我使用以下示例在地图上添加了几个标记:

现在我想在用户点击标记图像时显示弹出窗口,但我找不到优雅的解决方案。有什么帮助吗?

对于初学者,在map.addLayer()函数中,您可能习惯将标记添加到地图中,需要在配置对象中设置“interactive”:true。
map.addLayer({
"id": "YOUR LAYER ID",
"interactive": true,
"type": "symbol",
"source": "YOUR LAYER SOURCE",
"layout": {
"icon-image": "YOUR LAYER ICON IMAGE",
"text-font": "Open Sans Semibold, Arial Unicode MS Bold",
"text-offset": [0, 0.6],
"text-anchor": "top"
},
"paint": {
"text-size": 12,
"icon-size": 1,
"icon-opacity": 0
}
});
之后,您需要在地图上设置点击处理程序,同时检查点是否超过您的某个功能(标记)。
map.on('click', function(e) {
console.log(e);
map.featuresAt(e.point, {radius: 100, layer: 'YOUR MARKER LAYER ID'}, function(err, features) {
console.log(features[0]);
});
});
您可以在their website查看文档以获取更多信息。如果您有任何问题,请告诉我。

考虑到最近发布的MapBox-Gl-js。它可以直接完成,只需添加弹出标记即可。
// create a simple popup.
var popup = new mapboxgl.Popup({offset: 25})
.setText('Construction on the Washington Monument began in 1848.');
// create DOM element for the marker
var el = document.createElement('div');
el.innerHTML = "Marker1";
el.id = 'marker';
// create the marker
new mapboxgl.Marker(el, {offset:[-25, -25]})
.setLngLat(monument)
.setPopup(popup) // sets a popup on this marker
.addTo(map);
休息你可以拥有自己设计的弹出窗口
var html = '<div class="marker-popup">I am a custom pop-up</div>';
var customPopUp = new mapboxgl.Popup(
{
anchor: 'bottom', // To show popup on top
offset: { 'bottom': [0, -10] }, // To prevent popup from over shadowing the marker.
closeOnClick: false // To prevent close on mapClick.
}
).setHTML(html); // You can set any valid HTML.
供参考https://www.mapbox.com/mapbox-gl-js/example/set-popup/
另一个有用的东西,要在标记上附加点击事件,您可以通过在标记元素上附加点击事件监听器来实现,例如
el.addEventListener('click', () =>
{
alert("Marker Clicked.");
}
);

以下代码段来自Mapbox-gl-js示例:Display a popup on click
map.on('click', function (e) {
var features = map.queryRenderedFeatures(e.point, { layers: ['places'] });
if (!features.length) {
return;
}
var feature = features[0];
//Use Feature and put your code
// Populate the popup and set its coordinates
// based on the feature found.
var popup = new mapboxgl.Popup()
.setLngLat(feature.geometry.coordinates)
.setHTML(feature.properties.description)
.addTo(map);
});
// Use the same approach as above to indicate that the symbols are clickable
// by changing the cursor style to 'pointer'.
map.on('mousemove', function (e) {
var features = map.queryRenderedFeatures(e.point, { layers: ['places'] });
map.getCanvas().style.cursor = (features.length) ? 'pointer' : '';
});

我也遇到了同样的问题,但是我找到了一种解决方法,而无需创建html元素。
我使用了getElement()
函数,该函数像HTML元素一样返回标记,并且在我附加了click事件之后。
this.service.getAllData().forEach(e => {
// create MapBox Marker
const marker = new mapboxgl.Marker().setLngLat([e.lon, e.lat]).addTo(this.map);
// use GetElement to get HTML Element from marker and add event
marker.getElement().addEventListener('click', () => {
alert("Clicked");
});
});
