javascript - Google Maps V3 API 链接到 infowindow

转载作者：行者123 更新时间：2023-12-03 12:07:06

我正在开发 google map API v3(使用 php 和 mysql)，并且正在寻找从链接打开信息窗口的解决方案。

说明:

我创建了一个带有一些标记(客户)的谷歌地图，并直接从我的数据库在另一个循环中创建了一个列表，我希望能够单击我的客户的名字来打开 map 上的信息窗口。

感谢@MrUpsidown，我找到了这段代码并对其进行了修改，但它不起作用。

客户页面:

<div>
    <? include('phpsqlajax_map_v5.php');?>
</div>
<div>
    <?
        $reponseENT = $bdd->query('
        SELECT *
        FROM client
        WHERE adresse !=""
        AND archive = "FAUX"
        ');
        while($repE = $reponseENT->fetchObject())
            {
            ?>  
                <p><a><? echo $repE->Nom." ".$repE->departement;?></a></p>
            <?
            }
    ?>
</div>

这里是myphpsqlajax_map_v5.php(测试用的自定义名称)

<script type="text/javascript">
//<![CDATA[
var markers = [];


function load() {
  var map = new google.maps.Map(document.getElementById("map"), {
    center: new google.maps.LatLng(46.70, 2.00),
    zoom: 6,
    mapTypeId: 'roadmap'
  });
    var marker, i;

    var infoWindow = new google.maps.InfoWindow;

  // Change this depending on the name of your PHP file
    downloadUrl("gen_map_xml2.php",function(data){
    var xml = data.responseXML;
    var markers = xml.documentElement.getElementsByTagName("marker");
    for (var i = 0; i < markers.length; i++) {
      var name = markers[i].getAttribute("name");
      var address = markers[i].getAttribute("address");
      var type = markers[i].getAttribute("type");
      var nument = markers[i].getAttribute("nument");
      var point = new google.maps.LatLng(
          parseFloat(markers[i].getAttribute("lat")),
          parseFloat(markers[i].getAttribute("lng")));
      var html = "<b><a href='reporting_client.php?client=" + nument + "'>" + name +"</a></b><br/>" + address;
      var icon = customIcons[type] || {};
      var marker = new google.maps.Marker({
        map: map,
        position: point,
        icon: icon.icon
      });
      bindInfoWindow(marker, map, infoWindow, html);
    }
  });
}

function bindInfoWindow(marker, i,map, infoWindow, html) {
  google.maps.event.addListener(marker, 'click', function(marker, i) {
    infoWindow.setContent(html);
    infoWindow.open(map, marker);
  } 
    (marker, i));

        // Push the marker to the 'markers' array
        markers.push(marker);
    }

}
google.maps.event.addDomListener(window, 'load', initialize);

// The function to trigger the marker click, 'id' is the reference index to the 'markers' array.
function myClick(id){
    google.maps.event.trigger(markers[id], 'click');
});
}

function downloadUrl(url, callback) {
  var request = window.ActiveXObject ?
      new ActiveXObject('Microsoft.XMLHTTP') :
      new XMLHttpRequest;

  request.onreadystatechange = function() {
    if (request.readyState == 4) {
      request.onreadystatechange = doNothing;
      callback(request, request.status);
    }
  };

  request.open('GET', url, true);
  request.send(null);
}

function doNothing() {}

//]]>
</script>                       


<body onload="load()">
<div id="map" style="width: 100%; height: 550px;display:block;"></div>
</body>

然后，这是我的 gen_map-xml2.php

<?php
require("inc/header.php");

function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','&lt;',$htmlStr);
$xmlStr=str_replace('>','&gt;',$xmlStr);
$xmlStr=str_replace('"','&quot;',$xmlStr);
$xmlStr=str_replace("'",'&#39;',$xmlStr);
$xmlStr=str_replace("&",'&amp;',$xmlStr);
$xmlStr=str_replace("é",'&eacute;',$xmlStr);
$xmlStr=str_replace("è",'&egrave;',$xmlStr);
$xmlStr=str_replace("à",'&agrave;',$xmlStr);
return $xmlStr;
}

// Connexion à la base de données
$connection=mysql_connect ($host, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}

// Vérification de la connexion
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}

// Commande sql de sélection
$query = "
SELECT * 
FROM markers 
WHERE 1
";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}

header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';

// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'nument="' . $row['nument'] . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
}

// End XML file
echo '</markers>';

?>

你能帮我吗？

最佳答案

成功!我创建了一个包含所有位置的 php 文件，并创建了一个具有相同条件的循环来进行精确的监听

<?php
require("inc/header.php");

$fichier ="location.php";
$ouverture = fopen($fichier, "r" );
$ecriture = fopen($fichier, "w+" );

$reponse = $bdd->query('
SELECT * 
FROM client
WHERE 1
ORDER BY nom
');
while ($donnees = $reponse->fetch())
    {
    $id = $donnees['nument'];
    $rsent = preg_replace("/'/","\'",$donnees['nom']);
    $adresse = preg_replace("/'/","\'",$donnees['adresse']);
    $lat = $donnees['lat'];
    $lng = $donnees['lng'];
    $type = $donnees['type'];
    $location= "
        ['<a href=\"reporting_client.php?client=".$id."\">".$rsent."</a>                
        <br/>".$adresse."', ".$lat.", ".$lng."],\n
        ";
        fwrite($ecriture,$location);
    }
fclose($ouverture);
fclose($ecriture);
?>
