Accessing currently executing JavaScript path when jQuery's getScript() Method is used

Question

I have a JavaScript file, which needs to know from which location it is loaded. My requirement is similar to How may I reference the script tag that loaded the currently-executing script?

I am using

document.currentScript;

to get the script path. But this implementation is breaking if my JavaScript file is loaded using jQuery's getScript() Method:

$(document).ready(function(){
  $("button").click(function(){
    $.getScript("my_script.js");
   });
});

When I do this, document.currentScript always returns null. Is there a work around to fix this issue?

`$.getScript` doesn't use a script tag, it uses ajax with the `script` dataType to get and load the script, which is why `currentScript` probably is null. Why do you need to know which location the script was loaded from, it seems like a X/Y problem, and the really simple solution is to just check for a certain element in the current DOM to see what page you're on. — adeneo, Jan 11 '16 at 15:36
My script file could change regularly and I have no control over who uses it. So if my script is not loaded from my domain, I simply log a message indicating to developers that they should check if script has been updated. Can you please share more information on "check for a certain element in the current DOM to see what page you're on." — Vishvesh, Jan 11 '16 at 16:30
Did you try using `document.domain` to get the current domain in your script file — adeneo, Jan 11 '16 at 16:31
Hey Thanks. This gives me the domain name. document.documentURI gives the complete URL. Can you please post this as the answer? — Vishvesh, Jan 11 '16 at 16:44

Try using $.ajaxSetup() , beforeSend

$.ajaxSetup({
  beforeSend:function(jqxhr, settings) {
    // do stuff with path to current `url`
    console.log(settings.url)
  }
})

I added this before making call to "getScript("my_script.js");". The log in this method gives a url, but how do I access the information in my script file. Since my script is not added to script dataType. – Vishvesh Jan 11 '16 at 16:35
Is requirement to return text of `"my_script.js"` ? – guest271314 Jan 11 '16 at 16:39
yes. document.documentURI seems to be working. But I need to test it. – Vishvesh Jan 11 '16 at 16:45
