有没有办法做到这一点?
就像,我的数据库中有一些数据,我在googlemap api中将此数据显示为标记。
但我想从我的数据库中的相同ID更改标记图像。
名称和描述,按标记正确显示,但我想更改标记图像
我的代码:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title></title>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="http://maps.google.com/maps/api/js?v=3&sensor=false" type="text/javascript"></script>
<script type="text/javascript">
var icon = new google.maps.MarkerImage('http://localhost/partytime/uploadedimages/davi.png',
new google.maps.Size(50,50),
new google.maps.Point(0,0),
new google.maps.Point(0,0),
new google.maps.Size(50,50));
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: 3,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR
},
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
}
});
<?php
}
$query = mysql_query("SELECT * FROM localizacoes");
while ($row = mysql_fetch_array($query)){
$r = explode( ',', $row['posicao'] );
$name=$row['nome'];
$lat = $r[0];
$lon = $r[1];
$dataevento = explode( '-', $row['dataevento'] );
$ano = $dataevento[0];
$mes = $dataevento[1];
$dia = $dataevento[2];
echo ("addMarker($lat, $lon,'<h1><b>$name</b></h1>$dia-$mes-$ano');\n");
}
?>
}
</script>
</head>
<body onload="initMap()" style="margin:0px; border:0px; padding:0px;">
<div id="centro">
<div id="map">
</div>
</div>
</html>
注意:在这段代码中,我从localhost中输入了一个imagem ...这个imagem引用了一个ID,我希望将每个id中的每个图像显示为googlemap marker icon

有关如何将标记图标与数据库中的类型字段相关联的信息,请参阅此文章:Using PHP/MySQL with Google Maps: Custom Icons。
从那篇文章:
自定义图标
您可以为标记指定自定义图标。
首先创建一个关联数组,将您的图标与您的类型字符串相关联:&#39; restaurant&#39;或者&#39; bar。&#39;这使得稍后在从XML创建标记时可以轻松引用图标。
var customIcons = {
restaurant: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png'
},
bar: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png'
}
};
