PhoneGap / Cordova：Google Maps API - 放置在我的位置 [英] PhoneGap/Cordova: Google Maps API - drop pin on my position

问题描述

我可以使用Google Maps API在PhoneGap中在地图上显示我的位置。现在它只是显示地图 - 没有pindrop或任何类似的。

I am able to show my location on a map using Google Maps API in PhoneGap. Right now it just shows the map - no pindrop or anything like that. I was wondering if anyone knew how to drop a pin on the location you bring up?

我到目前为止的代码是：

The code I have so far is:

//GEOLOCATION
            var onSuccess = function(position) {
                var myLat = position.coords.latitude;
                var myLong = position.coords.longitude;

                //MAP
                var mapOptions = {
                    center: new google.maps.LatLng(myLat, myLong),
                    zoom: 14,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };

            var map = new google.maps.Map(document.getElementById("map_canvas"),
                                              mapOptions);

            };

            // onError Callback receives a PositionError object
            //
            function onError(error) {
                alert('code: '    + error.code    + '\n' +
                      'message: ' + error.message + '\n');
            }

            navigator.geolocation.getCurrentPosition(onSuccess, onError);

如果任何人都能告诉我如何在那个位置放一个pin，那真是太棒了！感谢

If anyone can tell me how to drop a pin on that location that would be really awesome! Thanks

已调整我的代码：

//GEOLOCATION
            var onSuccess = function(position) {
                var myLat = position.coords.latitude;
                var myLong = position.coords.longitude;

                //MAP
                var mapOptions = {
                    center: new google.maps.LatLng(myLat, myLong),
                    zoom: 14,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };

            var map = new google.maps.Map(document.getElementById("map_canvas"),
                                              mapOptions);

                var marker = new google.maps.Marker({
                                                    position: new google.maps.LatLng(myLat, myLong),
                                                    map: map,
                                                    title:"Hello World!"
                                                    });

            };

            // onError Callback receives a PositionError object
            //
            function onError(error) {
                alert('code: '    + error.code    + '\n' +
                      'message: ' + error.message + '\n');
            }

            navigator.geolocation.getCurrentPosition(onSuccess, onError);
