Print Var in JsFiddle

How would I print something to the result screen in JsFiddle from my JavaScript. I can't use document.write(), it doesn't allow it, neither print.

What should I use?

Solution 1:

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

Example of the result after adding firebug-lite-debug.js

Solution 2:

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());
