How to switch markers on the map using navigation?

Question

JavaScript

Hello to all javascript monsters
Tell me how, when you click on a button, show a group of markers and when you click on another button, those markers are removed and another group appears.
jsfiddle.net/Raynor/db694go9/1 from an example of a group of markers shown on a map.
I can't get it when I click on the button first to clear the markers, then show a group of markers and when clicking on another link, show the second group of markers, and the first group should be removed from the map.
Only there is a condition that you need to use the leafletjs library, because I have a vector map built on it, and I really don’t want to switch to OpenLayers, for example -(
Thank you.
