I just learned that alert() is a method of the window object. I also just learned that getElementById() is a method of the document object.

Is there a place where I can find documentation as to what methods belong to certain objects?

Try the Mozilla Developer Network documentation. It's quite good.

For example, you can find documentation on the both window object and the document.getElementById() method.

For a quick sandbox to try stuff out, you could try jsFiddle, or even just the JS console in Google Chrome (ctrl+shift+j).

for any object, like window for example, you can do something like:

for(var prop in window){
   console.log(prop);
   console.debug(window[prop]);
}

log will tell you the name of the property and debug will show you the details

Try this place http://krook/jsdom/

Also: I'd suggest downloading Firebug addon for firefox. Use the DOM tab and you'll be able to browse which methods live where in the browser.
