可以在javascript中替换DOM中的根元素HTML

Question

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 eg if I want to change an attribute of the HTML element through javascript?

Answer 1

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
