Answer 1

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>

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.

Answer 3

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.
