Just discovered: jsconsole.com

Just discovered jsconsole.com, an awesome way to quickly test out some javascript code.

So far I like jsFiddle to test out javascript code in the context of a html page and css styles, or cscript to run some javascript locally in a command prompt window.

jsconsole runs in your browser but works like a console, thus you just type or paste in javascript code and will see the output in the console. Like:

a = 1;
b = 3;
a + b
A nice feature is that you can paste in functions as well and execute those:
function addit(v1,v2) { 
  return v1+v2; 
A much nicer feature is that you can load any web page to make it available as a document in your javascript context:
:load www.google.com

Loading url into DOM…

DOM load complete

You can also use that “:load” command to load any external scripts, or a javascript framework like jquery:

:load http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js

Loading script…

Loaded http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js

Now we have the google page available as a document and jquery as a library we can easily find out ( programmatically ) the text of the two buttons on that page:

$("input").each( function() {if ($(this).attr("type") == "submit") { console.log($(this).attr("value")); }});

"Google Search"

"I’m Feeling Lucky"

Isn’t hat just … wow !?
