Is there a way to access the page HTML source code using javascript?

I know that I can use document.body.innerHTML but it contains only the code inside

    For IE you can also use: document.all[0].outerHTML

    Use 

    document.documentElement.outerHTML

    or 

    document.documentElement.innerHTML

    One way to do this would be to re-request the page using XMLHttpRequest, then you'll get the entire page verbatim from the web server.

    This can be done in a one-liner using XMLSerializer.

    var generatedSource = new XMLSerializer().serializeToString(document);

    Which gives String

    <!DOCTYPE html><html><head>

<title>html - javascript page source code - Stack Overflow</title>
...

    Provided that

    • true html source code is wanted (not current DOM serization)
    • and that the page was loaded using GET method,

    the page source can be re-downloaded:

    fetch(document.location.href)
    .then(response => response.text())
    .then(pageSource => /* ... */)
