问题描述
我正在尝试从自动完成Google Maps API获取纬度和经度,而不显示地图.在我的脚本中,自动补全效果很好,但是我无法获得纬度和经度.
I'm trying to get latitude and longitude from Autocomplete Google Maps API without showing the map. In my script autocompletion works well, but I can't get the latitude and longitude.
<script type="text/javascript">
function initialize() {
var options = {
types: ['(cities)']
};
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input, options);
}
google.maps.event.addDomListener(window, 'load', initialize);
var geocoder = new google.maps.Geocoder();
var address = autocomplete;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
alert(latitude);
}
});
</script>
推荐答案
您可以使用下面的代码.
You can use the code below.
<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>
这部分在您的表单内:
<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" />
希望对您有帮助.
