有幾個問題。
我收到 JavaScript 錯誤：InvalidValueError: setCenter: not a LatLng or LatLngLiteral with finite coordinates: in property lat: NaN is not an accepted value因為在您的 API 中包括：
你有callback=initMap，但你不希望它在 API 加載時運行，你希望它在用戶單擊“查找地址”后運行。刪除：
<script src="https://maps.googleapis.com/maps/api/js?key=REMOVED_FOR_PRIVACY" async defer></script>
我收到 JavaScript 錯誤：Uncaught TypeError: Cannot read property 'geometry' of undefined當我單擊“查找地址”時，因為沒有錯誤檢查。如果我檢查文本狀態（至少使用 Google 測試鍵），它會告訴我："API keys with referer restrictions cannot be used with this API.", status: "REQUEST_DENIED". 如果我對地理編碼器的請求使用不受限制的密鑰，我會得到一個帶有標記的地圖（至少對于有效地址）。我建議使用 Google JavaScript API v3 Geocoder，并添加錯誤檢查：
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
address: addressClean + "," + postcodeClean
}, function(results, status) {
console.log(status);
if (status == 'OK') {
console.log(results);
longitude = results[0].geometry.location.lng();
latitude = results[0].geometry.location.lat();
document.getElementById("long").value = longitude;
document.getElementById("lat").value = latitude;
// geocoder is asynchronous, do this in the callback function
longitude = $("input#long").val();
latitude = $("input#lat").val();
if (longitude && latitude) {
longitude = parseFloat(longitude);
latitude = parseFloat(latitude);
initMap(longitude, latitude);
}
} else alert("geocode failed")
});
代碼片段：
var apiKey = 'AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk';
var longitude, latitude, map;
jQuery(document).ready(function($) {
$('#find-address').click(function() {
var address = $('#address').val();
var postcode = $('#postcode').val();
var addressClean = address.replace(/\s+/g, '+');
var postcodeClean = postcode.replace(/\s+/g, '+');
var apiCall = 'https://maps.googleapis.com/maps/api/geocode/json?address=' + addressClean + ',+' + postcodeClean + '&key=' + apiKey + '';
//$.getJSON(apiCall,function (data, textStatus) {
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
address: addressClean + "," + postcodeClean
}, function(results, status) {
console.log(status);
if (status == 'OK') {
console.log(results);
longitude = results[0].geometry.location.lng();
latitude = results[0].geometry.location.lat();
document.getElementById("long").value = longitude;
document.getElementById("lat").value = latitude;
// geocoder is asynchronous, do this in the callback function
longitude = $("input#long").val();
latitude = $("input#lat").val();
if (longitude && latitude) {
longitude = parseFloat(longitude);
latitude = parseFloat(latitude);
initMap(longitude, latitude);
}
} else alert("geocode failed")
});
});
function initMap(longitude, latitude) {
var myLatlng = new google.maps.LatLng(latitude, longitude);
var mapOptions = {
zoom: 12,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById("map-embed-div"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
draggable: true,
title: "Where's your garden?"
});
};
})
