How can get a list of the functions in a javascript file?

Question

I\'m trying to cobble together a php style include function for javascript. The route I\'m taking is through a XMLHttpRequest. The included file will load, but the functions

Answer 1

It's simple enough to use the DOM to add the required script:

function include(jsFile)
{
    var sEl  = document.createElement("script");
    sEl.type = "text/javascript";
    sEl.src  = jsFile;
    document.getElementsByTagName("head").appendChild(sEl);
}

Browsers will even download this file asynchronously, and script elements have an onload event that works in most (all?) popular browsers so you can also add a callback function if you like. The obvious downside is that functions wouldn't become available to the current script until the file is downloaded and parsed.
