document.createElement(“script”) synchronously

Question

Is it possible to call in a .js file synchronously and then use it immediately afterward?

Answer 1

This isn't pretty, but it works:

');

Or

');
  window.onload = function() {
    functionFromOther();
  };

The script must be included either in a separate '); functionFromOther(); // Error

The same can be done with creating a node, as Pointy did, but only in FF. You have no guarantee when the script will be ready in other browsers.

Being an XML Purist I really hate this. But it does work predictably. You could easily wrap those ugly document.write()s so you don't have to look at them. You could even do tests and create a node and append it then fall back on document.write().
