 mapNavigation: {
   enabled: true,
   enableDoubleClickZoomTo: true
 },

Answer 1

Use mapZoom after click event. In click event you have access to values of clicked place on a map.

Note: You may need to create some if-else statement, to prevent clicks on legend, +/- buttons etc.

Answer 2

you can use zoomTo() , it'll zoom to a particular point wherever you have clicked 
here is a fiddle

oneclickzoomTo()
