If you have a reference to the form's DOM element prior to setting `innerHTML`, it should remain valid. I found it so surprising that IE8 would get this wrong that (with apologies) I had to test it for myself. But I can easily replicate your result on IE6 - IE9: http://jsbin.com/elihi5 It only happens if you remove the form by setting `innerHTML` on its parent, though. If you remove it via DOM `removeChild`, it works correctly: http://jsbin.com/elihi5/2 So it's down to how IE handles setting `innerHTML`. Apparently, doing so destroys the parent/child relationship of the elements therein, as we can see here: http://jsbin.com/elihi5/5 If I use `innerHTML` to clear it, although my reference to the form remains valid, the form no longer has any children. If I already have a reference to one of its children, my reference remains valid, but the form still loses that child. Very surprising behavior. I suppose since `innerHTML` is a Microsoft invention and hasn't until recently been subject to any standardization, calling this "wrong" (as I did above) is harsh. But really, really surprising. Thanks for letting us know about it!  http://www.w3.org/TR/html5/apis-in-html-documents.html#dom-innerhtml -- T.J.
