我尝试为我当前的位置和标记坐标制定方向。所以我使用getcurrentposition得到纬度和经度。然后,我标记它。
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var node = new google.maps.LatLng(-7.276442,112.791174);
var mapOptions = {
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
directionsDisplay.setMap(map);
navigator.geolocation.getCurrentPosition(function(position) {
pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var marker = new google.maps.Marker({
position : pos,
map: map,
title:'Lokasi Anda'
});
var marker1 = new google.maps.Marker({
position : node,
map: map,
title:'Lokasi Anda'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
}
然后,我使用这个函数计算它。
function calcRoute() {
var request = {
origin:pos,
destination:node,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
但为什么我看不到从pos
to 的方向node
。有什么建议吗?
