[英]Google Maps API: Geocoder: unknown property function:
我目前正在嘗試使用Google Geocoder API將地址轉換為緯度/經度坐標,但是,在其開發人員文檔( https://developers.google.com/maps/documentation/javascript/geocoding )上使用示例時,我遇到錯誤“ InvalidValueError:未知屬性函數”
在我的HTML文件中,我調用了Google Map API和一個Map div,應在其中渲染我的地圖。 (當然,我也有其他內容,但是僅出於直截了當的目的,我只會發布相關代碼)
<script src="https://maps.googleapis.com/maps/api/js?key=APIKEY&callback=initMap" async defer></script>
<div id="map"></div>
在我的JS文件中:
window.initMap = function(){
var fromLocation = new google.maps.LatLng(37.09024, -95.712891),
destLocation = new google.maps.LatLng(37.09024, -95.712891),
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 37.09024 , lng: -95.712891}, // center of USA
zoom: 4 // continet level
}),
directionService = new google.maps.DirectionsService(),
directionRender = new google.maps.DirectionsRenderer({
map: map
}),
markerA = new google.maps.Marker({
position: fromLocation,
title: "Point A",
label: "From",
map:map
}),
markerB = new google.maps.Marker({
position: destLocation,
title: "Point B",
label:"Destination",
map:map
});
getLatLng("Los Angeles");
} // end of initMap
function getLatLng(address){
geocoder = new google.maps.Geocoder();
geocoder.geocode({address: address, function(results,status){
if(status === 'OK'){
console.log(results[0].geometry.location);
}
else{
console.log("Geocoding couldn't convert string address to lat/long points");
}
}
});// end of geocoder method.
}
關於如何修復未知屬性函數錯誤的任何想法? 謝謝!
您在getLatLng
函數中有一個錯字:
geocoder.geocode({
address: address,
address: address
后必須有一個“}” address: address
function getLatLng(address) {
geocoder = new google.maps.Geocoder();
geocoder.geocode({
address: address},
function(results, status) {
if (status === 'OK') {
console.log(results[0].geometry.location);
} else {
console.log("Geocoding couldn't convert string address to lat/long points");
}
}); // end of geocoder method.
}
window.initMap = function() { var fromLocation = new google.maps.LatLng(37.09024, -95.712891), destLocation = new google.maps.LatLng(37.09024, -95.712891), map = new google.maps.Map(document.getElementById('map'), { center: { lat: 37.09024, lng: -95.712891 }, // center of USA zoom: 4 // continet level }), directionService = new google.maps.DirectionsService(), directionRender = new google.maps.DirectionsRenderer({ map: map }), markerA = new google.maps.Marker({ position: fromLocation, title: "Point A", label: "From", map: map }), markerB = new google.maps.Marker({ position: destLocation, title: "Point B", label: "Destination", map: map }); getLatLng("Los Angeles"); } // end of initMap function getLatLng(address) { geocoder = new google.maps.Geocoder(); geocoder.geocode({ address: address }, function(results, status) { if (status === 'OK') { console.log(results[0].geometry.location); } else { console.log("Geocoding couldn't convert string address to lat/long points"); } }); // end of geocoder method. }
html, body, #map { height: 100%; width: 100%; margin: 0px; padding: 0px }
