我正在使用 PHP 和 MYSQL 来从数据库中检索数据并在 Google Map API 上显示标记,并添加一个信息窗口,其中包含使用 click-Listener 从数据库中检索到的信息。 添加信息窗口后,它似乎不起作用。

我的错误在哪里?

代码:

<?php
/*
Template Name: MAP2
*/

get_header();
?>


<!DOCTYPE html>
<html>
<head>
<title>Custom Markers</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCquey2tCZ32jLJJDEEi2D7_RnXXyj9RTI&callback=initMap">
</script>
<style>
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 600px;
}
/* Optional: Makes the sample page fill the window. */
html, body {
height: 100%;
margin: 0;
padding: 0;
}
</style>

</head>
<body>
<div id="map">
<div class="map-popupstring hidden" id="popupstring1">
<div class="text-center">
<h3>title</h3>
<p>subinfo</p>
</div>
</div>

</div>

<script>

var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: new google.maps.LatLng(33.888630, 35.495480),
mapTypeId: 'roadmap'
});

var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
parking: {
icon: iconBase + 'parking_lot_maps.png'
},
library: {
icon: iconBase + 'library_maps.png'
},
info: {
icon: iconBase + 'info-i_maps.png'
}
};


var $popup = $("#popupstring1")

function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
//icon: icons[feature.type].icon,
data-popupstring-id: $popup,
map: map
});
}



var features = [
<?php
global $wpdb;
$prependStr ="";
foreach( $wpdb->get_results("SELECT siteID, latitude, longitude FROM site_coordinates2", OBJECT) as $key => $row) {
$latitude = $row->latitude;
$longitude = $row->longitude;
$info = $row->siteID;
echo $prependStr;
?>
{
position: new google.maps.LatLng(<?php echo $latitude; ?>, <?php echo $longitude; ?>),
type: '<?php echo $info; ?>'
}
<?php
$prependStr =",";
}
?>
];

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

for (var i = 0, feature; feature = features[i]; i++) {

addMarker(feature);
}
}



</script>


</body>
</html>

<?php
get_footer();
?>

最佳答案

           <div class="map-popupstring hidden" id="popupstring1">
<div class="text-center">
<h3>title</h3>
<p>subinfo</p>
</div>
</div>

您必须在 html 标签中放入想要的弹出窗口。和谷歌地图标签中的代码来初始化它。并使用 data-popupstring-id="#popupstring1" 标签在点击标记时对其进行初始化。

var $popup = $("#popupstring1")

function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
data-popupstring-id: $popup,
map: map
});
}
