Question

我不会说英语，对不起这个错误。

我正在使用 bootstrap ， jquery ， propeller.in 和

https://github.com/ChadKillingsworth/geolocation-marker

我有以下代码

var map, GeoMarker;

      function initialize() {
        var mapOptions = {
          zoom: 17,
          center: new google.maps.LatLng(-34.397, 150.644),
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        map = new google.maps.Map(document.getElementById('map_canvas'),
            mapOptions);

        GeoMarker = new GeolocationMarker();
        GeoMarker.setCircleOptions({fillColor: '#808080'});

        google.maps.event.addListenerOnce(GeoMarker, 'position_changed', function() {
          map.setCenter(this.getPosition());
          map.fitBounds(this.getBounds());
        });

        google.maps.event.addListener(GeoMarker, 'geolocation_error', function(e) {
          alert('There was an error obtaining your position. Message: ' + e.message);
        });

        GeoMarker.setMap(map);
      }

      google.maps.event.addDomListener(window, 'load', initialize);

      if(!navigator.geolocation) {
        alert('Your browser does not support geolocation');
      }

问题是地图没有在div内部加载，如果我放出它正常工作的模态内容，我想知道如何在一个模态中加载地图，例子使用什么我已经

了

Answer 1

一旦模态打开，您需要初始化地图，因为地图只会加载在可见元素中。

$('#large-dialog').on('shown.bs.modal', function (e) {
  initialize();
});

Answer 2

您需要绑定事件shown.bs.modal以执行initialize函数：

$('#large-dialog').on('shown.bs.modal', function(e) {...}

并将div的维度更改为固定的。对于此示例，我设置了300px x 300px。

var map, GeoMarker;

function initialize() {
  var mapOptions = {
    zoom: 17,
    center: new google.maps.LatLng(-34.397, 150.644),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'),
    mapOptions);

  GeoMarker = new GeolocationMarker();
  GeoMarker.setCircleOptions({
    fillColor: '#808080'
  });

  google.maps.event.addListenerOnce(GeoMarker, 'position_changed', function() {
    map.setCenter(this.getPosition());
    map.fitBounds(this.getBounds());
  });

  google.maps.event.addListener(GeoMarker, 'geolocation_error', function(e) {
    alert('There was an error obtaining your position. Message: ' + e.message);
  });

  GeoMarker.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);

if (!navigator.geolocation) {
  alert('Your browser does not support geolocation');
}


$('#large-dialog').on('shown.bs.modal', function(e) {
  initialize();
});

html,
body,
#map_canvas {
  margin: 0;
  padding: 0;
  height: 300px;
  width: 300px
}
