A:
The simple solution would be
document.body.innerHTML = "";
But why on earth would you want to do this?
By the way:
var e = document.getElementsByTag('html');
should be
var e = document.getElementsByTagName('html')[0];
and
e.removeChild('body');
should be
e.removeChild(document.body);

"But why on earth would you want to do this?" suppose you wanted to just start over inserting stuff (new body...)

Thats pretty much a given, but I would guess that clearing the body is really only a symptom of bad design (code that is)

A:
- getElementsByTagName returns a collection of nodes, not a single node
- removeChild takes a node, not a string containing a tag name
var e = document.body;
e.parentNode.removeChild(e);
… however HTML documents require a body element, so this may have unexpected behavior.

By the way, I'm guessing you mean 'getElementsByTagName **returns** a ..'

Chrome will allow what? You to remove the body element? Great. So that's one browser out of … lots (present and future). Corrected the typo.

Actually, any browser will allow removing the body element. That doesn't make it a good idea.

A:
I think this will remove it
var html = document.getElementByTagName('html')[0];
var body = document.getElementByTagName('body')[0];
html.removeChild(body);

A:
document.body.parentNode.removeChild(document.body)
or
document.body = document.createElement("body")
or
while(document.body.childNodes.length != 0) document.body.removeChild(document.body.childNodes[0])
