#42I like the craziness that this devolved into. It's funny when a bunch of people are all editing like mad. I had the thought that it'd be fun to have a contest using jsfiddle to start from some point, like the excel (lite) clone in 30 lines, and add the best/coolest feature in some limit of lines. It's really wonderful how ingenuity stacks.
Such hax. I wonder if a collaborative drawing app could be made with this, using canvas.. I keep trying to figure out exactly how it works but then sparkleponies and alerts everywhere...

#43WARNING: Could there be some kind of script attack ? My Safari browser freezes with 'foo' alert message from this site and it has placed itself as default website so whenever I reopen safari it freezes again. Let me know if you know how to fix this.
I guess you could start Safari while offline to prevent the page from loading and change back your default page to something sane?

#45I think I crashed it (ie: Chrome hard lockup on the tab) with this: =location.href='google.com'
That will just throw a frame error because of the X-Frame-Options header, which is caught quickly.
Browsers tend to have more problem with =while(1){}

#46It would be nice if people could lay off the script injections. It's clearly insecure, but that's not really the point. It makes the experience worse for everyone if you alert(), etc.

No, that is the point. I even pointed it out hours ago: https://news.ycombinator.com/item?id=6727448
The failure is the lesson. The previous version was a clever hack written by a clever person. This is ignorance, and the lesson is that allowing users to run arbitrary code on other user's computers is bad idea.

#47Careful, this code runs eval() on all spreadsheet fields. Someone can "collaboratively" steal your jsfiddle.net cookies.
Yeah that was fun until I got an alert box in my face.

#48I would love to read about who/how is blocking XSS and censoring!
Oh, that's me: http://jsfiddle.net/sy85U/31/ Just a very quick, crude little hack.
added an array for blocked words;

#49Nice. I look forward to the full office suite in 60 lines of JS, the email client/server in 75 lines of JS, and of course the bitcoin exchange web app in 90 lines of JS.

#50I think the title should warn users of the various remote injection vulnerabilities present in the script. It took about 5 seconds for the page to change to xhamster
