How to format the userId in Google Analytics script?

问题

for my static HTML webside I embedded this recommended script code to every page of the side.

<script>
(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','https://www.google-analytics.com/analytics.js','ga');

ga('create', 'UA-96597161-1', 'auto');
ga('send', 'pageview');

ga('set', 'userId', {{USERID}});

The question is: how to format my known Google analytics userId into this place {{USERID}}? Is it With brackets?, with quotes? Thanks for your help.

回答1:

The analytics.js fields reference lists UserID as format type "text", which means you pass it in like you would any other string value in Javascript (i.e. in as quoted string).

In fact the same page has examples:

// Set the user ID when creating the tracker.
ga('create', 'UA-XXXX-Y', {'userId': 'as8eknlll'});

// Alternatively, you may set the user ID via the `set` method.
ga('set', 'userId', 'as8eknlll');
