我知道很多线程都在讨论这个问题,但我的代码仍然无效。 我正在使用google放置searchBox API。
我的代码:
function initMap(){
var map = new google.maps.Map(document.getElementById('peta'), {
center: {lat: -34.397, lng: 150.644},
zoom: 16
});
var infoWindow = new google.maps.InfoWindow({map: map});
// Try HTML5 geolocation.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
infoWindow.setPosition(pos);
infoWindow.setContent('Your Location.');
map.setCenter(pos);
}, function() {
handleLocationError(true, infoWindow, map.getCenter());
});
} else {
// Browser doesn't support Geolocation
handleLocationError(false, infoWindow, map.getCenter());
}
var input = document.getElementById('alamat');
var searchBox = new google.maps.places.SearchBox(input);
// Bias the SearchBox results towards current map's viewport.
map.addListener('bounds_changed', function() {
searchBox.setBounds(map.getBounds());
});
var markers = [];
// Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener('places_changed', function() {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
// Clear out the old markers.
markers.forEach(function(marker) {
marker.setMap(null);
});
markers = [];
// For each place, get the icon, name and location.
var bounds = new google.maps.LatLngBounds();
places.forEach(function(place) {
var icon = {
url: place.icon,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(25, 25)
};
// Create a marker for each place.
markers.push(new google.maps.Marker({
map: map,
icon: icon,
title: place.name,
position: place.geometry.location
}));
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
map.fitBounds(bounds);
document.getElementById('x').innerHTML(places.geometry.location.lat());
});
}

我将document.getElementById
放在我的文本框中,但它仍然没有显示纬度。我应该把这段代码放在哪里?
在其他主题中:
var location= places.geometry.location;
var lat = location.lat();
但它也不行。如果我重复这个问题,我很抱歉。谢谢。

你的元素#x是输入文本框吗?
若是,请尝试:
document.getElementById('x').value = places.geometry.location.lat();
这会将纬度添加到输入文本框的值。
这是你想要实现的目标吗?

我已经解决了这个问题。
@Dammeul说,我放了
document.getElementById('x').value = place.geometry.location.lat();
<{1>} places.forEach(function (place))
内
希望这有用。

它将地址转换为纬度和经度,并使用标记在地图上显示地址。您只需添加地图API密钥

您好,我尝试了一下,而且效果很好,我已经很久了,我正在使用react + searchboxAPI,请随时跟进,这里是文档,我意识到您不能做x [“ geometry”] [“ location”]。lat(),相反,您需要遍历返回的每个地方,以对其进行测试,我做了 console.log(x [0] [“ geometry”] [“ location”]。lat())仅用于获取第一个结果。您可以使用js map函数或使用for循环遍历20个数组。欢呼
