How to insert Google Analytics after clicking a button?

问题

I'm trying to insert Google Analytics snippet after clicking a button, and therefore counting it as a visit.

Is it possible to do without needing to reload the page?

回答1:

You can use Event Tracking, namely trackPageView (found on David Walsh's site]:

_gaq.push(['_trackPageview', 'url-to-track.html']);

On a button:

var button = document.getElementsByTagName("button")[0];

button.addEventListener("click", function() {
  //Button click event
  alert("Tracking pageview");
  _gaq.push(['_trackPageview', 'url-to-track.html']);
}, false);

<button>Track me!</button>

In response to your comment:

var js = 'document.getElementsByTagName("button")[0].onclick=function(){alert("I\'m loaded!");}';

document.getElementsByTagName("button")[0].onclick = function() {
  var script = document.createElement("script");
  //Uncomment this and put the path for your file
  //script.src = "path/to/script.js";

  //Remove this, this is just for the demo
  script.innerHTML = js;

  document.body.appendChild(script);
  alert("Appended script, click the button again");
};

<button>Load a JS file</button>
<p>Or in this case, a string</p>

First save the Analytics code into a variable.

Then append it to the head tag when the button is clicked.

ga = "(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){" +
     "(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o)," +
     "m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)" +
     "})(window,document,'script','//www.google-analytics.com/analytics.js','ga');" +
     "ga('create', 'UA-XXXXXXXX-X', 'auto');" +
     "ga('send', 'pageview');"

$('a.button').on('click', function() {
  $('head').append('<script>' + ga + '</script>');
});
