获取 javascript 渲染页面的 html(与其交互后)

I would like to be able to save the state of the html page after I've interacted with it.

Say I click a checkbox, or the javascript set the values of various elements.

How can I save the "javascript-rendered" page?

Thanks.

That should do and will grab the ALL page not just the body

console.log(document.getElementsByTagName('html')[0].innerHTML);
