[英]How to get coordinates of a place using google map javascript api
问题描述
I have a address, i want to display it on the map and also get the lat/lng
我有一个地址，我想在 map 上显示它并获取 lat/lng
<body> <div id="floating-panel"> <input id="address" type="textbox" value="Sydney, NSW"> <input id="submit" type="button" value="Geocode"> </div> <div id="map"></div> <script> function initMap() { var map = new google.maps.Map(document.getElementById('map'), { zoom: 8, center: {lat: -34.397, lng: 150.644} }); var geocoder = new google.maps.Geocoder(); document.getElementById('submit').addEventListener('click', function() { geocodeAddress(geocoder, map); }); } function geocodeAddress(geocoder, resultsMap) { var address = document.getElementById('address').value; geocoder.geocode({'address': address}, function(results, status) { if (status === 'OK') { resultsMap.setCenter(results[0].geometry.location); ////////////////////////////////////////// console.log(results[0].geometry.location); ////////////////////////////////////////// var marker = new google.maps.Marker({ map: resultsMap, position: results[0].geometry.location }); } else { alert('Geocode was not successful for the following reason: ' + status); } }); } </script> <script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"> </script> </body> I got this:我懂了：
the map works fine but i can't get the lng/lat. map 工作正常，但我无法获得 lng/lat。
How can i get that using the Maps JavaScript API or i have to use other map API like Geocoding API How can i get that using the Maps JavaScript API or i have to use other map API like Geocoding API

As you can see from your own screenshot, in order to retrieve the calculated values of lat/long, you need to treat those attributes like functions.正如您从自己的屏幕截图中看到的那样，为了检索 lat/long 的计算值，您需要将这些属性视为函数。
let latVal = results[0].geometry.location.lat();
let lngVal = results[0].geometry.location.lng();
