[TYPO3] How do I get the page id in TMENU?

[Mike]

I have a HMENU/TMENU thing set up.  I want each hyperlink in the menu 
to call a javascript function and pass it's page id number.  How do I 
get the page id number in my TMENU?    (see the question marks (????) 
below, I want them to be the page id of that page:)

...
temp.redmenu.2 = TMENU
temp.redmenu.2 {

   NO.allWrap = <li class="sub_menu_li"> | </li>

   NO.ATagParams = class = "rednavsublink" onmouseover="callfunction(??????)"

}
