Google Maps APIの複数のマップをC#ASP.NETアプリケーションのページに追加したいと思います。ただし、現在のコードでは、最後のマップのみが表示されます。マップを含む必要がある他のすべてのdivは空です。私のコードでわかるように、マップにはすでに一意の名前が付いています(良い方法ではありませんが、一意です)。誰かが私が間違っていることを説明できますか?よろしくお願いします。
Googleを初期化する:
protected void loadGoogle()
{
var googleScript = "function loadScript() {" +
"var script = document.createElement(\"script\");" +
"script.type = \"text/javascript\";" +
"script.src = \"http://maps.google.com/maps/api/js?sensor=false& callback=initialize\"; " +
"document.body.appendChild(script);" +
"}" +
"window.onload = loadScript;";
ClientScript.RegisterStartupScript(typeof(Page), "CreateGoogleMapScript", googleScript, true);
}
マップを作成する(複数回呼び出される):
protected void createMap(String mapId, String address)
{
var script = "function initialize() {" +
"var geocoder = new google.maps.Geocoder();" +
"var latlng = new google.maps.LatLng(-34.397, 150.644);" +
"var mapOptions" + mapId + " = {" +
"zoom: 16," +
"center: latlng," +
"mapTypeId: google.maps.MapTypeId.ROADMAP" +
"};" +
" var map" + mapId + " = new google.maps.Map(document.getElementById(" + mapId + "), mapOptions" + mapId + ");" +
"var address = \"" + address + "\";" +
"geocoder.geocode( { 'address': address}, function(results, status) {" +
"if (status == google.maps.GeocoderStatus.OK) {" +
"map" + mapId + ".setCenter(results[0].geometry.location);" +
"var marker = new google.maps.Marker({" +
"map: map" + mapId + "," +
"position: results[0].geometry.location" +
"});" +
"} else {" +
"alert(\"Geocode was not successful for the following reason: \" + status); " +
"}" +
"});" +
"}";
ClientScript.RegisterClientScriptBlock(typeof(Page), "CreateMapScript"+mapId, script, true);
}
呼び出し元:
whileループ、literal.Text
新しいdivを追加し、その後にcreateMap(mapId, address);
アップデート:
私の新しいコード:
var script = "function initialize() { var geocoder = new google.maps.Geocoder();";
for (int i = 0; i < maps.Count; i++)
{
String currentId = maps[i] as String;
String currentLocation = locations[i] as String;
script += " " +
"var latlng = new google.maps.LatLng(" + 500 + "," + 400 + ");" +
"var myOptions = {" +
"zoom: 16," +
"center: latlng," +
"mapTypeId: google.maps.MapTypeId.ROADMAP" +
"};" +
"var map = new google.maps.Map(document.getElementById(\"" + currentId + "\"), myOptions);" +
"var address = \"" + currentLocation + "\";" +
"geocoder.geocode( { 'address': address}, function(results, status) {" +
"if (status == google.maps.GeocoderStatus.OK) {" +
"map.setCenter(results[0].geometry.location);" +
"var marker = new google.maps.Marker({" +
"map: map," +
"position: results[0].geometry.location" +
"});" +
"} else {" +
"alert(\"Geocode was not successful for the following reason: \" + status); " +
"}" +
"});";
}
script += "};";
これですべてのマップが描画されますが、正しい場所にあるのは最後のマップだけです。他のものはlatlng変数に基づいています。ジオコーダーを複数回使用できないのはなぜですか?
