Question

我对使用Javascript的Google API方向有疑问，我是第一次使用它。

我正在开发一个拼车网站。我想在使用Google自动填充输入的两个地方之间创建一个方向。我设法获得了我作为字符串传递的两个LatLng坐标，以放入原点和目标字段。然而，由于NOT_FOUND＆＃34;它回应＆＃34;路线请求失败。谁能帮助我？谢谢:)）

HTML字段

<input type="text" name="departure"  id="autocomplete_address">
<input type="button" id="departure_check" value="Add this departure">

<input type="text" name="arrival"  id="autocomplete_address2">
<input type="button" id="arrival_check" value="Add this destination" >

使用Javascript：

var latorigine;
var latdestination;

function initMap() {
    var geocoder = new google.maps.Geocoder;
    var directionsService = new google.maps.DirectionsService;
    var directionsDisplay = new google.maps.DirectionsRenderer;
    map = new google.maps.Map(document.getElementById('searchmap'), {
        center: {lat: 50.437616, lng: 2.809546},
        zoom: 15
    });

    directionsDisplay.setMap(map);       

    //AUTOCOMPLETE
    var departure_input =(document.getElementById('autocomplete_address'));
    var arrival_input =(document.getElementById('autocomplete_address2'));
    var options = {
        types: ['address'],
        componentRestrictions: {country: "fr"}
    }
    var departure_autocomplete = new 
    google.maps.places.Autocomplete(departure_input,options);
    var arrival_autocomplete = new 
    google.maps.places.Autocomplete(arrival_input,options);

    document.getElementById('departure_check').addEventListener('click', function(latorigine) {
        var departure_place = departure_autocomplete.getPlace();
        latorigine = ' " '+ departure_place.geometry.location.lat() + ", " +  departure_place.geometry.location.lng()+ ' " ';
        console.log(latorigine);
    });

    document.getElementById('arrival_check').addEventListener('click', function(latdestination) {
        var arrival_place = arrival_autocomplete.getPlace();
        latdestination = ' " ' +arrival_place.geometry.location.lat() + ", " + arrival_place.geometry.location.lng()+ ' " ';
        console.log(latdestination);
    });

}
//END INITMAP


function trajectdirection(directionsService, directionsDisplay,latorigine, latdestination) {
    directionsService.route({
        origin: latorigine.toString(),
        destination: latdestination.toString(),
        travelMode: 'DRIVING'
        }, function(response, status) {
            if (status === 'OK') {
                directionsDisplay.setDirections(response);
            } else {
                window.alert('Directions request failed due to ' + status);
            }
        }
    });
}

Google Direction API错误（NOT_FOUND）
