Print Var in JsFiddle

To be able to see output from console.log() in JSFiddle, go to External Resources on the left-side panel and add the following link for Firebug:

https://getfirebug.com/firebug-lite-debug.js

Might not do what you do, but you can type

console.log(string)

And it will print the string into the console of your browser. In chrome push CTRL + SHIFT + J to open the console.

I have a template for this purpose; here is the code I use:

HTML

<pre id="output"></pre>

JavaScript

function out()
{
    var args = Array.prototype.slice.call(arguments, 0);
    document.getElementById('output').innerHTML += args.join(" ") + "\n";
}

Sample use (JavaScript)

out("Hello world!");
out("Your lottery numbers are:", Math.random(), 999, Math.PI);
out("Today is", new Date());

Try:

document.getElementById('element').innerHTML = ...;
