Question

下面我发布了一篇由文章编辑过的代码。我只能在地图上显示一个商店位置。但是，我希望有多个位置。

以下是代码：

    <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);

        function directionsUpdated() {

        }

        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(

            // 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 () {

            showPosition(null);
        });

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

                    break;

正如尼古拉斯指出的那样，你所拥有的代码只会在地图上显示一个位置。您首先需要的是商店的数据集。许多Bing Maps客户使用Bing Spatial Data Services存储他们的商店数据，并将其作为空间REST服务公开。 http://msdn.microsoft.com/en-us/library/gg585132.aspx一旦您拥有与所需架构相匹配的数据源文件，您就可以使用Bing Maps门户将其上传到您的帐户，如下所示：http://msdn.microsoft.com/en-us/library/hh698204.aspx

拥有数据源后，您可以轻松查询数据源并让其显示您附近的商店位置。以下是一些例子：

如果您在数据库中拥有数据，则可能更愿意使用自定义Web服务公开此数据。如果是这种情况，请查看这些博客文章：
