Hi I am working on a Google Chrome extension for educational purposses. How I can load JavaScript script to have access to the page.

Here is my loader.js:

s = document.createElement("script");
s.src = chrome.extension.getURL("src/content_script.js");

s.onload = function(){
   this.remove();
}

document.head.appendChild(s);

and here is my content_script.js:

var formats = ytplayer.config.args.raw_player_response.streamingData.formats;
console.log("YT extension loaded!");

Problem is that I get:

Uncaught TypeError: chrome.extension.getURL is not a function at loader.js:2:26

Can someone give me suggestions on what the problem might be?

Thanks in advance!
