那是底部的 Map_canvas 吗？

        <style type="text/css">
            html { height: 100% }
            body { height: 100%;    }
            #map_canvas { height: 50% ; width:50%}
        </style>

        <script type="text/javascript"
                src="http://maps.google.com/maps/api/js?sensor=false">
        </script>
        <script type="text/javascript">
            var map;
            var marker2;
            function initialize()
            {
                var athens = new google.maps.LatLng(37.958592, 23.686191);
                var myOptions = {
                    zoom: 12,
                    center: athens,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };
                map = new google.maps.Map(document.getElementById("map_canvas"),
                myOptions);
                var marker1 = new google.maps.Marker({
                    position: athens,
                    map: map,
                    title: ""
                });

这是自动完成部分。很可能是这里的错误。//----------------------------自动完成---------- ----

             var input = document.getElementById('location');
    var autocomplete = new google.maps.places.Autocomplete(input);
    google.maps.event.addListener(autocomplete, 'place_changed', function() {
      infowindow.close();
      marker.setVisible(false);
      input.className = '';
      var place = autocomplete.getPlace();
      if (!place.geometry) {
        // Inform the user that the place was not found and return.
        input.className = 'notfound';
        return;
      }
      var address = '';
      if (place.address_components) {
        address = [
          (place.address_components[0] && place.address_components[0].short_name || ''),
          (place.address_components[1] && place.address_components[1].short_name || ''),
          (place.address_components[2] && place.address_components[2].short_name || '')
        ].join(' ');
      }
      infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
    });
    setupClickListener('changetype-geocode', ['geocode']);
    // autocomplete results:

这些功能用于标记放置，添加新的和删除以前的标记

            function putMarker(Location)
            {
                var newpos = new google.maps.LatLng(Location);
                marker2 = new google.maps.Marker({
                    position: newpos,
                    map: map,
                    title: ""
                });
            }

            function addMarker()

            {
               var Location = document.getElementById("lacation").value;
                var title= document.getElementById("mark").value;

                var newpos = new google.maps.LatLng(Location);

                marker2 = new google.maps.Marker({
                    position: newpos,
                    map: map,
                    title: title
                });


            }

            function removeMarker()
            {
                marker2.setMap(null);
            }

        </script>
    </head>

这是身体

好吧，地图无法加载（这是主要问题，但“自动完成”也失败了。也许更有经验的眼睛可以看到我看不到的错误

The main error was just a miss-type in google lilbrary. and as Dr.Molle noticed a missed bracket in the initialize();
anyway i've fixed this and i've added an array that counts and naming the markers
