 #map { width: 100%; height: 300px; border: 0px; padding: 0px; }

尝试这个..它将起作用在脚本中：

var myCenter=new google.maps.LatLng(10.123,11.989);
var marker;
function initialize()
{
    var mapProp = {
    center:myCenter,
    zoom:5,
    mapTypeId:google.maps.MapTypeId.ROADMAP 
   };
    var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
    var marker=new google.maps.Marker({
    position:myCenter,
    animation:google.maps.Animation.BOUNCE
  });
   marker.setMap(map);
}

在html中：

 <div id="googleMap" style="width:1400px;height:620px;">
