Redirection url in Adobe Analytics

I have a simple html page in order to test locally the Adobe Analytics.

I try to implement analytics for url.

I have a simple url with onClick event like this:

<a href="https://www.youtube.com/" onClick="s.tl(this,'e','youtube')">Youtube</a>

Using the official at page 223 I found the following variables:

s.referrer="https://www.youtube.com/"s.pageURL="https://www.youtube.com/"

I add them to my code but the problem persists again. What can I do in order to fix the server call problem?

Solved using this:

<a href="https://www.youtube.com/" onClick="s.tl(this,'e','youtube',null,'navigate');return false">Youtube</a>
