如何添加"点击"在mapbox-gl-js中的标记上的监听器

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]);

      });

    });

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.

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");
        });
      });
