在下面的屏幕截图中,您可以看到一个标记为 Mother Earth Brewery 的标记,但它应该是 Dogfish Head:
我添加地图框标记的代码是:
var lat;
var lng;
var markers = [];
var markerTemp;
for (i = 0; i < data.length; i++) {
lat = parseFloat(data[i].lat);
lng = parseFloat(data[i].lng);
if (lat == "" || lng == "") {
} else {
L.marker([lat, lng]).addTo(map).bindPopup(data[i].brewery);
markerTemp = L.marker([lat, lng]);
markers.push(markerTemp);
alert("Brewery: " + data[i].brewery + "Lat: " + lat + "Long: " + lng );
}
var group = L.featureGroup(markers);
map.fitBounds(group.getBounds());
}
变量数据是下面解析的json:

在代码中你可以看到我添加了这个alert("Brewery: " + data[i].brewery + "Lat: " + lat + "Long: " + lng );
以确保正确的值进入
markerTemp = L.marker([lat, lng]);
markers.push(markerTemp);
我通过警报一一验证了正确的数据,并与 JSON 的输出进行了比较。一切看起来都正确,我被卡住了,第二组眼睛将不胜感激。谢谢!
