Possible to put HTML page source into a variable?

[laredotornado]

Hi,

Is there a JS way to store the current page's HTML source in a
variable? Thanks, - Dave

var src = document.documentElement.innerHTML;

(Haven't checked for any cross-browser issues.)

While being very compatible for historical reasons, that would not store the
tags of the root element, the DOCTYPE declaration and anything else before
or – $DEITY forbid! – after the root element. MSHTML has .outerHTML, of
course, but ISTM that you have to serialize the missing parts yourself as
unfortunately there is no document.innerHTML.

A non-equivalent alternative is XHR:

/* or ActiveXObject(…) where necessary, like with file:// in MSHTML */
var x = new XMLHttpRequest();

x.open("GET", document.URL, false);
x.send(null);

var src = x.responseText;

In Firefox 3.6.17, not a full exact copy. Seems to regenerate from a
tokenised version or from the DOM tree. DOCTYPE not represented. And
"</li>" present, which the original did not have.

In some, but not all browsers, as I recall, the page can be loaded into
a iframe, in which it can be accessed verbatim. One browser will not
read a file from the local disc even though the current page is in the
same directory; another could, but would not read the same page as it
was showing.

document.body.innerHTML may suffice.
