我不知道我做错了什么。我的缩放比例太高了，而且我在地图的可见边界上没有所有的标记。

与其自己计算边界，为什么不将所有标记添加到一个，然后让传单自己从featureGroup计算边界

var featureGroup = new L.featureGroup();

L.marker([53.56440623848119,17.896099185180674],{icon: greenIcon, zIndexOffset: 20}).addTo(featureGroup); // note that "var marker =" becomes useless because you don't use var declaration afterwards;
// do this with all markers

map.addLayer(featureGroup);
map.fitBounds(featureGroup.getBounds());
