I am now putting. for example,

  <script type="text/javascript"> Ink("$compost.htm", 69) </script>

in the HTML pages, and have added the following in a commonly-included
script file.


function Ink(Sauce, DefaultHeight) { var Fram
  // code to create and insert iFrame into DOM where called ...
  Fram = document.createElement("iframe")
  Fram.style.border = "2px solid red"
  Fram.style.width = "100%"
  Fram.style.margin = "0.5ex 0"
  Fram.style.background = "#FFE"
  Fram.onload = Inky(Fram, DefaultHeight)
  document.body.appendChild(Fram)
  Fram.src = Sauce }

function Inky(Ifr, ExHi) {
  // Autosize works in Firefox and MS IE (Edge?), else use ExHi
  setTimeout(function() { Procrustes(Ifr, ExHi) } , 500) }

function Procrustes(Ifr, ExHi) { var Ht
  try { Ht = Ifr.contentDocument.documentElement.scrollHeight }
    catch(e) { Ht = 0 }
  Ht = (Ht==0 ? ExHi + "ex" : Ht + "px") // ; alert(Ht)
  Ifr.style.height = Ht }


The setTimeout appeared necessary for the frame height needed to be
discoverable by Procrustes; perhaps there is a better way.

Sometimes, an iFrame appears further down the document than intended,
when two are adjacent.

Alas, iFrame has a minimum height.

That got rid of almost all of the iFrame onloads; a couple of special
cases needed a minor addition to the above code.
