解决方案
This question has been asked before in Include a Javascript File in another Javascript File. This peice of code may fit what you have been looking for
function include(filename)
{
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.src = filename;
script.type = 'text/javascript';
head.appendChild(script)
}
if that script does not work, i suggest you to look over and read the post above: Include a Javascript File in another Javascript File.
I hope this helps, it may not be the answer you had been looking for, but it may just help.
