我正在尝试将坐标捕捉到最近的道路。但我仍然不能以简单的方式做到这一点。这是简单的代码,如何改进它,结果将成为路上的标记:

<!DOCTYPE html>
<html>
<head>
<title>Map</title>

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 300px; width:600px }
</style>

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>

<script type="text/javascript">
function initialize() {
var homeLatlng = new google.maps.LatLng(24.696554,-81.328238);

var myOptions = {
zoom: 15,
center: homeLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};

var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

var image = new google.maps.MarkerImage(
'http://maps.google.com/mapfiles/ms/micons/green-dot.png',
new google.maps.Size(32, 32), // size
new google.maps.Point(0,0), // origin
new google.maps.Point(16, 32) // anchor
);

var shadow = new google.maps.MarkerImage(
'http://maps.google.com/mapfiles/ms/micons/msmarker.shadow.png',
new google.maps.Size(59, 32), // size
new google.maps.Point(0,0), // origin
new google.maps.Point(16, 32) // anchor
);

var homeMarker = new google.maps.Marker({
position: homeLatlng,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
}

google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map_canvas"></div>
</body>
</html>

我想知道最简单的方法。感谢您的帮助。

最佳答案

使用路线服务。获取从兴趣点到兴趣点的行车路线。应该在路上。

var directionsService = new google.maps.DirectionsService();

directionsService.route({origin:homeLatlng, destination:homeLatlng, travelMode: google.maps.DirectionsTravelMode.DRIVING}, function(response, status) {
if (status == google.maps.DirectionsStatus.OK)
{
var homeMarker = new google.maps.Marker({
position: response.routes[0].legs[0].start_location,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
} else {
var homeMarker = new google.maps.Marker({
position: homeLatlng,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
}
});
