jsfiddle example works, won't run in my jsfiddle account editor

Question

This works fine

https://jsfiddle.net/blazeeboy/fNPvf/

I copied it precisely to my account & editor here, and it won't work. No action on pressing the "submit" button.

https://jsfiddle.net/user/digitareous/fiddles/

function change(){

var myNewTitle = document.getElementById('myTextField').value;
if( myNewTitle.length==0 ){
       alert('Write Some real Text please.');
   return;
   }

  var title = document.getElementById('title');
   title.innerHTML = myNewTitle;

   }

I looked at jsfiddle "getting started" and "beginning tutorial" pages looked for other such starting points, and clicked all around in jsfiddle, run, update, etc. I also built a fiddle from the tutorial and tried to run it, no joy. Tried IE11, Chrome and Firefox. I could not get any of them make the jsfiddle run.

Something is making my jsfiddle editor "inactive".

What might that be?

Answer 1

In the second jsfiddle click on the javascript settings button (top right corner of the javascript code field of the editor) and in the popup field "LOAD TYPE" select "no wrap - in head".

You should now get the desired behavior.

(I get stuck on this from time to time - it is very frustrating).
