how know absolute position of <li> element relative browser bounds?

<html>     <body style="overflow: hidden">         <div id="ticker" style="position:absolute; white-space: nowrap;">             <ol style="list-style-type:decimal; ">                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li id="targetelem" style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>                 <li style="float: left; width: 100px; padding: 2px 0px;">test</li>             </ol>         </div>         <script type="text/javascript" src="ticker.js" language="javascript"></script>     </body> </html>

i need way know left value of element <li> id="targetelem".

borrowed http://www.quirksmode.org/js/findpos.html...

// findposition() quirksmode.org // finds **absolute** position of element on page function findposition(obj) {     var curleft = curtop = 0;    if (obj.offsetparent) {       {           /*           * loop continues until object being investigated            * not have offsetparent more. while offsetparent            * still there, still adds offsetleft of object curleft,            * , offsettop curtop.           */          curleft += obj.offsetleft;          curtop += obj.offsettop;        } while (obj = obj.offsetparent);    }     return [curleft,curtop]; }

this function should work in ie6, ie7, ie8, safari, firefox , chrome haven't tested thoroughly. also, article might relevant needs...

i hope helps.
