Execute js function when a specific item is clicked

Please tell me how I can execute the go2 function when I click on the button without executing the go function

 function go($i) { alert($i); } function go2($i) { alert($i); }
 div { width: 200px; height: 200px; background: #eaeaea; }
 <div onclick="go('159');"> <button onclick="go2('160');">Go 2</button> </div>

you need to use event.stopPropagation()

 function go($i) { alert($i); } function go2($i) { event.stopPropagation(); alert($i); }
 div { width: 200px; height: 200px; background: #eaeaea; }
 <div onclick="go('159');"> <button onclick="go2('160');">Go 2</button> </div>
