Google maps api 3 谷歌地图异步

我有一个GoogleMaps脚本，我正在使用它，它可以很好地使用带有脚本标记的GoogleMaps，但是我想异步加载它，并且在进行更改时遇到了困难。这就是我目前拥有的：

//<![CDATA[ 
$(window).load(function(){
var locations = [

gmarkers = [];

var map = new google.maps.Map(document.getElementById('map'), {
zoom: 16,
center: new google.maps.LatLng(42.326435, -71.149499),
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl:false
});

var infowindow = new google.maps.InfoWindow();


function createMarker(latlng, html) {
var marker = new google.maps.Marker({
    position: latlng,
    map: map
});

google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(html);
    infowindow.open(map, marker);
});
return marker;
}

for (var i = 0; i < locations.length; i++) {
/*    alert("location:"+
      locations[i][0]+":"+locations[i][2]+","+locations[i][3]);
*/
gmarkers[locations[i][0]]=
createMarker(new google.maps.LatLng(locations[i][2], locations[i][3]), locations[i][0]     
+ "<br>" + locations[i][1]);
}

/*                                                    
$(function() {
$('#locations h3 a').each(function() { 
    $(this).on('click', function() { 
        google.maps.event.trigger(marker, 'click');    
    })    
  });    
});

*/

您有两个选择

按如下所述插入脚本标记：

使用AjaxLoader：

你可以加上：

<script type="text/javascript" src="http://www.google.com/jsapi"> </script>

HTH

var映射；
函数初始化（）{
var mapOpt={
/*这是一个很好的例子*/
中心：新google.maps.LatLng（42,12），
缩放：15，
mapTypeId:google.maps.mapTypeId.ROADMAP
};
map=new google.maps.map（document.getElementById（“谷歌地图”），mapOpt）；
}

---

…在html中引用元素“

”

Google map始终是异步加载的，在这种情况下，异步加载是什么意思？嗯，你确定因为Google map api有一节专门介绍异步加载的内容，他们似乎认为这是不同的吗？而不是通过放置

google.load("maps","3.9", {"other_params":"sensor=false"});

    <script type="text/javascript">
        var map;

        function initialize() {
            var mapOpt = {
                /* le coordinate di partenza si possono impostare dal db */
                center: new google.maps.LatLng(42, 12),
                zoom: 15,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            map = new google.maps.Map(document.getElementById("googleMap"), mapOpt);

        }
