如何循环显示来自跟踪路由输出的谷歌地图v3中的标记 - how to looping to display markers in google maps v3 from traceroute output

我是php mysql和google maps v3的新手。我在谷歌地图v3中遇到了问题。我制作了基于网络的跟踪路由，并在谷歌地图v3中映射了跟踪路由的结果，用于我大学教育的最后一个项目。我尝试了很多教程，但没有奏效。我也尝试了这个论坛中的教程，但没有任何效果。所以我的问题是我无法显示我从数据库中获取位置数据的多个标记。也许是因为我是新手，不知道该怎么做。我也混淆了循环以显示标记。所以这是php代码：

<?php
error_reporting(E_ALL ^ (E_NOTICE));
ini_set('max_execution_time', 360);
$enable_log_user = FALSE;
global $ip, $host_name,  $host_ip, $output, $integer;
$host  = @$_POST['host']; 
$trace = @$_POST['trace'];
$self  = $_SERVER['PHP_SELF'];
include("phpsqlajax_dbinfo.php");
$connection = mysql_connect ('127.0.0.1', $username, $password);
if (!$connection) {  die('Not connected : ' . mysql_error());} 
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can''t use db : ' . mysql_error());
} 
function get_ip()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$ip = get_ip(); 
?>

好吧，如果你们读了我的代码，我真的很抱歉。看起来一团糟。因为我不知道如何很好地显示代码。我想得到帮助的最重要的事情是地图。了解如何显示所有标记。尤其是循环。谷歌地图没有显示标记。它仅显示地图。所以对于所有读过这个问题的大师。我只是需要你的帮助尽快。如果我的英语不好，我真的很抱歉，我对你们的错误。

问题是你没有给你的标记任何位置：

 var point = [];
 var icon = pinImage;
 var marker = new google.maps.Marker({
    map: map,
    position: point,
    icon: pinImage,
    shadow: pinShadow
    });

因此，您所做的只是将仓位创建为空数组。你需要在那里为这个位置创建一个 LatLng（）。

所以现在你有一系列要点：

 var point = [new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574)];
 var icon = pinImage;
 var marker = new google.maps.Marker({
    map: map,
    position: point,
    icon: pinImage,
    shadow: pinShadow
    });
    marker.setMap(map);

您需要做的是遍历数组，为每个数组创建一个标记：

var point = [new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574)];
var icon = pinImage;
for (var i = 0; i < point.length; i++) {
     var marker = new google.maps.Marker({
        map: map,
        position: point[i],
        icon: pinImage,
        shadow: pinShadow
        });
}

此外，setMap 行是多余的，因为当你说 map：map 时，这就是你需要做的。
