How to get context path in plain HTML?

Question

I used to have a jsp page with some EL/JSTL Tags. Now I want to rewrite it in plain HTML and JavaScript (because it will be placed in a CMS).

The loading of my JavaScript fails, because I used to load it with something like this

<script
    src="${pageContext.request.contextPath}/external/jquery-3.3.1.min.js"></script>

Of course, I could try to hard code the real path, but I want a bit flexibility. So is there an equivalent of pageContext.request.contextPath in plain html?

Not sure if this helps you. Try using a CDN:

<script
  src="http://code.jquery.com/jquery-3.3.1.min.js"
  integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
  crossorigin="anonymous"></script>

It's faster, secure and doesn't need to be downloaded too. Also, you can use relative paths from the domain name, say:

<script
    src="/assets/external/jquery-3.3.1.min.js"></script>

The above works if you know where exactly the script resides.
