<button type="submit" disabled>Submit</button>
<!-- Honeypot -->
<div style="position:absolute;left:-5000px" aria-hidden="true">
<input type="text" name="ijdssliouhois8ds8989sd" tabindex="-1" value="">
</div>
<!-- /Honeypot -->
</form>
In order to disable submit button until all input/textarea fields are filled, I'm using the following code:
post.oninput = function() {
var empty = false;
for (var i = 0; i < 5; i++) {
if (post[i].value.trim() === "") {
empty = true;
}
}
if (empty) {
post[5].disabled = true;
} else {
post[5].disabled = false;
}
};
It works perfectly.
post.oninput = function() {
var empty = false;
for (var i = 0; i < 5; i++) {
if (post[i].value.trim() === "") {
empty = true;
}
}
if (empty) {
post[5].disabled = true;
} else {
post[5].disabled = false;
}
};
<form id="post">
<label for="name">Name</label>
<input id="name" name="name" type="text">
<label for="surname">Surname</label>
<input id="surname" name="surname" type="text">
<label for="email">E-mail</label>
<input id="email" name="email" type="text">
<label for="subject">Object</label>
<input id="subject" name="subject" type="text">
<label for="text">Text</label>
<textarea id="text" name="text"></textarea>
<button type="submit" disabled>Submit</button>
<!-- Honeypot -->
<div style="position:absolute;left:-5000px" aria-hidden="true">
<input type="text" name="ijdssliouhois8ds8989sd" tabindex="-1" value="">
</div>
<!-- /Honeypot -->
</form>
But I would like to achieve the same result using methods such .filter, .find, .map or .some - if possible (the best one in terms of performance).
Would you give me some suggestions?
Use the :scope > [name] query string to select children of the form which are input-like, and if .some of them aren't filled, disable the button:
const post = document.querySelector('form');
post.oninput = function() {
post.querySelector('button').disabled = [...post.querySelectorAll(':scope > [name]')]
.some(input => !input.value.trim())
};
<form id="post">
<label for="name">Name</label>
<input id="name" name="name" type="text">
<label for="surname">Surname</label>
<input id="surname" name="surname" type="text">
<label for="email">E-mail</label>
<input id="email" name="email" type="text">
<label for="subject">Object</label>
<input id="subject" name="subject" type="text">
<label for="text">Text</label>
<textarea id="text" name="text"></textarea>
<button type="submit" disabled>Submit</button>
<!-- Honeypot -->
<div style="position:absolute;left:-5000px" aria-hidden="true">
<input type="text" name="ijdssliouhois8ds8989sd" tabindex="-1" value="">
</div>
<!-- /Honeypot -->
</form>
You could also use the required attribute, if it'll suit your needs, though the button won't appear disabled - rather, it'll redirect the user to the next required field:
<form id="post">
<label for="name">Name</label>
<input required id="name" name="name" type="text">
<label for="surname">Surname</label>
<input required id="surname" name="surname" type="text">
<label for="email">E-mail</label>
<input required id="email" name="email" type="text">
<label for="subject">Object</label>
<input required id="subject" name="subject" type="text">
<label for="text">Text</label>
<textarea required id="text" name="text"></textarea>
<button type="submit">Submit</button>
<!-- Honeypot -->
<div style="position:absolute;left:-5000px" aria-hidden="true">
<input type="text" name="ijdssliouhois8ds8989sd" tabindex="-1" value="">
</div>
<!-- /Honeypot -->
</form>
I have created a form that is submitting the form in its entirety and preventing the page from reloading locally.
As soon as it is posted to the website and we try and plug in the handler (SalesForce). The form still submits but the page reloads and we cant have that. As there is data that reveals once the "submit" button is clicked. The button is controlling multiple JS and functions.
Can anyone look at the code and see where the problem lies?

Like I said, you can use Ajax to achieve what you want.
Here are a few links that will help you in that direction

I am trying to make a sign up form with javascript validation but the error message only flashes for a second.
I tried searching other similar questions but I couldn't find the answer...
This is my form code
<form method="post" name="signupForm">
<div id="signup-form" class="col-md-12 col-sm-12 col-xs-12">
<span id="error"></span>
<div class="form-group" id="inputFirst">
<label for="firstname">First Name:</label>
<input class="form-control" type="text" name="first_name" id="firstname" placeholder="John" value="">
</div>
<div class="form-group" id="inputLast">
<label for="lastname">Last Name:</label>
<input class="form-control" type="text" name="last_name" id="lastname" placeholder="Doe" value="">
</div>
<div class="form-group" id="inputEmail">
<label for="signup_email">Email Address:</label>
<input class="form-control" type="email" id="signup_email" name="email" placeholder="example#gmail.com" value="">
</div>
<div class="form-group" id="inputPassword">
<label for="user_password">Password:</label>
<input class="form-control" type="password" id="user_password" name="password" placeholder="Create a Password">
</div>
<button type="submit" onclick="validateForm()" class="btn button">Sign Up</button>
</div>
</form>
And this is my Validation Function
function validateForm() {
var first= document.forms["signupForm"]["firstname"].value;
var last = document.forms["signupForm"]["lastname"].value;
var email= document.forms["signupForm"]["email"].value;
var pass = document.forms["signupForm"]["password"].value;
var msg = "";
var valid= true;
checkname = /[A-z]/;
checkemail= /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/;
if(!/\w/.test(pass))
{
msg="Password can only contain [a-z, A-Z, 0-9, _ (underscore)]";
valid= false;
}
if(!checkemail.test(email))
{
msg="Email address Invalid";
valid= false;
}
if(!checkname.test(first))
{
msg="First and Last Name can only contain alphabets";
valid= false;
}
if(first==="" && last==="" && email==="" && pass==="")
{
msg="Please fill every field given below";
valid= false;
}
document.getElementById("error").innerHTML = msg;
return valid;
}
You should use return validateForm(), this way when the validateForm will return false - it will stop the form from submitting.
function validateForm() {
var first= document.forms["signupForm"]["firstname"].value;
var last = document.forms["signupForm"]["lastname"].value;
var email= document.forms["signupForm"]["email"].value;
var pass = document.forms["signupForm"]["password"].value;
var msg = "";
var valid= true;
debugger;
checkname = /[A-z]/;
checkemail= /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/;
if(!/\w/.test(pass))
{
msg="Password can only contain [a-z, A-Z, 0-9, _ (underscore)]";
valid= false;
}
if(!checkemail.test(email))
{
msg="Email address Invalid";
valid= false;
}
if(!checkname.test(first))
{
msg="First and Last Name can only contain alphabets";
valid= false;
}
if(first==="" && last==="" && email==="" && pass==="")
{
msg="Please fill every field given below";
valid= false;
}
document.getElementById("error").innerHTML = msg;
return valid;
}
<form method="post" name="signupForm">
<div id="signup-form" class="col-md-12 col-sm-12 col-xs-12">
<span id="error"></span>
<div class="form-group" id="inputFirst">

Your form is probably still be submitting as you are not stopping the form submission. Your event handler is "onClick" on the submit button. This not necessarily stop the form.
You only see the error message for a split second because the page does a full page reload.
Your validation function should be bound to the "onSubmit" event instead.
<form onsubmit="return validateForm();">
I am having trouble pinpointing why my javascript code is failing to validate the form on the bottom. Any help is appreciated. I'm new and learning when in comes to javascript.
Here's the javascript:
<script type="text/javascript" language="javascript">
function validate(){
//Initialize array
var field = new Array;
var field = [document.getElementById('first_name'),document.getElementById('last_name'),document.getElementById('address'),document.getElementById('eadress'),document.getElementById('city'),document.getElementById('state'),document.getElementById('telephone'),document.getElementById('comments')];
//Error tracker
var error = 0;
//Validation Loop
for (i=0;i<field.length;i++)
{
if (field[i].value == "")
{
error++;
}
}
//If no errors are present, submit
if (error == 0)
{
document.contact-form.submit();
}
//Else, display alert
else {
alert("One or more fields are empty.");
return false;
}
}
Here's the form:
<div id="registration">
<form action="" method="post" onsubmit="return validate();" id="contact-form">

I just corrected your code. it seems that in the array you are asking for eadress and the field is eaddress with 2 d's
In the script, you misspelt eaddress as eadress :)
You misspelled one of the fields ids in your array definition document.getElementById('eadress') is eaddress in HTML id attribute
