问题描述

I use "Bootstrap v3.3.5 (http://getbootstrap.com) Copyright 2011-2015 Twitter, Inc. " for my site and i want to add google-map. I run this code, and all maps is grey. I dont understand why this not work with modal. Can someone help me?

我还包含了 <script src="https://maps.googleapis.com/maps/api/js"></script>.

HTML:

<body>
  <a class="openmodal" href="#contact" data-toggle="modal" data-id="Peggy Guggenheim Collection - Venice">Contact</a>
  <div class="modal fade" id="contact" role="dialog">
    <div class="modal-dialog modal-lg">
      <div class="modal-content" id="back">
        <div class="modal-header">
        <h4>Contact<h4>
      </div>
      <div class="modal-body">
        <div id="map"></div>
      </div>
      <div class="modal-footer">
        <a class="btn btn-default" data-dismiss="modal">Close</a>
      </div>
  </div>
</div>

JS:

<script src="https://maps.googleapis.com/maps/api/js"></script>
<script>
  function initialize() {
    var mapCanvas = document.getElementById('map');
    var mapOptions = {
      center: new google.maps.LatLng(44.5403, -78.5463),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(mapCanvas, mapOptions)
  }
  google.maps.event.addDomListener(window, 'load', initialize);
</script>

CSS:

#map {
  width: 500px;
  height: 400px;
}

这是上面的代码在一个工作小提琴 -> http://jsfiddle.net/wgur1z7n/ ^{(bootstrap 3.3.5)}

Here is the code above in a working fiddle -> http://jsfiddle.net/wgur1z7n/ ^{(bootstrap 3.3.5)}

模态显示后触发谷歌地图resize事件:

Trigger the google maps resize event after the modal is shown :

$('#contact').on('shown.bs.modal', function () {
    google.maps.event.trigger(map, "resize");
});
