I don't know JavaScript at all. The Bootstrap documentation says to
Call the modal via JavaScript:
$('#myModal').modal(options)
I have no clue how to call this on a page load. Using the supplied code on the Bootstrap page I can successfully call the Modal on an element click, but I want it to load immediately on a page load.

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:
JS
<script type="text/javascript">
$(window).on('load', function() {
$('#myModal').modal('show');
});
</script>
HTML
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<a href="#" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
You can still call the modal within your page with by calling it with a link like so:
<a class="btn" data-toggle="modal" href="#myModal">Launch Modal</a>
You don't need javascript to show modal
The simplest way is replace "hide" by "in"
class="modal fade hide"
so
class="modal fade in"
and you need add onclick = "$('.modal').hide()" on button close;
PS: I think the best way is add jQuery script:
$('.modal').modal('show');
Just add the following-
class="modal show"
Working Example-
<link rel="stylesheet" href="">
<script src=""></script>
<script src=""></script>
<div class="container">
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div class="modal show" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
You can try this runnable code-
$(window).load(function()
{
$('#myModal').modal('show');
});
<link rel="stylesheet" href="">
<script src=""></script>
<script src=""></script>
<div class="container">
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>

Update 2021
Bootstrap 5
Now that Bootstrap no longer requires jQuery, it's easy to show the modal using JavaScript..
var myModal = new bootstrap.Modal(document.getElementById('myModal'), {})
myModal.toggle()
