What am I doing wrong when my fiddle isn't working? I can't see the blue dot to start measuring my path or area (same problem like in my localhost environment project)...
http://jsfiddle.net/a6pp9vwz/9/ working for me.
Console log said "
$ not defined".
$ is a jQuery class, so you need a jQuery environment to enable AJAX requests. You can enable jQuery in JSFiddle in the "Frameworks & Extensions" tab.
