标记没有使用Mapbox和传单在地图上绘图？

I am trying to plot markers from the data I receive for the server. The data is coming in and I can dump via console.log and similarly the marker is also being created as I can dump it also via console.log but the only problem is that I cannot see the marker plot on the map.

我试图从我收到的服务器数据中绘制标记。数据进来了,我可以通过console.log转储,类似地,标记也正在创建,因为我也可以通过console.log转储它,但唯一的问题是我无法在地图上看到标记图。

The code is as follows:

代码如下:

var pivotsLayer = L.mapbox.featureLayer();

function plotPivots(farm_id){
                $.getJSON('farm/' + farm_id + '/pivots', function(data){
                    $.each(data, function(pivot_i, pivot_item){
                        if(pivot_item.lat != ''){
                            console.log(pivot_item);
                            var marker = L.marker([parseFloat(pivot_item.lat), parseFloat(pivot_item.long)]).addTo(pivotsLayer);
                            console.log(marker);
                        }
                    });
                });
            }

What could I possibly be doing wrong if I can see all the information in console log?

如果我能在控制台日志中看到所有信息,我可能会做错什么?

You're not adding your L.mapbox.featureLayer (pivotslayer) to you mapinstance:

您没有将L.mapbox.featureLayer(pivotslayer)添加到mapinstance:

var pivotsLayer = L.mapbox.featureLayer();

Assuming you have a reference to your map instance in a variable called map:

假设您在名为map的变量中引用了地图实例:

var pivotsLayer = L.mapbox.featureLayer().addTo(map);
// or
map.addLayer(pivotsLayer);

I've tried your data: http://plnkr.co/edit/VjijEh?p=preview and your circle is ending up somewhere in the atlantic above antarctica. Seems the lat/lng has been swapped ;) Problem solved.

我已经尝试了你的数据:http://plnkr.co/edit/VjijEh?p = preview并且你的圈子正在南极洲大西洋的某个地方结束。似乎lat / lng已被交换;)问题解决了。
