Bing Map V8 Cluster Pass实时数据 [英] Bing Map V8 Cluster Pass real time data
本文介绍了Bing Map V8 Cluster Pass实时数据的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我只是从Bing地图开始.删除了官方文档中的几个示例.
I am just starting with Bing map. Gone through few examples in official documentation.

在上面的bing地图集群示例中，如何将TestDataGenerator数据替换为如下所示的实时数据JSON
In above bing map cluster example how to replace the TestDataGenerator data with realtime data JSON like below
mapData = [{"Name":"Point: 0","Latitude":22.0827,"Longitude":80.2707},
{"Name":"Point: 1","Latitude":24.0827,"Longitude":80.2707},
{"Name":"Point: 2","Latitude":26.0827,"Longitude":80.2707},
{"Name":"Point: 3","Latitude":28.0827,"Longitude":80.2707},
{"Name":"Point: 4","Latitude":20.0827,"Longitude":80.2707},
{"Name":"Point: 5","Latitude":22.0827,"Longitude":82.2707},
{"Name":"Point: 6","Latitude":30.0827,"Longitude":80.2707},
{"Name":"Point: 7","Latitude":22.0827,"Longitude":84.2707},
{"Name":"Point: 8","Latitude":32.0827,"Longitude":84.2707},
{"Name":"Point: 9","Latitude":18.0827,"Longitude":80.2707}];
当我在ClusterLayer中传递对象上方时，出现以下错误
When I pass above object in ClusterLayer I am getting following error
Uncaught TypeError: i[t].getLocation is not a function(…)
推荐答案
您必须遍历数据并将其转换为图钉.这是一个代码示例:
You have to loop through your data and turn it into pushpins. Here's a code sample:
var pins = [];
for(var i = 0;i < mapData.length;i++){
var pin = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(mapData[i].Latitude, mapData[i].Longitude));
//Store the original data object in the pushpins metadata so that you can access other properties like Name.
pin.metedata = mapData[i];
pins.push(pin);
}
//Now "pins" is an array of pushpins. Add them to the map or to the clustering layer.
