Load external js file in another js file

Question

I have this file include in my html and I want to call it from another javascript. Please suggest me how should I do it?

<script type="text/javascript" src="js.js">/*
  old:123
  new: 456*/
</script>

I want to include it in my js file, not in the html.

You want to do what? Also.. that way of using JavaScript blocks is invalid and won't work/ — putvande, Aug 15 '13 at 20:29

script block is in the html's head.. not in the js file. I want to do the same using another js file. — Gaurav, Aug 15 '13 at 20:32
You can use server side languages to generate dynamic js scripts so calling it with a parameter will generate something else. Thats all i can offer — zardilior, Jun 10 '16 at 15:55

If you want to include a JS file in a JS you can use jQuery.getScript() for that

$.getScript('another_file.js', function() {
    //script is loaded and executed put your dependent JS here
});

And if you cannot use jQuery

var imported = document.createElement('script');
imported.src = '/path/to/imported/script';
document.head.appendChild(imported);

For more information about the current CSP3 spec from W3 look here.
