私はこれに関する情報を見つけるのが十分に困難だったので、これを追加しました。
1)
KMLレイヤーを作成します。
//Define your KML layer
var MyKmlLayer= new OpenLayers.Layer.Vector("This Is My KML Layer", {
//Set your projection and strategies//
projection: new OpenLayers.Projection("EPSG:4326"),
strategies: [new OpenLayers.Strategy.Fixed()],
//set the protocol with a url//
protocol: new OpenLayers.Protocol.HTTP({
//set the url to your variable//
url: mykmlurl,
//format this layer as KML//
format: new OpenLayers.Format.KML({
//maxDepth is how deep it will follow network links//
maxDepth: 1,
//extract styles from the KML Layer//
extractStyles: true,
//extract attributes from the KML Layer//
extractAttributes: true
})
})
});
2)
KMLレイヤーのURLを設定します。
//note that I have host equal to location// //Math.Random will stop caching//
var mykmlurl= 'http://' + host + '/KML?key=' + Math.random();
3)
レイヤーを更新する間隔を設定します。
//function called// //timer// //layer to refresh//
window.setInterval(UpdateKmlLayer, 5000, MyKmlLayer);
4)
レイヤーを更新する関数:
function UpdateKmlLayer(layer) {
//setting loaded to false unloads the layer//
layer.loaded = false;
//setting visibility to true forces a reload of the layer//
layer.setVisibility(true);
//the refresh will force it to get the new KML data//
layer.refresh({ force: true, params: { 'key': Math.random()} });
//- <3 from Thqr -//
}
これが他の人にとって簡単になることを願っています。幸運を。
私はこれで何の役にも立たなかった。誰かが私のコードを見て、私が間違っていることを教えてもらえますか?ありがとうございました!

申し訳ありませんが、不完全なコードを修正する必要がありました。今回は実行する必要があります。
