§ 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);

His idea managed to be both horribly unformed and far too complex - in itself quite an accomplishment, he supposed.
