JsFiddle not working in Chrome

Question

I recently created a fiddle with the following code -

HTML

<button onclick="action();">click me<img src="http://dummyimage.com/200x200/000000/fff.gif&text=Image+1" width="200px" id="ImageButton1"></button> 

Js

 function action ( ) { if(document.getElementById("#ImageButton1").src == 'http://dummyimage.com/200x200/000000/fff.gif&text=Image+1' ) document.getElementById("#ImageButton1").src = 'http://dummyimage.com/200x200/dec4ce/fff.gif&text=Image+2'; else document.getElementById("#ImageButton1").src = 'http://dummyimage.com/200x200/000000/fff.gif&text=Image+1'; } 

Link to the script - http://jsfiddle.net/QVRUG/4/

This code works in FF and in the local html file, but throws an error in the chrome console -

 Uncaught ReferenceError: action is not defined 

Next, I investigated the error and found -

Unused ReferenceError for function defined in onload function

So I tried too -

 window.action = function(){...code here...}; 

But no luck :(

Please let me know about this behavior, why it doesn’t work in Chrome and works for others. Please do not just specify the patch to make the violin work, as I am also interested in the behavior. The descriptive answers (with the appropriate link for further study) are really appreciated in this case so that I can move correctly in my other projects.

Let me know if the question is not on the track, I will remove it (although I have made my honest efforts to make the question clean and understandable)

Answer 1

This is because the "language" is set as Javascript 1.7 in jsFiddle.

Why does this only work in Firefox?

According to version history , 1.7 was only supported in Mozilla Firefox, so why it works there and not in other browsers.

Decision:

Change the language from Javascript 1.7 to Javascript in the Languages section of your jsFiddle and it will work. I assume that you must have changed it to 1.7, because the default is usually just Javascript (you can see this by pasting your code into a new jsFiddle where it will work as expected).
