If using Firebug, we can click on the HTML tab, and click to expand each element to see the generated HTML code. Is there a way to expand it all or get a plain text file?
I just accidentally found out that there doesn't even need to be Firebug. We can just press CTRL-A (to select all) on the webpage, and then right click and choose "View Selection Source", then we will get a plain text file of the "current HTML code", even will see a <div> that is the Firebug panel that is before the <body> tag if Firebug is open. But it seems like a weird way to invoke this. Is there any other way?
(Update: generated HTML usually refers to the HTML after JavaScript changes the DOM. It is the current DOM tree instead of the original source code)
