javascript - 谷歌地图中的多个标记

转载作者：搜寻专家更新时间：2023-10-31 21:11:08

我在谷歌地图中放置多个标记时遇到问题。这是我的代码。它在页面重新加载期间只显示一个标记，当页面完全加载时 map 不显示。
javascript代码:

<head>
<script src="http://maps.googleapis.com/maps/api/js?key=AIzaSyDY0kkJiTPVd2U7aTOAwhc9ySH6oHxOIYM&sensor=false">
</script>
<script>
function initialize(lat,lon)
{
  var myCenter=new google.maps.LatLng(lat,lon);
  var mapProp = {
  center:myCenter,
  zoom:9,
  mapTypeId:google.maps.MapTypeId.ROADMAP
  };

 var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);

 var marker=new google.maps.Marker({
  position:myCenter,
 });
marker.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);
 </script>
</head>
<body>
<div id="googleMap" style="width:500px;height:380px;"></div>
</body>
</html>

php代码:

<?php
require_once 'geocode.php';

$addarray=array(0=>'a, ahmedabad,india',1=>'b,ahmedabad,india');
foreach($addarray as $add)
{
// define the address and set sensor to false
$opt = array (
    'address' => urlencode($add),
    'sensor'  => 'false'
);

// now simply call the function
$result = getLatLng($opt);

// if status was successful, then print the lat/lon ?
if ($result['status']) {

   echo '<pre>';
?>
 <script>
initialize(<?php echo $result['lat'];?>,<?php echo $result['lon'];?>);
 </script>  

<?php
   echo '</pre>';
}
}
?>

这里我首先根据地址得到了纬度和经度，然后我调用了 javascript 函数来放置标记。但是有些东西丢失了或者造成了问题。
提前致谢。

最佳答案

感谢@Tudor Ravoiu 的帮助。它通过改变一些东西来解决。
我已经在 php 中创建了 json 格式的数组并将其传递给 javascript。

<?php
require_once 'geocode.php';

$addarray=array(0=>'a,ahmedabad,india',1=>'b,ahmedabad,india',2=>'c,ahmedabad,india');
$lat1=array();
foreach($addarray as $add)
{
// define the address and set sensor to false
$opt = array (
    'address' => urlencode($add),
    'sensor'  => 'false'
);

// now simply call the function
$result = getLatLng($opt);

// if status was successful, then print the lat/lon ?
if ($result['status'])
{ 
   array_push($lat1,array($result['address'],$result['lat'],$result['lon']));
}
}echo json_encode($lat1);
?>

javascript代码:

<script type="text/javascript">
var locations = <?php echo json_encode($lat1);?>;
var map = new google.maps.Map(document.getElementById('map'), {
  zoom: 10,
  center: new google.maps.LatLng(23.0171240, 72.5330533),
  mapTypeId: google.maps.MapTypeId.TERRAIN
});

var infowindow = new google.maps.InfoWindow();

var marker, i;
for (i = 0; i < locations.length; i++) 
{ 
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
   });

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}
