Question

我想从地理编码器返回的结果对象中获取纬度和经度。

  var geocoder;
  var map;
  function initialize() {
    geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
      zoom: 4,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  }

  function codeAddress() {
    var address = document.getElementById("address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
        map.setCenter(results[0].geometry.location);
        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location
        });



        var inp=results[0].geometry.location;


        alert(inp);
      } else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
  }

<body onLoad="initialize()">

<!--<div id="map_canvas" style="height:80%;top:30px;right:40%;left:20%"></div>-->
 <div id="map_canvas" style="border-width:0;width:500px;height:500px;left:40px;right:60px;top:20px"></div>

  <input id="address" type="textbox" value="" style="margin-top:60px;margin-left:400px;" placeholder="Enter your Location">
    <input type="button" value="Get me There" onClick="codeAddress()">
</body>
</html>

results[0].geometry.location包含纬度和经度，但我想获得经度和纬度的单独值。我试图在results[0].geometry.location上使用像split（）和slice（）这样的javascript函数，但这不起作用。谁能告诉我怎么能这样做？

您应该可以像这样访问各个值：

var lat = results[0].geometry.location.lat();
var lng = results[0].geometry.location.lng();

从地理编码对象获取纬度
