Sql item - get url from page

Question

Hi I'm trying to display a menu from a table, and then I want to mark the current page in that menu by reading the url of the current page.
This is what i've got so far:
DECLARE
loc Varchar2(40);
BEGIN
loc := htp.script('document.url');
htp.print('<table border=1>');
for rec in (select id, name, parent_id, url from fgj_menu where parent_id=0) loop
   HTP.print ('<tr>');
   HTP.print ('<td><a href="' || rec.url || '">' || rec.name || '</a></td></tr>');
   for rec2 in (select id, name, parent_id, url from fgj_menu where parent_id = rec.id) loop
if rec2.url = loc then
   HTP.print ('<tr>');
   HTP.print ('<td>  >> <a href="' || rec2.url || '">' || rec2.name || '</a></td></tr>');
else
   HTP.print ('<tr>');
   HTP.print ('<td>    <a href="' || rec2.url || '">' || rec2.name || '</a></td></tr>');
end if;
end loop;
END LOOP;
htp.print('</table>');
END;fails on 4th line :
loc := htp.script('document.url');Any suggestions?

Hi Botzy
You can put your javascript code in an HTML portlet, but I prefer to put a page under htdocs, it's much easier to develop, and then use an url item that displays the url directly in the page.
About the code :
var xhr_object = null;
if(window.XMLHttpRequest) // Firefox
     xhr_object = new XMLHttpRequest();
else if(window.ActiveXObject) // IE
     xhr_object = new ActiveXObject("Microsoft.XMLHTTP");
xhr_object.open("POST", "/portal/pls/portal/my_schema.my_proc", true);
xhr_object.onreadystatechange = function()
if(xhr_object.readyState == 4) alert(xhr_object.responseText);
xhr_object.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr_object.send('p_param1=value1&p_param2=value2');
That's really simple to use, you just have to change the name of your proc and its parameters, and you'll get what it "htp.prints". Be sure to grant exec to public on you proc.
By the way, I've just imagined an even more simple solution :
- do not pass any param to your procedure. Let it just write always the same code whatever the page it is on
- identify each entry of your menu with a javascript id, for instance
<table>
<tr><td id="url1">page 1</td></tr>
<tr><td id="url2">page 2</td></tr>
etc...
Then use a small javascript code at the end of your page with something lie this :
document.getElementById(document.location.href).style = a different color
or
document.getElementById(document.location.href).innerHTML = something different
or whatever you want.
