Question

I’m trying to dynamically load an image from a javascript file.

How I can load it using Assets (or FOSJsRoutingBundle) without having to paste my code of the .js file into the template?

Answer 1

you could post PHP generated JS variable and later use it in you JS files.

for example:

<script>
var image_path = '{{ asset('your/path/to/image') }}';
</script>

in case you need this path in the section, where typically JS files are included, you can always use twig blocks.
