Acquire Asset Path from JavaScript

Question

I need to display images on an HTML5 canvas that are in the Rails asset pipeline, but I need to know the path for the asset from JavaScript. I\'m using js-routes for other parts

Answer 1

In the Rails Asset Pipeline guide, they give an example of coding assets in your stylesheets by preprocessing the stylesheets with ERB. You can use the same technique with JavaScript, assuming you tack an .erb to the end of the filename:

var someAssetPath = "<%= asset_path('some_image.png') %>";
