Mapbox GL JS:如果单击标记,则忽略地图点击事件

我在地图上有一个标记。我想在点击它时更改其状态,并在点击地图上的其他位置时将其更改回来。

问题是点击标记时也会触发map.on("click", console.log)

我想只看到标记点击事件,因为地图点击会调用状态回滚。

var el = document.createElement('div');
el.style.backgroundImage = 'url(https://placekitten.com/g/40/40/)';
el.style.width = 40 + 'px';
el.style.height = 40 + 'px';

new mapboxgl.Marker(el)
    .setLngLat([ -63.29223632812499, -18.28151823530889 ])
    .addTo(map);

el.addEventListener('click', console.log);
map.on('click', console.log);

我认为您要做的是在用户点击标记时阻止事件被处理两次。要做到这一点,你可以使用event.stopPropagation();

请参阅:https://developer.mozilla.org/en/docs/Web/API/Event/stopPropagation

在您的代码中,您可以像这样使用它:

 function handleKitten(e) {
   e.target.style.backgroundImage = 'url(http://placekitten.com/g/50/50)';
   e.stopPropagation();
 }

 function handleMapClick(e) {
   console.log('handleMapClick', e);
 }

 var map = new mapboxgl.Map({
   container: 'map',
   style: 'mapbox://styles/mapbox/streets-v9',
   center: [-65.017, -16.457],
   zoom: 5
 });

 var el = document.createElement('div');
 el.style.backgroundImage = 'url(https://placekitten.com/g/40/40/)';
 el.style.width = 40 + 'px';
 el.style.height = 40 + 'px';

 new mapboxgl.Marker(el)
   .setLngLat([ -63.29223632812499, -18.28151823530889 ])
   .addTo(map);

 el.addEventListener('click', handleKitten, false);
 map.on('click', handleMapClick);

您可能想要使用map.once()map.off(),请参阅:Double on click event with mapbox gl
