Question

我有一个PHP代码，它从数据库（测试）和表名manu获取位置信息，这是使用wmy中的phpmyadmin创建的，并使用标记在地图上显示这些位置。意义纬度和经度值中的位置详细信息。

<?
$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 Page

body onload="initMap()" //you forget to close it.

div id="map"

在html文件中进行以下更改。

script src="http://maps.google.com/maps/api/js?v=3&sensor=false"    type="text/javascript"
script type="text/javascript" src="js/jquery.js"
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
        }
    });

// getjson code goes here which is as below because i was unable to format it here so i wrote it downward.

center = bounds.getCenter();
map.fitBounds(bounds);


}
/script>

    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;
    });
}

// getjson code goes here which is as below because i was unable to format it here so i wrote it downward. center = bounds.getCenter(); map.fitBounds(bounds);

我使用了，因此您需要创建一个$.getJSON('googlescript.php', function(items) { for (var i = 0; i < items.length; i++) { (function(item) { addMarker(item.lat, item.long, item.name + ' ' + item.desc); })(items[i]); } });文件并将代码粘贴到其中。 $.getJSON('googlescript.php',

googlescript.php

$query = mysql_query("SELECT * FROM manu")or die(mysql_error()); header('Content-Type: application/json'); $rows = array(); while ($row = mysql_fetch_array($query)) { $rows[] = $row; } echo json_encode($rows); exit;

现在检查一下，我确定你会得到你想要的结果。不要忘记更改jquery路径并更改数据库连接设置，请正确放置jquery路径。

使用php不会显示Google地图
