下面将向主页地图添加带有主页按钮的自定义缩放控件。主页图标来自font-awesome，因此请确保包含该引用。
在这里工作。

使用Leaflet.EasyButton，一切都保持干净：命名您的图标和功能（如果需要，可以悬停文字）：
var home = {
lat: 70.3,
lng: 50.5,
zoom: 8
};
L.easyButton('fa-home',function(btn,map){
map.setView([home.lat, home.lng], home.zoom);
},'Zoom To Home').addTo(map);（放在旁边）以及使用easyButton通过tom缩放示例的答案：
// make a bar with the buttons var zoomBar = L.easyBar([ L.easyButton( '<big>+</big>', function(control, map){map.setZoom(map.getZoom()+1);}), L.easyButton( 'fa-home fa-lg', function(control, map){map.setView([home.lat, home.lng], home.zoom);}) L.easyButton( '<big>-</big>', function(control, map){map.setZoom(map.getZoom()-1);}), ]); // add it to the map zoomBar.addTo(map);
