                            contentString = '<div id="content">' +

                      infowindow = new google.maps.InfoWindow({
                             

                       content: contentString
                          

});

                         



 google.maps.event.addListener(marker, 'mouseover', (function (marker, i) {
                            


  return function () {
                            

      infowindow.open(map, marker);

                         

                  }
                          })(marker, i));
                        

  google.maps.event.addListener(marker, 'mouseout', (function (marker, i) {
                            


  return function () {
                            


      infowindow.close();
                         

     }
                         

 })(marker, i));
                

  })
               

 }  

     </script>
</div>

这是我的搜索内容代码。通过数据库，当警报 = 0 时，谷歌地图上不会显示任何脉冲。当 alert=1 时，Google Map 上会显示一个脉冲动画。

但我想在 ajax 的帮助下显示脉冲动画。
