Table of contents problem (iframe linking) fixed

Yesterday I was able to fix the Javascript code that prevented the left-side table of contents from working properly in the Safari and Google Chrome browsers. I tweaked a solution suggested in an online comment (#7) by “inimino” at Targeting an anchor within iFrame; his(?) original code is in the source of this page.

function scrollToFrag(frag){

// Called by clicking on a link in the left-side table of contents in the main page.

// The argument ‘frag’ is the element identifier of a paragraph in the agreement draft,

// which is located is is in an iframe (‘ContentFrame’) on the right of the main page.
  objTemp=top.frames["ContentFrame"].document.getElementById(frag);

  objTemp.style.display=’block’;

  tmp = getPos(objTemp);

    // getPos is a routine that determines where in the document

    // the ‘frag’ paragraph is located

  top.frames["ContentFrame"].scrollTo(0,tmp);

    // I had to prepend the ‘top.frames["ContentFrame"].’ part

    // to make it work in Safari and Google Chrome.

    // The original code is more succinct; I expanded it

    // for debugging purposes.

}
function getPos(e) {

  var y=0;

  do{

    var yd = e['offsetTop'];

    y += isNaN(yd)?0:yd;

    e = e.offsetParent;

    } while (e && e!=document.body);

  return y;

  }
