Benytte javascript når data hentes..

Hej

Jeg bruger nedenstående Javascript når man skal vælge emne for en nyhed, og tilhørende under emne.

Men hvordan bruger jeg det når jeg i administrationen skal redigere i nyheden, dvs når nyheden hentes frem fra databasen, således at man får den rigtige undermenu, og de samme valg muligheder.

<script language = \"JavaScript\">
        function subcat()
        {
        cat = document.subad.catagory[document.subad.catagory.selectedIndex].value;
        url = \"submitad.asp?cat=\";
        url = url + cat;
        window.location.href = url;
        }
       
       
       
        function sublist(inform, selecteditem)
        {
        inform.subcatagory.length = 0
       
       
            x = 0
            subcat = new Array();
            subcatagorys = \"Organisation\"
            subcatagoryof = \"1\"
            subcatagoryid = \"Organisation\"
            subcat[x,0] = subcatagorys;
            subcat[x,1] = subcatagoryof;
            subcat[x,2] = subcatagoryid;
           
           
            if (subcat[x,1] == selecteditem){
                var option0 = new Option(subcat[x,0], subcat[x,2]) 
                inform.subcatagory.options[inform.subcatagory.length]=option0
               
            }
</Script>

<SELECT id=catagory name=catagory onChange = \"sublist(this.form, document.subad.catagory[document.subad.catagory.selectedIndex].value)\">
