Fscommand and mixed navigation

I am using the following AS to load html data into a <div id="content></content>

on (release, releaseOutside) {
   fscommand("loadPage", "about.html");
}

I also want to load additional content into the same DIV from conventional HREF links. Do I use a variation of the above?

<script type="text/javascript">
// You can put in some stuff to show while it loads the page
 
var loadingmessage = "Loading page... Please wait";
var xmlHttp;
function createRequest(){
    if(window.ActiveXObject) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); }
    else if(window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); }
}
function loadPage(pageurl){
    // It puts the <div> in a variable here, so it can write to the tag.
    var content = document.getElementById("content");
    // Here the variable loadingmessage is put in, so it will be shown until the page is downloaded.
    content.innerHTML = loadingmessage
    createRequest();
    var url = pageurl;
    xmlHttp.open("GET", url, true);
    // Here you tell it to run this function when it has fetched the content - pretty much like a flash listener
    xmlHttp.onreadystatechange = pageLoaded;
    xmlHttp.send(null);
}
function pageLoaded() {
    var content = document.getElementById("content");
    if(xmlHttp.readyState == 4) {
        // Dont ask me about the readyStates, but this works (Read the tutorial i posted)
        // The content is here written to the <div>, replacing the loadingmessage variable - voila!
        content.innerHTML = xmlHttp.responseText;
    }
}
 
</script>
<SCRIPT LANGUAGE="JavaScript"> 
<!--  
function flashmenu_DoFSCommand(command, args) { 
 if (command == "loadPage") { 
  loadPage(args);
 }
}
//--> 
</SCRIPT> 

<SCRIPT LANGUAGE="VBScript">
<!-- 
// Catch the fscommand in ie with vbscript, and pass
// it on to JavaScript.
Sub flashmenu_FSCommand(ByVal command, ByVal args)
    call flashmenu_DoFSCommand(command, args)
end sub
//-->
</SCRIPT>
