Question

如何检索给定地名的经度和纬度？

Answer 1

你可以使用 The Google Geocoding API.

代表：

Check Geocode Response

Answer 2

您可以从链接按钮获取Google地图。首先右键单击地图并在此处“居中地图”，然后单击左侧窗格上的“链接”按钮，创建所需的位置中心。下一步查找ll parm。这包含经度和纬度。

示例：

 http://maps.google.com.my/?ll=3.009556,101.748505&spn=0.341477,0.676346&t=m&z=11

Answer 3

这是使用谷歌地理编码API时google.js文件中包含的两个功能 我已经用一些标记和其他更多选项重新创建它请看看它。当您为函数提供名称时，它会为您提供lat和lng。

     function load() {

        //$("#text1").autocomplete(source: arr);
        if (GBrowserIsCompatible()) {
            var map = new GMap2(document.getElementById("map"));
            map.addControl(new GSmallMapControl());
            map.addControl(new GMapTypeControl());
            var center = new GLatLng(19.11340, 72.83526);
            map.setCenter(center, 12);
            geocoder = new GClientGeocoder();
            var marker = new GMarker(center, { draggable: true });
            map.addOverlay(marker);
            document.getElementById("lat").innerHTML = center.lat().toFixed(5);
            document.getElementById("lng").innerHTML = center.lng().toFixed(5);

            GEvent.addListener(marker, "dragend", function () {
                var point = marker.getPoint();
                map.panTo(point);
                document.getElementById("lat").innerHTML = point.lat().toFixed(5);
                document.getElementById("lng").innerHTML = point.lng().toFixed(5);

            });


            GEvent.addListener(map, "moveend", function () {
                map.clearOverlays();
                var center = map.getCenter();
                var marker = new GMarker(center, { draggable: true });
                map.addOverlay(marker);
                document.getElementById("lat").innerHTML = center.lat().toFixed(5);
                document.getElementById("lng").innerHTML = center.lng().toFixed(5);


                GEvent.addListener(marker, "dragend", function () {
                    var point = marker.getPoint();
                    map.panTo(point);
                    document.getElementById("lat").innerHTML = point.lat().toFixed(5);
                    document.getElementById("lng").innerHTML = point.lng().toFixed(5);

                });

            });

        }
    }

    function showAddress() {
        load();
        var address = $("#text1").val();
        var map = new GMap2(document.getElementById("map"));
        map.addControl(new GSmallMapControl());
        map.addControl(new GMapTypeControl());
        if (geocoder) {

            geocoder.getLatLng(
      address,
      function (point) {
          if (!point) {
              alert(address + " not found");
          } else {
              document.getElementById("lat").innerHTML = point.lat().toFixed(5);
              document.getElementById("lng").innerHTML = point.lng().toFixed(5);
              map.clearOverlays()
              map.setCenter(point, 13);
              var marker = new GMarker(point, { draggable: true });
              map.addOverlay(marker);

              GEvent.addListener(marker, "dragend", function () {
                  var pt = marker.getPoint();
                  map.panTo(pt);
                  document.getElementById("lat").innerHTML = pt.lat().toFixed(5);
                  document.getElementById("lng").innerHTML = pt.lng().toFixed(5);
              });


              GEvent.addListener(map, "moveend", function () {
                  map.clearOverlays();
                  var center = map.getCenter();
                  var marker = new GMarker(center, { draggable: true });
                  map.addOverlay(marker);
                  document.getElementById("lat").innerHTML = center.lat().toFixed(5);
                  document.getElementById("lng").innerHTML = center.lng().toFixed(5);

                  GEvent.addListener(marker, "dragend", function () {
                      var pt = marker.getPoint();
                      map.panTo(pt);
                      document.getElementById("lat").innerHTML = pt.lat().toFixed(5);
                      document.getElementById("lng").innerHTML = pt.lng().toFixed(5);
                  });

              });

          }
      }
    );
        }
