i'm a javascript noob, i just wanted to put in a page the box below DO NOT use this for Javascript. Use our Javascri开发者_C百科pt Compressor. until the top of notes

Hope someone could help me do that :)

as for request, I helped you ripped it off. Should work locally without internet connection. And fyi I ripped everything except the compression statistics. Do you need it as well? I believed you must be using it for some simple text editing.

Save this piece of code into a file called compressor.html or whatever .html you like, and run it with browser.

Disclaimer: Nothing fancy, purely ripping off the features from what you stated. And no dependencies needed, only a browser will be needed to run this code.

Tested with Chrome only, as I'm on mbp now. ;)

You don't only need the HTML source, but any linked JavaScript files as well (and the files they link to, etc).

But I think it would be illegal to just copy a whole web page, and browsers (for some reason) have stricter security settings for javascript that is run locally. If you need to do this offline, you'd better find another tool to do that. Until then, just make a bookmark to this page.
