这里是我用JavaScript编写的在地图上渲染标记并适配地图边界的代码。
地图边界根据geojson进行适配,但问题在于当地图上有任何标记并尝试适应边界时,地图瓦片图像未能渲染。
地图上仅显示标记,没有瓦片图像。
var latLongCollection = [];
var map;
$(document).ready(function() {
map();
});
function map() {
map = L.mapbox.map('DivId', 'ProjectId');
GetData();
}
function GetData() {
$.ajax({
type: "GET",
url: someUrl,
dataType: "json",
contentType: "application/json; charset=utf-8",
success: AjaxSuccess,
error: function () {
}
});
}
function AjaxSuccess(data) {
if (data == null || data.length == 0) {
return;
}
var geoJson = {
"type": "FeatureCollection",
"features": []
};
$.each(data, function (index, value) {
var latitude = parseFloat(value.Latitude),
longitude = parseFloat(value.Longitude);
if (latitude && longitude) {
var dataJson = {
type: "Feature",
geometry: { type: "Point", coordinates: [longitude, latitude] },
properties: {
someProp: value.SomeProperty,
}
};
geoJson.features.push(vehicleJson);
}
});
var markerLayer = L.mapbox.featureLayer(geoJson).addTo(map);
markerLayer.eachLayer(function (marker) {
var feature = marker.feature;
var featureProperty = feature.properties;
if (featureProperty.someProp) {
marker.setIcon(L.divIcon({
html: 'htmlstring',
iconSize: [35, 75]
}));
}
else {
marker.setIcon(L.divIcon({
html: 'anotherhtmlstring',
iconSize: [35, 75]
}));
}
latLongCollection.push(marker._latlng);
});
markerLayer.on('click', function (e) {
map.panTo(e.layer.getLatLng());
});
if (latLongCollection.length > 0) {
map.fitBounds(latLongCollection);
}
}
