}
});
Google Places API还提供REST API,包括Places自动完成。
但是从服务检索的数据必须用于地图。您可以使用下面的代码
<script src="http://maps.googleapis.com/maps/api/js?libraries=places" type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var place = autocomplete.getPlace();
document.getElementById('city2').value = place.name;
document.getElementById('cityLat').value = place.geometry.location.lat();
document.getElementById('cityLng').value = place.geometry.location.lng();
//alert("This function is working!");
//alert(place.name);
// alert(place.address_components[0].long_name);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
函数初始化(){
var input=document.getElementById('searchTextField');
var autocomplete=new google.maps.places.autocomplete(输入);
google.maps.event.addListener(自动完成,'place\u changed',函数(){
var place=autocomplete.getPlace();
document.getElementById('city2')。value=place.name;
document.getElementById('cityla')。value=place.geometry.location.lat();
document.getElementById('cityLng')。value=place.geometry.location.lng();
//警报(“此功能正在工作!”);
//警报(地点、名称);
//警报(place.address\u组件[0]。long\u名称);
});
}
google.maps.event.addDomListener(窗口“加载”,初始化);
这部分在您的表单中:
<input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on" runat="server" />
<input type="hidden" id="city2" name="city2" />
<input type="hidden" id="cityLat" name="cityLat" />
<input type="hidden" id="cityLng" name="cityLng" />
我希望它能有所帮助。您无法从自动完成API获取纬度/经度,因为google从该API生成的数据不包含纬度和逻辑度字段。 例如:-
{
"predictions" : [
{
"description" : "IIT Mumbai, Mumbai, Maharashtra, India",
"id" : "ac3235cda973818a89b5fe21ad0f5261ac9b6723",
"matched_substrings" : [
{
"length" : 10,
"offset" : 0
}
],
"reference" : "CkQ0AAAAHWg-RSngiYHHdz_yqyFKmfSoBwT-_PW0k8qQDhsbiVrk7BlPHCyJb58OthledMUTGYS5Vhec1Zj2L7w9Rq0zDxIQrbn05RX1QgWHkSXsmTk1TRoU45APW2BBRIUsA3t6XBy_8s0BPPA",
"terms" : [
{
"offset" : 0,
"value" : "IIT Mumbai"
},
{
"offset" : 12,
"value" : "Mumbai"
},
{
"offset" : 20,
"value" : "Maharashtra"
},
{
"offset" : 33,
"value" : "India"
}
],
"types" : [ "establishment", "geocode" ]
}
],
"status" : "OK"
}
您可以使用GoogleAPI从您的地址获取经度和纬度。正如您已经说过的,您应该在插入结果的地方实现一个隐藏字段。然后可以将位置与坐标一起保存
e、 g
我最近在我的一个项目中实现了此功能:
function getLatLngFromAddress(city, country){
var address = city +", "+ country;
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
$('#latitude').val(results[0].geometry.location.Pa);
$('#longitude').val(results[0].geometry.location.Qa);
} else {
console.log("Geocode was not successful for the following reason: " + status);
}
});
}
您可以从同一个api获取数据,而无需任何额外的api或url调用 HTML 是的,你可以:
var place = autocomplete.getPlace();
document.getElementById('lat').value = place.geometry.location.lat();
document.getElementById('lon').value = place.geometry.location.lng();
只需:
var place = autocomplete.getPlace();
// get lat
var lat = place.geometry.location.lat();
// get lng
var lng = place.geometry.location.lng();
您可以从place对象(即
var place = autocomplete.getPlace();
var latitude = place.geometry.location.lat();
var longitude = place.geometry.location.lng();
HTML:
//自动完成输入地址
//获得自由
//获得经度
Javascript:
<script src="https://maps.googleapis.com/maps/api/js?key=API_KEY&libraries=places&callback=initMap"
async defer></script>
<script>
var input = document.getElementById('address');
var originLatitude = document.getElementById('s_latitude');
var originLongitude = document.getElementById('s_longitude');
var originAutocomplete = new google.maps.places.Autocomplete(input);
originAutocomplete.addListener('place_changed', function(event) {
var place = originAutocomplete.getPlace();
if (place.hasOwnProperty('place_id')) {
if (!place.geometry) {
// window.alert("Autocomplete's returned place contains no geometry");
return;
}
originLatitude.value = place.geometry.location.lat();
originLongitude.value = place.geometry.location.lng();
} else {
service.textSearch({
query: place.name
}, function(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
originLatitude.value = results[0].geometry.location.lat();
originLongitude.value = results[0].geometry.location.lng();
}
});
}
});
</script>
var input=document.getElementById('address');
var originLatitude=document.getElementById('s_latitude');
var originLongitude=document.getElementById('s_-longitude');
var originAutocomplete=新的google.maps.places.Autocomplete(输入);
originAutocomplete.addListener('place\u changed',函数(事件){
var place=originAutocomplete.getPlace();
if(place.hasOwnProperty('place\u id')){
如果(!place.geometry){
//警告(“自动完成的返回位置不包含几何体”);
返回;
}
originLatitude.value=place.geometry.location.lat();
originLongitude.value=place.geometry.location.lng();
}否则{
service.textSearch({
查询:place.name
},功能(结果、状态){
if(status==google.maps.places.PlacesServiceStatus.OK){
originLatitude.value=results[0]。geometry.location.lat();
originLongitude.value=结果[0]。geometry.location.lng();
}
});
}
});
根据2020年末的情况,这很简单,如下所示
对于要在从“位置”下拉列表中选择的位置上显示的geometry
键,应使用setFields()
方法在Autocomplete
对象实例上设置字段geometry
代码应该是这样的
加载API库:
函数初始化(){
var input=document.getElementById('searchTextField');
var autocomplete=new google.maps.places.autocomplete(输入);
google.maps.event.addListener(自动完成,'place\u changed',函数(){
var place=autocomplete.getPlace();
document.getElementById('Lat')。value=place.geometry.location.Lat();
document.getElementById('Lng')。value=place.geometry.location.Lng();
});
}
google.maps.event.addDomListener(窗口“加载”,初始化);

这将有助于在不显示gmap的情况下获得lat/lon
