For reference, here's the code which ext-js uses to emulate insertAdjacentHTML:
var N = R.ownerDocument.createRange();
var S;
switch (P) {
case "beforebegin":
N.setStartBefore(R);
S = N.createContextualFragment(Q);
R.parentNode.insertBefore(S, R);
return R.previousSibling;
case "afterbegin":
if (R.firstChild)
{
N.setStartBefore(R.firstChild);
S = N.createContextualFragment(Q);
R.insertBefore(S, R.firstChild);
return R.firstChild;
}
else
{
R.innerHTML = Q;
return R.firstChild;
}
case "beforeend":
if (R.lastChild)
{
N.setStartAfter(R.lastChild);
S = N.createContextualFragment(Q);
R.appendChild(S);
return R.lastChild;
}
else
{
R.innerHTML = Q;
return R.lastChild;
}
case "afterend":
N.setStartAfter(R);
S = N.createContextualFragment(Q);
R.parentNode.insertBefore(S, R.nextSibling);
return R.nextSibling;
}
throw "Illegal insertion point -> \"" + P + "\"";

Version: (using KDE 4.2.1) Installed from: Ubuntu Packages The following javascript causes Konqueror to hit a RangeException, but it works in IE: document.createElement("div").insertAdjacentHTML("beforeEnd", "<span>foo</span>") The problem appears to be caused by the usage of range.setStartBefore(node) in the implementation of insertAdjacentHTML -- this fails with RangeException if the node has no parent. The draft HTML5 spec requires insertAdjacentHTML to be a (non-throwing) no-op for a parentless node if in "beforeBegin" or "afterEnd" mode, and to operate normally in the other two modes for a parentless node: http://www.whatwg.org/specs/web-apps/current-work/#insertadjacenthtml()
