Solution 1:

Your JSFiddle preferences are set to "onload", so the content of the JavaScript pane is wrapped in a function.

This scopes cc (dd does not exist, creating an additional problem for the jsfiddle example) to that function and stops it being a global.

Since you are trying to call it from an intrinsic event attribute, you are in a different scope and cannot access it.

As a quick fix, you can change the preference to 'nowrap', however that won't make the code conform to best practises.

It is recommended to avoid intrinsic event attributes in favour of binding event handlers with Javascript. YUI3 provides an event module and jQuery provides the on method to help with this (other libraries are available). See also: Unobtrusive JavaScript.

For example, see this js fiddle.

Solution 2:

It does, you just have two errors in your fiddle:

• You called dd instead of cc
• You wrapped your whole javascript in a onload-function (see dropdown on the left), and the variables and functions are local to that. Move it to the global scope, or assign the cc function to the global object: window.cc = function(){…};

Corrected version

Solution 3:

window.cc = function(id) { ...

the variables and functions seem to be in their on scope...
