Question

What should be the simpler w

Answer 1

The simplest way is probably document.scripts

Answer 2

To get a list of scripts you can use

• document.getElementsByTagName("script"); by tag
• document.scripts; Built-in collection
• document.querySelectorAll("script"); by selector
• $("script") jQuery by selector

var scripts = document.getElementsByTagName("script");
for (var i = 0; i < scripts.length; i++) {
  if (scripts[i].src) console.log(i, scripts[i].src)
  else console.log(i, scripts[i].innerHTML)
}

// To get the content of the external script 
// - I use jQuery here - only works if CORS is allowing it

// find the first script from google 
var url = $("script[src*='googleapis']")[0].src; 

$.get(url,function(data) { // get the source 
  console.log(data.split("|")[0]); // show version info
});  

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
  console.log("Inline script");
</script>
<script>
  function bla() {
    console.log("Other inline script");
  }
</script>

Answer 3

try this

var scripts = document.getElementsByTagName("script");

Answer 4

Here you go --

(function () { 
        'use strict';
        let logscript = function () {
            let js = document.scripts;
            for (let i = 0; i < js.length; i++) {
                if (js[i].src) {
                        console.log(i, js[i].src);
                    } else {
                        console.log(i, js[i].innerHTML);
                }   
            }
        };
        if (document.readyState === 'complete') {
                logscript();
        } else {
                window.addEventListener('load', logscript);
        }
})();

Answer 5

Without jQuery :

var scripts = document.getElementsByTagName("script");

With jQuery :

var scripts = $("script");

Answer 6

You would do:

var scripts = document.getElementsByTagName( 'script' );

Now scripts is a NodeList (like an array), and you can access each one using scripts[0], scripts[1] and so on.
