§ Adjust iframe height to contents

Some javascript in an iframe's content page can adjust the height of the iframe to its content.

Make sure the enclosing iframe has name="" and id="" exactly the same.

The window.name of a page in an iframe is the name of the iframe

 

function setParentIframeHeight() {
  var ifrm;
  if(ifrm=parent.document.getElementById(window.name)) {
    ifrm.height=500;  //or whatever. Some layouts won't shrink if a specific amount isn't set here.
    ifrm.height=document.body.scrollHeight + 30;
  }
}
function makeDoubleDelegate(function1, function2) {
  return function() {
    if (function1)
      function1();
    if (function2)
      function2();
  }
}
window.onload = makeDoubleDelegate(window.onload, setParentIframeHeight);

Oppuk gazed down at the creature in disgust.  Not only had it forced its barbaric name upon him, it smelled of floral aromatics, which the denizens of this world often applied to themselves in the mistaken belief that the natural scents of their bodies were noisome, while blatant artificial odors were somehow more acceptable.
