我希望能够在基于网络的Google地图上绘制路线。我花了很多时间查看Google Maps API,并编写了以下Javascript:
$(document).ready(function () {
$(function() {
loadScript();
});
});
function initialize() {
var myOptions = {
zoom: 10,
disableDefaultUI: true,
center: new google.maps.LatLng(51.5001524, -0.1262362),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('fullscreen'), myOptions);
var ck = Math.floor(Math.random() * 1000);
var ctaLayer = new google.maps.KmlLayer('http://xxx/storage/kml/test.kml');
ctaLayer.setMap(map);
}
function loadScript() {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize';
document.body.appendChild(script);
}
我的.kml
文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<Style id="blueLine">
<LineStyle>
<color>ffff0000</color>
<width>4</width>
</LineStyle>
</Style>
<Style id="pinkLine">

<width>4</width>
</LineStyle>
</Style>
<Placemark>
<name>LHR-BSS</name>
<visibility>1</visibility>
<styleUrl>#blueLine</styleUrl>
<description><![CDATA[LHR-BSS]]></description>
<LineString>
<extrude>1</extrude>
<tessellate>1</tessellate>
<coordinates>

4.4895353,50.9035504,0
</coordinates>
</LineString>
</Placemark>
</Document>
</kml>
尽管如此,我还是无法在Google地图中绘制第二行。当我在Google地球中加载KML时,它没有加载任何问题。我做错了什么?
答案 0 :(得分:0)
这比我想象的容易得多。我不需要KML或KML层(因为缓存btw而臭名昭着)。我只是用过:
var p = new google.maps.Polyline({
map: m.map,
path: [hkg, end],
strokeColor: color,
geodesic: m.geodesic
});
确保在设置地图时,geodesic设置为true:
var maps = {
mymap: {
map: null,
geodesic: true,
overlay: { path: null} }
};
将lat long设置为google lat longs:
var hkg = new google.maps.LatLng(22.3088856, 113.9141464); /*hong kong*/
这是一种享受:)
