问题
I need to capture the current visual state of a webpage. I have seen a few different solutions such as HTML2canvas or node-webshot. The problem is that I need to be able to capture the current state of the page rather than just the html from a given url.
E.g if a user goes to a URL and clicks on a few options which change the UI through ajax I need to be able to capture the page as it is to the user at any given time.
Basically I need to take a screenshot ( most likely using javascript ) of the current state of a web page. Im wondering if anyone has an suggestions as to what the best way to go about doing this would be?
