我想创建一个链接,打开一个新的Google地图标签,其中包含从navigator.geolocation.getCurrentPosition
到特定placeId
的路线。
如果地理位置存在问题,请打开一个新选项卡,但不完成原点 这是我尝试的:
const options = {
placeId: 'ChIJDyx4bNhu5kcRqJ3RkAPGMEk',
latitude: 48.925606,
longitude: 2.327621,
};
const mapOptions = {
zoom: 15,
center: new google.maps.LatLng(options.latitude, options.longitude),
};
const map = new google.maps.Map(document.getElementById('Map'), mapOptions);
const service = new google.maps.places.PlacesService(map);
service.getDetails({
placeId: options.placeId,
}, (result, status) => {
if (status !== google.maps.places.PlacesServiceStatus.OK) {
alert(status);
return;
}
const marker = new google.maps.Marker({
map: map,
position: result.geometry.location,
});
});
$('.js-ItinaryFromI').on('click', () => {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition((position) => {
const pos = {
lat: position.coords.latitude,
lng: position.coords.longitude,
};
}, () => {
// The problem seems to come from this line :
window.open(`https://www.google.com/maps/dir/origin=pos&destination=place_id:${options.placeId}&travelmode=driving`, '_blank');
});
} else {
// And this line
window.open(`https://www.google.com/maps/dir//place_id${options.placeId}&travelmode=driving`, '_blank');
}
});
请问好吗?

如果您想计算位置之间的路线,则应使用 Google Maps Directions API 。您可以搜索多种交通方式的路线,包括公交,驾车,步行或骑车。
这些参数(来源,目的地,travel_mode)在Google Maps Directions API中使用,可能无法使用Google地图。
我还注意到,在您提供的代码中,某些变量未正确连接到请求中。因此,您的请求无法提供准确的结果。
以下是有效请求的示例:
window.open('https://maps.googleapis.com/maps/api/directions/json?origin='+pos.lat+','+pos.lng+'&destination=place_id:'+options.placeId+'&travelmode=driving&key=YOUR_API_KEY', '_blank');
不要忘记在每个请求中加入 API key 。
我修改了你的代码。您可以在下面查看:
const options = {
placeId: 'ChIJDyx4bNhu5kcRqJ3RkAPGMEk',
//placeId: 'ChIJ51Ic7BXIlzMRK2WH8qoM6Ek',
latitude: 48.925606,
longitude: 2.327621,
};
function initMap() {
const mapOptions = {
zoom: 15,
center: new google.maps.LatLng(options.latitude, options.longitude),
};
const map = new google.maps.Map(document.getElementById('Map'), mapOptions);
const service = new google.maps.places.PlacesService(map);
service.getDetails({
placeId: options.placeId,
}, (result, status) => {
if (status !== google.maps.places.PlacesServiceStatus.OK) {
alert(status);
return;
}
const marker = new google.maps.Marker({
map: map,
position: result.geometry.location,
});
});
if ( navigator.geolocation ) {
navigator.geolocation.getCurrentPosition((position) => {
const pos = {
lat: position.coords.latitude,
lng: position.coords.longitude,
};
document.getElementById('js-ItinaryFromI').addEventListener('click', () => {
window.open('https://maps.googleapis.com/maps/api/directions/json?origin='+pos.lat+','+pos.lng+'&destination=place_id:'+options.placeId+'&travelmode=driving&key=[API-KEY]', '_blank');
});
});
} else {
alert('Geolocation not found!');
}
}
html,body,#Map {
width:100%;
height:100%;
}
<button id="js-ItinaryFromI">Click Me</button>
<div id="Map" ></div>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCzjs-bUR6iIl8yGLr60p6-zbdFtRpuXTQ&callback=initMap&libraries=places">
</script>
您可以使用 JSBin 尝试此操作。由于某种原因,它在Stackoverflow的代码片段中不起作用。我不知道为什么。
祝你好运,编码愉快!
