Google Analytics send event callback function

Question

I\'m trying to send an event to Google Analytics after a user is registered and before he\'s redirected. I\'m using Google Tag Manager and universal js.

Answer 1

From Google Analytic doc https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#hitCallbackNews

// Alerts the user when a hit is sent.
ga('send', 'pageview', {
  'hitCallback': function() {
    alert('hit sent');
  }
});

You can edit the hitCallback function for yours.

OR

// Use a timeout to ensure the execution of critical application code.
ga('send', 'pageview', {'hitCallback': criticalCode});
setTimeout(criticalCode, 2000);

// Only run the critical code once.
var alreadyCalled = false;
function criticalCode() {
  if (alreadyCalled) return;
  alreadyCalled = true;

  // Run critical code here...
}

Here you can define your function (criticalCode) in the above example that can ensure the data sent to Google Analytic and then work with your code.
