Uncaught ReferenceError: ga is not defined

Question

I want know how many times people clicked on a particular button (should be very simple with Google analytics). However, I had an \"Uncaught ReferenceError: ga is not defined\"

Answer 1

This is a follow on from all the others who had an issue with the Monster Insights Wordpress plugin which renames ga to __gaTracker.

I didn't want to hardcode __gaTracker in my JS (to send an event to GA) - in case someone later removed the MonsterInsights plugin and my script just stopped working.

Here is my code:

The first line creates a var called ga which is either the original ga object or the __gaTracker object if ga does not exist. Note: if ga and __gaTracker both don't exist you will end up with the same error ga is not defined
