【问题描述】:
我已经关注了 Mapbox 网站上的 example 和 GitHub 上的 this instruction,但无法在我的地图上显示标记:
http://codepen.io/znak/pen/waPPRj(使用 Mapbox 样式和精灵) http://codepen.io/znak/pen/PqOEyV(使用自定义样式和精灵)
var center = [51.5, -0.1];
var map = new mapboxgl.Map({
container: 'map',
center: center,
zoom: 8,
style: 'https://www.mapbox.com/mapbox-gl-styles/styles/mapbox-streets-v7.json'
});
// Markers
map.on('style.load', function() {
map.addSource("markers", {
"type": "geojson",
"data": {
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [51.48, -0.08]
},
"properties": {
"title": "Lorem",
"marker-symbol": "default_marker"
}
}, {
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [51.52, -0.12]
},
"properties": {
"title": "Ipsum",
"marker-symbol": "secondary_marker"
}
}]
}
});
map.addLayer({
"id": "markers",
"type": "symbol",
"source": "markers",
"layout": {
"icon-image": "{marker-symbol}",
"text-field": "{title}",
"text-font": "Open Sans Semibold, Arial Unicode MS Bold",
"text-offset": [0, 0.6],
"text-anchor": "top"
},
"paint": {
"text-size": 14
}
});
});
所有带有标记的样式、JSON 和 PNG 文件似乎都可以正确加载。 有什么想法吗?
