If the form is refreshing the page, you'll need to use preventDefault to cancel its default behaviour then use reset() to reset the form.
const form = document.querySelector('form');
form.addEventListener('submit', e => {
e.preventDefault();
[...form.elements].forEach(input => console.log(`${input.name}: ${input.value}`)); // Not Important
form.reset();
});
<form method="POST">
<input type="text" name="name" placeholder="name">
<input type="password" name="password" placeholder="password">
<button type="submit">Submit</button>
</form>

In JavaScript there is a function for forms which will reset the form clearing all the data in it, ready for another submit. This can be accomplished by running a JavaScript function on submit. This requires a couple changes in your code.
Firstly, we need to change this:
<button type="submit" class="btn btn-success w-100 submit">Send Message</button>
to this:
<button type="button" onclick="submitForm1()" class="btn btn-success w-100 submit">Send Message</button>
Once done, we can add some JavaScript to your page. If you have a JavaScript file linked to the page already, you can just add this code to that.
function submitForm1() {
let form = document.getElementsByClassName("gform");
form.submit();
form.reset();
}
You can also use document.getElementById("[id]"); and add an ID to your form. This is also preferable.

The first thing that comes to mind it's do all this on js so you can through ajax request send what you want. But I think it's not what you're looking for. You can't send data from page without refreshing, that's how it's work, php or html with some functional. You can change ...
<button type="button" class="btn btn-success w-100">Send Message</button>
... and collect all data by JavaScript and send it through ajax.

Why is my form not returning an alert when password does not match the confirm password field Javascript?

So I'm new to JS, and I'm trying to make this form prevent submission if password does not match the confirm password field. However, when I enter in 2 different passwords, I don't get an alert like I've coded in the script below. Any thoughts? For reference, the form was built w/ bootstrap.
<form class="form-signin">
<div class="form-label-group">
<input type="text" id="fullName" class="form-control" placeholder="Username" required autofocus>
<label for="fullName">Full name</label>
</div>
<div class="form-label-group">
<input type="email" id="inputEmail" class="form-control" placeholder="Email address" required>
<label for="inputEmail">Work email</label>
</div>
<div class="form-label-group">
<input type="password" id="inputPassword" class="form-control" placeholder="Password" required>
<label for="inputPassword">Password</label>
</div>
<div class="form-label-group">
<input type="password" id="inputConfirmPassword" class="form-control" placeholder="Password" required>
<label for="inputConfirmPassword">Confirm password</label>
</div>
<button class="btn btn-lg btn-primary btn-block text-uppercase" id ="register-btn" type="submit">Register</button>
<hr class="my-4">
<div class="registration-login">
<p class="already-have__account">Already have an account?</p> Login
</p>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
<div class="registration__section">
<h2>Innovative supply chain teams use Rumi to manage scalable and sustainable packaging.

<script>
var form = document.getElementById('form-signin');
form.onsubmit = function() {
if (inputPassword.value !== inputConfirmPassword.value) {
alert("Your passwords don't match");
return false;
}
else {
return true;
}
}

Just a minor mistake.
You are using get getElementById.
var form = document.getElementById('form-signin');
There is no id with 'form-signin',
<form class="form-signin">
Rename the class to id.
<form id="form-signin">
Check out this (JSFiddle). It's working here.

Create form action to js page

I want to create login form, and then the result is going to another page, using js to catch the value and create the process.
I have success created it using onclick, but I want to change onclick to onsubmit as I don't want to click the button, just press 'Enter' keyboard, the process is working. I have tried change from onclick to onsubmit process, but I still not get the value on the js page.
Here's the login form
<form >
<div class="input-group form-group">
<div class="input-group-prepend">
<span class="input-group-text"><i class="fas fa-user"></i></span>
</div>
<input type="text" class="form-control" placeholder="Phone Number" name="phone_number" id="phone_number">
</div>
<div class="input-group form-group">
<div class="input-group-prepend">
<span class="input-group-text"><i class="fas fa-key"></i></span>
</div>
<input type="password" class="form-control" placeholder="Password" name="password" id="password">
</div>
<div class="form-group">
<input type="button" value="Login" class="btn float-justify login_btn" onClick="login()">
</div>
</form>
<script src="<?= base_url() ?>assets/js-process/login/login.js" type="text/javascript"></script>
Here's the js page
function login()
{
var phone_number = $('#phone_number').val();
var password = $('#password').val();
console.log(phone_number)
}
I have changed the onclick to onsubmit, but I can't get the value on the js page again.
here's my change
<form id="myform" onsubmit="login()">
......
<div class="form-group">
<input type="submit" value="Submit" class="btn float-justify login_btn">
</div>
Do you know where's the error on my code ?
Thank you

As I see it , everything is good , where should be looking now on 2 things
first its jquery you are using but i can not see its link
second check your base url , it is properly being generated or not
Below you can see its working on onclick
same way you can do with on submit but you have to pass event in function so that you can stop its default action . you can do that using event.preventDefault();
function login(e)
{
e.preventDefault();
var phone_number = $('#phone_number').val();
var password = $('#password').val();
alert(phone_number)
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form onSubmit="login(event)">
<div class="input-group form-group">
<div class="input-group-prepend">
<span class="input-group-text"><i class="fas fa-user"></i></span>
</div>
<input type="text" class="form-control" placeholder="Phone Number" name="phone_number" id="phone_number">
</div>
<div class="input-group form-group">
<div class="input-group-prepend">
<span class="input-group-text"><i class="fas fa-key"></i></span>
</div>
<input type="password" class="form-control" placeholder="Password" name="password" id="password">
</div>
<div class="form-group">
<input type="submit" value="Login" class="btn float-justify login_btn" >
</div>
</form>

to redirect the same page after form submit

I have a form in my webpage Index.html. When I submit my form it redirects to the action page.
I want the page to redirect to itself (index.html) after completing the action.
<div class="container">
<div class="row marginbot-80">
<div class="col-md-8 col-md-offset-2">
<form id="contact-form" method="post" action="mailfunc.php" class="wow bounceInUp" data-wow-offset="10" data-wow-delay="0.2s">
<div class="row marginbot-20">
<div class="col-md-6 xs-marginbot-20">
<input type="text" class="form-control input-lg" id="name" placeholder="Enter name" required="required" />
</div>
<div class="col-md-6">
<input type="email" class="form-control input-lg" id="email" placeholder="Enter email" required="required" />
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control input-lg" id="subject" placeholder="Subject" required="required" />
</div>
<div class="form-group">
<textarea name="message" id="message" class="form-control" rows="4" cols="25" required="required" placeholder="Message"></textarea>
</div>
<button "style=width:40 height:40" class="btn btn-skin" type="submit" id="btnContactUs">Send Message</button>
</div>
</div>
</form>
</div>
</div>
</div>

You could redirect after the script in mailfunc.php to your index.html like this:
header("Location: index.html");
exit();

Currently your submit will open a POST request to mailfunc.php where your form data (most probably) will be processed.
You can quite easily forward from mailfunc.php to index.html using some Javascript code like:
window.location.href = 'index.html';

Try this.
$referer = $_SERVER['HTTP_REFERER'];
header("Location: $referer");
This helps you to redirect to the same page where you are submitting the form
