Vanilla JS Solution

The HTML would remain the same, but you wouldn't need to load jQuery

<script type="text/javascript">
    window.onload = () => {
      const myModal = new bootstrap.Modal('#onload');
      myModal.show();
    }
</script>

Additionally, you may give a description of your modal dialog with aria-describedby on .modal. Note that you don’t need to add role="dialog" since we already add it via JavaScript. Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more.

Just wrap the modal you want to call on page load inside a jQuery load event on the head section of your document and it should popup, like so:

<script type="text/javascript">
    $(window).on('load', function() {
        $('#myModal').modal('show');
    });
</script>

HTML

<div class="modal hide fade" id="myModal">
    <div class="modal-header">
        <a class="close" data-dismiss="modal">×</a>
        <h3>Modal header</h3>
    </div>
    <div class="modal-body">
        <p>One fine body…</p>
    </div>
    <div class="modal-footer">
        <a href="#" class="btn">Close</a>
        <a href="#" class="btn btn-primary">Save changes</a>
    </div>
</div>

You can still call the modal within your page with by calling it with a link like so:

<a class="btn" data-toggle="modal" href="#myModal">Launch Modal</a>

You don't need javascript to show modal

The simplest way is replace "hide" by "in"

class="modal fade hide"

class="modal fade in"

and you need add onclick = "$('.modal').hide()" on button close;

PS: I think the best way is add jQuery script:

$('.modal').modal('show');

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the to override default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal. [source]

var myModal = new bootstrap.Modal(document.getElementById('myModal'), options)

var myModal = new bootstrap.Modal(document.getElementById("exampleModal"), {});
document.onreadystatechange = function () {
  myModal.show();

As for your code, you didn't follow the right way to show/toggle a modal in Vanilla JavaScript. Why did you expect myModal.show() to happen while myModal is just a DOM element?

var myModal = new bootstrap.Modal(document.getElementById('exampleModal'))
myModal.show()
