javascript - Including a .js file within a .js file

I'd like to know if it is possible to include a .js file within another .js file?

The reason for me wanting to do this is to keep client includes to a minimum. I have several .js files already written with functions that are needed by the client. The client would have an html file which he/she manages with a .js file include (my .js file).

I could re-write a new .js file with all the functions in it or, to avoid doing double work, figure out a way to write a .js file that includes other .js files.

Answer

I basically do like this, create new element and attach that to

var x = document.createElement('script');
x.src = 'http://example.com/test.js';
document.getElementsByTagName("head")[0].appendChild(x);

You may also use onload event to each script you attach, but please test it out, I am not so sure it works cross-browser or not.

x.onload=callback_function;
