Javascript: How Can I Know Where Is The .js Self?

I write a small javascript library, it use a image. I want to build the directory structure like this: /lib /mylib main.js /img main.png /other librari

Solution 1:

You can extract it from your <script> tag:

function getScriptPath() {
  var scriptTags = document.getElementsByTagName('script');

  return scriptTags[scriptTags.length - 1].src.split('?')[0].split('/').slice(0, -1).join('/') + '/';
}
