Q:

leaflet javascript - how to clearTimeout a setTimeout on a marker?

I am adding markers like this to my map:
 map.addLayer(l), setTimeout(function() {
      map.removeLayer(l)
 }, 1e4),

which removes after 10 seconds each marker again. Now I would like to achieve that when the user clicks during those 10 seconds on a marker that the market stays visible on the map. So far I have:
l.on('click', function(e) {

console.log(e);
console.log(e.layer._leaflet_id);
console.log(l);

clearTimeout(e.layer._leaflet_id);

});

But it does now work. Any idea how I can achieve this?

A:

You need to cancel the setTimeout by calling the clearTimeout using the relevant ID. 
    var myVar;
    timeout_init();

    function timeout_init() {
        myVar = setTimeout(function(){
            $('.marker').hide();
            },5000);
    }

$( ".marker" ).click(function() {
    clearTimeout(myVar);
});
