Send data using Javascript without having to refresh the page

As I work on submitting a form in JavaScript, the AJAX feature is functioning perfectly when manually submitting the form. However, there seems to be an issue when JavaScript attempts to submit it, resulting in a refresh.

The current code snippet I am working with looks like this:

:javascript
  wistiaEmbed = Wistia.embed("#{@chapter.video_id}", {
    autoPlay: true,
    videoFoam: true,
    playerColor: 'E68482'
  });
  wistiaEmbed.bind("end", function () {
    document.getElementById('target').style.display = 'none';
    document.getElementById('finished').style.display = 'block';
    document.getElementById('new_chapter_completion').submit();
  });

In addition, here is a preview of my form structure:

= form_for current_user.chapter_completions.build, remote: true, authenticity_token: true do |f|
 = hidden_field_tag :chapter_id, @chapter.id
 = f.submit

I have identified that the main problem lies within the .submit(); method being used. Can anyone guide me on what alternative approach I should consider?

Moreover, I am interested in having the form data submitted by JavaScript without the need for the form to be visibly present. Is there a way to achieve this while still maintaining the required #id?

Your response was:

The form works perfectly when manually submitted

I assume manual submission means clicking on the submit button, correct?

If that's the case, why not try this solution?

In HTML:

<form id="new_chapter_completion">
<!-- input fields go here -->
<input type="submit" value="Submit" id="submit-btn">
</form>

In JS (using JQuery, although it can be done without it):

$(document).ready(function() {
    // your code here, but instead of
    // document.getElementById('new_chapter_completion').submit();
    // you would do this:
    $('#submit-btn').trigger('click'); // simulating a real click
});

Additionally, I prefer for the form to be discreetly hidden

Hiding elements usually involves CSS techniques. There are various methods. For instance, you can make the main wrapper DIV of your page (CSS):

position:relative;
z-index:10;

and place your form within this wrapper (#new_chapter_completion):

position:absolute;
left:0;
top:0;
z-index:1;
