help with load content with setTimeout

[Dralion]

i try to replicate a js-Ajax exemple from the site http://www.yensdesign.com/tutorials/contentajax/
Is to load a web page into another webpage (external) with a hiding-showing bar - up and down. BUT the new page i'v load is showing BEFORE the bar is hiding the first. So i try to find a way to clear the page before the sliding bar and put a delay to let the bar return back down and show the new page.
At this time i just try to understand SetTimeout func, but wont work. Can you guide me on my SetTimeout fonc and i appreciate some advice to fix the refresh of the new page.

case "external2":
		content.slideUp("slow");	
		setTimeout (content.load("external2.html", hideLoading),5000);
		content.slideDown("slow");
		break;

I work with dreamweaver CS3 to open the .JS file
Thanks

thank to Donk (from other web forum) to find and fix the glitch passing by jquery ressource

            case "home":
                content.slideUp("slow",function(){
                    $.ajax({
                        url :"home.html",
                        success:function(html){
                            content.html(html).slideDown("slow");
                            hideLoading();
                            }
                        })
                    })
                break;

and bypassing the setTimeout fonction
