yii2-google-analytics's Issues

Renaming the Global Object

In some cases the ga variable name might already be used by an existing object on your page. To avoid overriding your existing object, you can rename the ga function, for example to __gaTracker. To do this, simply replace the ga parameter in the snippet above:

(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','__gaTracker');

Testing on localhost

In some cases you might want to test analytics.js from a webserver running on localhost. To set analytics.js cookies, you need to disable the default cookie domain using:

ga('create', 'UA-XXXX-Y', {
  'cookieDomain': 'none'
});

Add debugging

Documentation

Debugging

You can enable the debug version of analytics.js by using analytics_debug.js:

(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_debug.js','ga');
ga('create', 'UA-XXXX-Y', 'auto');
ga('send', 'pageview');

This should only be used temporarily or during development, as analytics_debug.js is larger and will delay hits to google-analytics.com.
Trace Debugging

Trace debugging will output more verbose information to the console. To enabled trace debugging, use https://www.google-analytics.com/analytics_debug.js and this line of code before the snippet.

window.ga_debug = {trace: true};

Alternative Asynchronous Snippet

While the canonical analytics.js snippet described above ensures the script will be loaded and executed asynchronously on all browsers, it has the disadvantage of not allowing modern browsers to preload the script.

The alternative snippet below adds support for preloading, which will provide a small performance boost on modern browsers, but can degrade to synchronous loading and execution on IE 9 and older mobile browsers which do not recognize the async attribute. We suggest you use this snippet if your visitors primarily use modern browsers to access your site.

<!-- Google Analytics -->
<script async src='//www.google-analytics.com/analytics.js'></script>
<script>
window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;
ga('create', 'UA-XXXX-Y', 'auto');
ga('send', 'pageview');
</script>
<!-- End Google Analytics -->

add 0.1.1 or 0.2.0 tag

Could you add a tag for the latest change (additional attribute).
0.1.1 would be fine with semver.

Add GA plugins support

Collect list of all available parameters

Need to create a list of all available parameters and their examples for Universal Google Analytics to add implement them later.
