Question

嗨，我正在使用带有4个输入的Google商家信息自动填充功能，自动完成工作正常，但只显示最后一个输入的标记和信息窗口。有人能告诉我问题出在哪里以及为什么其他输入的标记和信息窗口没有出现在地图上？任何答案都表示赞赏。

解决问题的一种方法：

<script>
var map = null;
          var autocompleteOptions = {
           componentRestrictions: {country: "az"}
          };

function setupAutocomplete(autocomplete,inputs,i) {
            autocomplete[i] = new google.maps.places.Autocomplete(inputs[i], autocompleteOptions);
            autocomplete[i].bindTo('bounds', map);

            google.maps.event.addListener(autocomplete[i], 'place_changed', function() {
              var infowindow = new google.maps.InfoWindow();
              var marker = new google.maps.Marker({
                    map: map
              });  
              infowindow.close();
              marker.setVisible(false);
              var place = autocomplete[i].getPlace();
              if (!place.geometry) {
                return;
              }

              // If the place has a geometry, then present it on a map.
              if (place.geometry.viewport) {
                map.fitBounds(place.geometry.viewport);
              } else {
                map.setCenter(place.geometry.location);
                map.setZoom(17);  // Why 17? Because it looks good.
              }

              marker.setIcon(/** @type {google.maps.Icon} */({
                url: place.icon,

                scaledSize: new google.maps.Size(35, 35)

              marker.setPosition(place.geometry.location);
              marker.setVisible(true);

              var address = '';
              if (place.address_components) {
                address = [

                  (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);
              infowindow.open(map, marker);
            });
}
        function initialize() {
          var mapOptions = {
            center: new google.maps.LatLng(40.4700, 49.9600),
            zoom: 10,
            zoomControl:true,
            zoomControlOptions: {

            mapTypeControl:true,
            mapTypeControlOptions: {
              style:google.maps.MapTypeControlStyle.DROPDOWN_MENU 
            }
          };
          map = new google.maps.Map(document.getElementById('map-canvas'),
            mapOptions);
          var types = document.getElementById('type-selector');
          map.controls[google.maps.ControlPosition.TOP_LEFT].push(types);


          var inputs = document.getElementsByClassName("controlsInput");
          var autocomplete = [];
          for(var i = 0; i < inputs.length; i++) {  
           setupAutocomplete(autocomplete,inputs,i);
          }
          // Sets a listener on a radio button to change the filter type on Places
          // Autocomplete.
          function setupClickListener(id, types) {
            var radioButton = document.getElementById(id);
            google.maps.event.addDomListener(radioButton, 'click', function() {
              for (var i=0 ; i<autocomplete.length; i++) {
                autocomplete[i].setTypes(types);
              }
            });
          }

          setupClickListener('changetype-all', []);
          setupClickListener('changetype-establishment', ['establishment']);
          setupClickListener('changetype-geocode', ['geocode']);
        }

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

        </script>

为什么只有最后一个输入的标记出现在Google商家信息自动填充功能中？
