How can I capture a click on the browser page without any possible effect on the site's robustness?
<p>My javascript code is added to random websites. I would like to be able to report to my server when a (specific) link/button on the a website is clicked. However I want to do it without any possible interruption to the website execution under any circumstances (such as error in my code, or my server id down etc.). In other words I want the site to do its default action regardless of my code.</p>

<p>The simple way to do it is adding event listener to the click event, calling the server synchronously to make sure the call is registered and then to execute the click. But I don't want my site and code to be able to cause the click not to complete.</p>

<p>Any other ideas on how to do that?</p>
