我编写了一个代码，用于从数据库中获取纬度和经度值并将其显示在地图中。

此代码适用于 Linux（Ubuntu），但当我在 Windows 中运行时它不显示 Google 地图。请帮助我找到解决方案。

查看源信息：

   <?
     $dbname            ='test'; //Name of the database
     $dbuser            =''; //Username for the db
     $dbpass            =''; //Password for the db
     $dbserver          ='localhost'; //Name of the mysql server

     $dbcnx = mysql_connect ("$dbserver", "$dbuser", "$dbpass");
     mysql_select_db("$dbname") or die(mysql_error());
     ?>
     <html>
     <head>
     <meta http-equiv="content-type" content="text/html; charset=utf-8"/>
     <style type="text/css">
      body { font: normal 10pt Helvetica, Arial; }
     #map { width: 350px; height: 300px; border: 0px; padding: 0px; }
     </style>
     <script src="http://maps.google.com/maps/api/js?v=3&sensor=false"    type="text/javascript"></script>
     <script type="text/javascript">

     var icon = new google.maps.MarkerImage("http://maps.google.com/mapfiles/ms/micons/blue.png",
     new google.maps.Size(32, 32), new google.maps.Point(0, 0),
     new google.maps.Point(16, 32));
     var center = null;
      var map = null;
     var currentPopup;
     var bounds = new google.maps.LatLngBounds();
     function addMarker(lat, lng, info) {
     var pt = new google.maps.LatLng(lat, lng);
     bounds.extend(pt);
     var marker = new google.maps.Marker({
     position: pt,
     icon: icon,
     map: map
     });
    var popup = new google.maps.InfoWindow({
    content: info,
    maxWidth: 300
    });

   google.maps.event.addListener(marker, "click", function() {
   if (currentPopup != null) {
   currentPopup.close();
   currentPopup = null;
   }
    popup.open(map, marker);
    currentPopup = popup;
    });
    google.maps.event.addListener(popup, "closeclick", function() {
   map.panTo(center);
     currentPopup = null;
   });
     }
   function initMap() {
   map = new google.maps.Map(document.getElementById("map"), {
    center: new google.maps.LatLng(0, 0),
    zoom: 14,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
    mapTypeControl: false,
    mapTypeControlOptions: {
   style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR
     },
    navigationControl: true,
    navigationControlOptions: {
   style: google.maps.NavigationControlStyle.SMALL
   }
   });



   <?
   $query = mysql_query("SELECT * FROM manu");
   while ($row = mysql_fetch_array($query)){

   $lat=$row['lat'];
   $lon=$row['lon'];

  echo ("addMarker($lat, $lon);\n");
   }
  ?>
  center = bounds.getCenter();
  map.fitBounds(bounds);

只是回应 addMarkers(... 不会调用它。

将这些函数调用包装在 $(document).ready()

http://docs.jquery.com/Tutorials:Introducing_$(document).ready()

$(document).ready(function() {
<?
  $query = mysql_query("SELECT * FROM manu");
  while ($row = mysql_fetch_array($query)){
    $name=$row['name'];
    $lat=$row['lat'];
    $lon=$row['lon'];
    $desc=$row['desc'];
    echo ("addMarker($lat, $lon,'<b>$name</b><br/>$desc');\n");
  }
  ?>
  center = bounds.getCenter();
  map.fitBounds(bounds);
});
