javascript - Web scraping with bookmarklet? -

i'd use bookmarklet gather toghether few resouces different webpages.
i.e, instead of using browser extensions html elements pages, use javascript bookmarklet capture code sites.

[edit] how html elements page javascript bookmarklet?
question getting html inner code bookmarklet, not bookmarklet in general.

you don't need libraries this. create functionality in firebug or chrome inspector , format on 1 line this:

javascript:(function(){alert(1);})();

copy , paste location bar , hit enter execute it. replace alert(1); code. wrap in self-executing anonymous function or else response of execute replace web page.

if code long can write in external javascript file , see alert above create script tag src , append page.
