I am a beginner in javascript. As mentioned in stack overflow query, I can remove or create elements within the DOM. However, can I replace the root element through javascript e.g. if I want to change an attribute of the HTML element through javascript?

    Why would you need to replace the root element if you just want to change its attributes? – Barmar Apr 13 '15 at 03:53

I think you're asking if you can modify the element, and the answer is yes.

var html = document.getElementsByTagName('html')[0];
html.title = "Foo"; // Set an attr on the element

    You can just reference `document.documentElement`. No need to `getElementsByTagName()` – jfriend00 Apr 13 '15 at 04:31
  • True enough, I just wanted to provide a working example if the OP wanted to traverse further down the DOM and programmatically adjust other tags, like meta, for example. – sesamechicken Apr 13 '15 at 12:16
