I want to retrieve the value of the
which is
<%= course.ownByStudent[i].user._id%>
in the backend.

If I understand you correctly. Let's say that the server response for course.ownByStudent[i].user._id is server_id.

So you can get the h1 element using document.querySelector('h1'), then access to the id attribute as property of the h1 element.

And the result is:

var id = document.querySelector('h1').id;
<h1 id="server_id">Hello World!</h1>

jQuery version:

var id = $('h1')[0].id;
<script src=""></script>
<h1 id="server_id">Hello World!</h1>
