Question

我编写的代码在我的位置显示标记，但是当我添加了marker.setmap方法时，地图未加载到我错了

<script type="text/javascript"
  src="https://maps.googleapis.com/maps/api/js?key=ABBByyyeessssf77Z6S8c-M-T3Ea2j-uFczWXFxKh0&sensor=true">
</script>
<script type="text/javascript">
    $(document).ready(function(){
        $(".contact_map .load").append("Loading Map...")
    });

function initialize() {
            $(".contact_map .load").empty();
    var mapOptions = {
      center: new google.maps.LatLng(22.722337, 75.881732),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
    var marker = new google.maps.Marker({
            position: myLatlng,
            title:"Hello World!"
            });
  }

  google.maps.event.addDomListener(window, 'load', initialize)
     marker.setMap(map);
</script>
<div class="contact_container">
<div class="contact_image">
</div>
    <div class="contact_map">
        <p class="load"></p>
    <div id="map_canvas"></div>
    </div>

</div>

变量标记只存在于initialize函数内部，不能在外面使用它。为此，请在函数外部定义此var。另外，我没有在任何地方看到var myLatLng

var marker;

function initialize() {
//your other code code
marker = new google.maps.Marker({ //don't use the word 'var' in this line
        position: myLatlng,
        title:"Hello World!"
        });
}

  google.maps.event.addDomListener(window, 'load', initialize)
  marker.setMap(map);
