Question

我的脚本如下。我必须搜索密码并根据搜索我必须在地图上显示位置

问题1：如果我有相同密码的2个结果，那么地图上还会有一个标记。我想显示单独的标记。

问题2：我想使用密码进行雷达搜索。如果密码07201和07202非常靠近区域，那么我应该得到两者的结果。我尝试在我的回复中使用radius，但它不起作用

<script>
      var map;
      <!-- var marker; -->
    function initialize() 
    { 
        var mapOptions = {
        center: new google.maps.LatLng('40.71338', '-74.193246'),
        zoom: 8,
        scrollwheel: false,
        disableDefaultUI: false,
        mapTypeId: google.maps.MapTypeId.ROADMAP
     };

      map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);

      marker = new google.maps.Marker({
                    position: new google.maps.LatLng(40.71338, -74.193246),
                    map: map,
                });


     }



    jQuery('#searchPincodeForm').submit(function (event) {
       event.preventDefault();

       var geocoder = new google.maps.Geocoder();
        var search_val=$('#country').val();

        jQuery.ajax({
                type: 'post',
                data:{
                    'pincode':search_val,                
                },
                url: 'searchPincode.php',           
                success:function(response){
                if(response != ''){

                $("#result").html(response).show();
                    geocoder.geocode({ 
                    'address': search_val }, function (results, status) {


                    if (status == google.maps.GeocoderStatus.OK) {

                    var position = results[0].geometry.location;
                        map.setCenter(position);
                        marker.setPosition(position);

                }

                })
                } else{

                    $("#result").html("Sorry Dealer not available at this location. For more information please mail at info@movemaxoil.com").show();

                }
                }


            });
            });


     </script>

Answer 1

问题出在这里：

var position = results[0].geometry.location;
map.setCenter(position);
marker.setPosition(position);

您的ajax响应中可能包含多个位置点，但在上面的代码中，您只使用了第一个位置点results[0].geometry.location。因此，不是results[0]而是必须遍历所有结果数组，以便在您的标记上映射多个点。
