javascript - Uncaught ReferenceError : latLng is not defined

Question

我的谷歌地图，我试图显示标记位置的纬度和经度。我收到以下错误“ Uncaught ReferenceError :latLng未定义”。我应该在此处包含什么.

我的代码如下

js:

var map;
function initialize() {
    var mapOptions = {
        center: new google.maps.LatLng(-29.3456, 151.4346),
        zoom: 2,
        scrollwheel: false,
        disableDefaultUI: false,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
}

function addMarker() {
    marker = new google.maps.Marker({
        position: new google.maps.LatLng(-29.3456, 151.4346),
        map: map,
        draggable: true
    });
}
//show the marker position

function updateMarkerPosition(latLng) {
    document.getElementById('info').innerHTML = [
        latLng.lat(),
        latLng.lng()
    ].join(', ');
}
updateMarkerPosition(latLng);
geocodePosition(latLng);

html:

<div id="info"></div>

谢谢

我想你一定是忘记初始化你的 map 了。我已经把你的 fiddle 修好了。 http://jsfiddle.net/harendra/Lt2rp/1/

  var map;
initialize();
var curlatLng=new google.maps.LatLng(-29.3456, 151.4346)
updateMarkerPosition(curlatLng);


function initialize() {
    var mapOptions = {
        center: new google.maps.LatLng(-29.3456, 151.4346),
        zoom: 2,
        scrollwheel: false,
        disableDefaultUI: false,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

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

function addMarker() {
    marker = new google.maps.Marker({
        position: new google.maps.LatLng(-29.3456, 151.4346),
        map: map,
        draggable: true
    });
}

function updateMarkerPosition(latLng) {
    document.getElementById('info').innerHTML = [
        latLng.lat(),
        latLng.lng()
    ].join(', ');
}
