Question

在这段代码中，我使用data[key].category来指示相关的Icon作为标记。但是我想用字体超棒的图标替换它，以使它在某些地方运行时轻巧，在某些地方可能会加载数十个图标作为标记

var Cofee= Leaflet.icon({
      iconUrl: '/img/Coffee.png',
      shadowUrl: '/img/pale-shadow.png',
      iconSize: [34, 49], 
      shadowSize: [49, 49],
      iconAnchor: [5, 62],
      shadowAnchor: [4, 62],
      popupAnchor: [12, -30]
});
var Store= Leaflet.icon({
      iconUrl: '/img/Store.png',
      shadowUrl: '/img/pale-shadow.png',
      iconSize: [34, 49], 
      shadowSize: [49, 49],
      iconAnchor: [5, 62],
      shadowAnchor: [4, 62],
      popupAnchor: [12, -30]
});
..
..
..

this.Getlatlng(currentlatlng, 9000).then(data => {
    for (var key in data) {
        Leaflet.marker(data[key].location, { icon: data[key].category })      
         .addTo(this.map).bindPopup('<h4>'+data[key].caption+'</h4>');
          markers.push([data[key].location.lat,data[key].location.lng]);
}

您可以使用超棒的字体图标，而不是像这样的内置标记图标：

const fontAwesomeIcon = L.divIcon({
    html: '<i class="fa fa-map-marker fa-4x"></i>',
    iconSize: [20, 20],
    className: 'myDivIcon'
});

L.marker([51.5, -0.09],{ icon:  fontAwesomeIcon}).addTo(map)
    .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')

const map = L.map('mapid').setView([51.505, -0.09], 8);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

const fontAwesomeIcon = L.divIcon({
  html: '<i class="fa fa-map-marker fa-4x"></i>',
  iconSize: [20, 20],
  className: 'myDivIcon'
});

L.marker([51.5, -0.09], {
    icon: fontAwesomeIcon
  }).addTo(map)
  .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')

#mapid {
  height: 100vh;
}

body {
  margin: 0px;
}

.leaflet-popup-close-button {
  display: none;
}

.myDivIcon {
  text-align: center;
  /* Horizontally center the text (icon) */
  line-height: 20px;
  /* Vertically center the text (icon) */
}
