Question

我正在尝试使用地理编码服务，但由于某种原因地图没有显示。当我检查开发者控制台时，它不会显示任何Javascript错误。

这是谷歌地图在Chrome中显示的方式。

改变这个：

function getCoordinates(address,callback) {
    var coordinates;
    geocoder.geocode({address : address} , function (results,status){
        coords_obj = results[0].geometry.location;
        coordinates = [coords_obj.nb, coords_obj.ob];
        callback(coordinates);
    })
}

为此：

function getCoordinates(address,callback) {
    var coordinates;
    geocoder.geocode({address : address} , function (results,status){
        coords_obj = results[0].geometry.location;
        coordinates = [coords_obj.H, coords_obj.L];
        callback(coordinates);
    })
}

您的错误：coordinates = [coords_obj.nb，coords_obj.ob];

geocoder = new google.maps.Geocoder();

function getCoordinates(address, callback) {
  var coordinates;
  geocoder.geocode({
    address: address
  }, function(results, status) {
    coords_obj = results[0].geometry.location;
    console.log(coords_obj)
    coordinates = [coords_obj.H, coords_obj.L];
    callback(coordinates);
  })
}

google.maps.visualRefefresh = true;

var map;

function initialize() {
  getCoordinates('287 West Center Street Utah', function(coords) {
    var mapOptions = {
      center: new google.maps.LatLng(coords[0], coords[1]),
      zoom: 8
    };

    console.log(mapOptions)
    map = new google.maps.Map(document.getElementById('map'), mapOptions);

不要使用Google Maps Javascript API v3的未记录属性。他们可以并且每次发布时都会改变。 始终使用记录的方法（.lat（）,. lng（））。

google.maps.visualRefefresh = true;

var map;

function initialize() {
  getCoordinates('287 West Center Street Utah', function(coords) {
    var mapOptions = {
      center: new google.maps.LatLng(coords[0], coords[1]),
      zoom: 8
    };
    map = new google.maps.Map(document.getElementById('map'), mapOptions);
  })

}

google.maps.event.addDomListener(window, 'load', initialize);
var geocoder = new google.maps.Geocoder();

function getCoordinates(address, callback) {
  var coordinates;
  geocoder.geocode({
    address: address
  }, function(results, status) {
    coords_obj = results[0].geometry.location;
    coordinates = [coords_obj.lat(), coords_obj.lng()];
    callback(coordinates);
  })
