javascript - 在传单中单击标记时不生成 map 单击事件

Question

所以，我有一张传单 map ...

var map = L.map('map').setView([35.772219, -78.675272], 17);
map.on('click', function(e) {alert('map click!')});

然后我添加一个标记...

var marker = L.circleMarker([35.772219, -78.675272]);
marker.on('click', function(e) {alert('marker click!')});
marker.addTo(map);

如果我点击标记，标记和 map 点击事件都会触发，但我只想要标记的点击事件...有什么办法可以实现吗？我似乎在文档中找不到。

L.DomEvent.stopPropagation应该做的伎俩:

Stop the given event from propagation to parent elements. Used inside the listener functions:

marker.on('click', function(e) {
    L.DomEvent.stopPropagation(e);
    console.log('marker click!')
});

还有一个演示(一个圆圈取消了它的事件，另一个没有)

var map = L.map('map').setView([35.772219, -78.675272], 10);
map.on('click', function(e) {console.log('map click!')});


var marker = L.circleMarker([35.772219, -78.68]);
marker.on('click', function(e) {
    L.DomEvent.stopPropagation(e);
     console.log('marker click!')
});
marker.addTo(map);

marker = L.circleMarker([35.772219, -78.63], {fillColor: 'red'});
marker.on('click', function(e) {
     console.log('marker click with map click')
});
marker.addTo(map);
