javascript - Google Analytics multiple tracking on a single web page -

i partnership website, in order put universal analytics tracking code on single web page. website's owner has one.

i've searched on google developers , stack find how use multiple tracking codes. built code i'm not sure whether it's ok, don't want interfere data. want common analytics data in own account.

<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');    //1- create default tracker , mytracker   ga('create', 'ua-xxxxx-1', 'auto'); // default tracker   ga('create', 'ua-xxxxx-50', 'auto', 'mytracker'); // tracker    //2- pageview data of mytracker    ga(function(){       var nondefaulttracker = ga.getbyname('mytracker');       var mytrackerpageview = nondefaulttracker.get('pageview');       console.log(mytrackerpageview);    });       //3- update mytracker pageview data   ga('mytracker.set','pageview');    //4- send mytracker , default tracker pageview data   ga('send','pageview');    ga('mytracker.send','pageview');   </script> 

someone did ?

thanks!

you not need step 2 , 3. get method of tracker returns field specified in argument, , since ga not have data field called pageview undefined (which value set page path - not want this).

however pageview tracking work fine without trying retrieve values previous tracker. unless have set fields set named tracker both report same thing.
