我需要谷歌地图的帮助

我想要没有刷新地图更改标记

我从mysql获取数据并创建标记

我的档案:

  

     function initialize(){

     

var latlng = new google.maps.LatLng(55.472627,23.15918);

     

var geocoder;      var map;      var markersArray = [];      var infos = [];

     

var myOptions = {           zoom:8,           中心:latlng,            mapTypeId:google.maps.MapTypeId.ROADMAP      };

     

var map = new google.maps.Map(document.getElementById(“map_canvas”),myOptions);

     

var encodedString;      var stringArray = [];

     

encodedString = document.getElementById(“encodedString”)。value;      stringArray = encodedString.split(“ * *”);

     

var x;      for(x = 0; x< stringArray.length; x = x + 1){

     

var addressDetails = [];

     

addressDetails = stringArray [x] .split(“,”);

     

var lat = new google.maps.LatLng(addressDetails [0],addressDetails [1]);      的console.log(LAT);
     console.log(addressDetails [0],addressDetails [1]);

var marker = new google.maps.Marker({
map: map,
position: lat,
icon: addressDetails[2],
title: "Atnaujinta: "+addressDetails[3]+""

            });
      }
    }setInterval('updateMap()', 10000);
        </script>

    </head>
    <?php 
    //get data form mysql
    mysql_connect('localhost', 'adena_root', 'gintariukas1');
    mysql_select_db('adena_nav');

    $encodedString = "";
    $x = 0;

    $mysql = mysql_query("SELECT X,Y,marker,data FROM nav");

    while ($row = mysql_fetch_array($mysql, MYSQL_NUM)){
        if ( $x == 0 ){
             $separator = "";
        }else{
          $separator = "****";
        }

      $encodedString = $encodedString.$separator.
        "".$row[0].
        ",".$row[1].
        ",".$row[2].
      ",".$row[3];
        $x = $x + 1;


    }
    ?>
    <body onload="initialize()">
    <input type="hidden" id="encodedString" name="encodedString" value="<?php echo $encodedString; ?>" />

    <div id="map_canvas"></div>
    </body>
    </html>

也许有人知道?:)

您可以使用AJAX执行此操作。首先创建一个单独的页面,它将以JSON格式显示您的地图数据,然后在JavaScript中获取它们以将它们显示到地图中。这是一个很好的教程,虽然它使用谷歌地图v2,你可以简单地将它们更改为v3代码。
