如何創建多個商店？

Question

下面，我發布了一些文章中編輯的代碼。 我只能在地圖上顯示一個商店位置。 但是，我希望有多個位置。

這是代碼：

    <div id="manualEntry">
    Your current location
    <input id="manualAddress" type="text" style="width: 500px" />
    <input id="getManualDirections" type="button" value="Get Directions" />
</div>
<div id="mapContainer" style="height: 500px">
    <div style="float: left">
        <div id="directionsMap" style="float: none; position: relative; width: 720px; height: 400px">
        </div>
    </div>
    <div id="directionsList" style="float: left; overflow: auto; width: 250px; height: 400px">
    </div>
</div>
<script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
<script type="text/javascript">
    $(function () {
        var map = null;
        var directionsManager = null;
        var location = null;
        var STORE_LOCATION = "San Jose, CA";


        showManualEntry();

        $("#askPermission").hide();
        loadMap();
        // Get the location
        var options = {
            enableHighAccuracy: true,
            timeout: 20000,
            maximumAge: 2000
        };
        navigator.geolocation.getCurrentPosition(showPosition, positionError, options);

        function loadMap() {
            // Initialize the map
            if (!map) {
                map = new Microsoft.Maps.Map(document.getElementById("directionsMap"),
                         { credentials: "YOUR_BING_MAPS_KEY" });
            }
        }

        function showPosition(position) {
            map.entities.clear();
            if (position) {
                location = position.coords;
                map.setView({ zoom: 15, center: new Microsoft.Maps.Location(location.lattitude, location.longitude) })
            }
            if (!directionsManager) {
                Microsoft.Maps.loadModule('Microsoft.Maps.Directions', { callback: createDirectionsManager });
            }
            else {
                createDirectionsManager();
            }
        }

        function createDirectionsManager() {
            var displayMessage;
            if (!directionsManager) {
                directionsManager = new Microsoft.Maps.Directions.DirectionsManager(map);
                displayMessage = 'Directions Module loaded\n';
                displayMessage += 'Directions Manager loaded';
            }
            directionsManager.resetDirections();
            directionsErrorEventObj = Microsoft.Maps.Events.addHandler(directionsManager, 'directionsError', directionsError);
            directionsUpdatedEventObj = Microsoft.Maps.Events.addHandler(directionsManager, 'directionsUpdated', directionsUpdated);
            createDrivingRoute(location);

        function directionsUpdated() {
            // Show Success message if required
        }
        function directionsError(args) {
            // Show Error message if required
        }

        function createDrivingRoute(coords) {
            if (!directionsManager) { createDirectionsManager(); }
            directionsManager.resetDirections();
            // Set Route Mode to driving 
            directionsManager.setRequestOptions({ routeMode: Microsoft.Maps.Directions.RouteMode.driving });
            var fromWayPoint = null;
            if (coords != null) {
                fromWayPoint = new Microsoft.Maps.Directions.Waypoint(
                                {

            }
            var toWayPoint = new Microsoft.Maps.Directions.Waypoint({ address: STORE_LOCATION });
            directionsManager.addWaypoint(toWayPoint);
            // Set the element in which the itinerary will be rendered
            directionsManager.setRenderOptions({ itineraryContainer: document.getElementById('directionsList') });
            directionsManager.calculateDirections();
        }


        function showManualEntry() {
            $("#manualEntry").show();
        }

        $("#getManualDirections").click(function () {
            loadMap();
            showPosition(null);
        });

        function positionError(position) {
            switch (position.code) {
                case 1:
                    showManualEntry();
                    break;

正如Nicolas指出的那樣，您擁有的代碼只會在地圖上顯示一個位置。 您首先需要的是商店的數據集。 許多Bing Maps客戶使用Bing空間數據服務來存儲他們的商店數據，並將其作為空間REST服務公開。 http://msdn.microsoft.com/zh-cn/library/gg585132.aspx一旦您擁有與所需架構匹配的數據源文件，您可以使用Bing Maps門戶將其上傳到您的帳戶，如此處所述： http：// /msdn.microsoft.com/en-us/library/hh698204.aspx

有了數據源后，您就可以輕松查詢該數據源，並顯示附近的商店位置。 這里有些例子：

如果您將數據存儲在數據庫中，則可能更喜歡使用自定義Web服務公開此數據。 如果是這種情況，請查看以下博客文章：
