What would you like to do?
Offline Text Editor in < 140 bytes (115 bytes). Powered by localStorage & contentEditable
with({
l: localStorage // Alias for localStorage, where we'll store text content
}) with(document.body) // With the document body..
contentEditable = !0, // Turn on contentEditable
innerHTML = [l.c], // Set innerHTML of our element to the value stored in localStorage
oninput = function () { // On input..
l.c = innerHTML // store our content in localStorage
}
!function(l){with(document.body)contentEditable=!0,innerHTML=[l.c],oninput=function(){l.c=innerHTML}}(localStorage)

Edit: Thanks to help from @mathiasbynens, @subzey and @beaufortfrancois we are now down to 115 bytes from my original 136.

I use this as a JavaScript snippet or bookmarklet in Chrome to turn the current blank tab into an offline text-editor which stores what I write in localStorage. The < 140 character version can be run via console.

The original version that you can add as a bookmarklet:

(function(d){l=localStorage,k='c',q=d.body;q.contentEditable=true;q.innerHTML=l[k]||'';q.oninput=function(){l[k]=q.innerHTML;}})(document);

A demo version of this is available on JSBin.

The optimized version (115 bytes):

!function(l){with(document.body)contentEditable=!0,innerHTML=[l.c],oninput=function(){l.c=innerHTML}}(localStorage)

Pretty version

Prettier version of the implementation using document.write (hah) to write over any existing tab content, gives you some styling too:

javascript:(function(d){d.write('<body contenteditable style="font: 2rem/1.5 monospace;max-width:60rem;margin:0 auto;padding:4rem;">');var k = 'c'; var q = d.querySelector('body');q.innerHTML=localStorage[k];q.oninput=function(){localStorage[k]=q.innerHTML;}})(document);

Can someone please explain to me how to use this code as a bookmarklet?

Thanks!
