我帮助获得了一个jquery脚本,该脚本将通过谷歌地理编码系统对键入的位置进行地理编码。
我需要将国家/地区的short_name放入国家/地区字段中。对于我的生活,我无法理解我应该如何整合,而我尝试的每件事都没有回报价值。任何人都可以请一些有关实现这一目标的正确方法的见解吗?
JSFIDDLE:http://jsfiddle.net/spadez/jCB4s/2/
$(function () {
var input = $("#loc"),
lat = $("#lat"),
lng = $("#lng"),
lastQuery = null,
lastResult = null, // new!
autocomplete;
function processLocation(callback) { // accept a callback argument
var query = $.trim(input.val()),
geocoder;
// if query is empty or the same as last time...
if( !query || query == lastQuery ) {
callback(lastResult); // send the same result as before
return; // and stop here
}
lastQuery = query; // store for next time
geocoder = new google.maps.Geocoder();
geocoder.geocode({ address: query }, function(results, status) {
if( status === google.maps.GeocoderStatus.OK ) {
lat.val(results[0].geometry.location.lat());
lng.val(results[0].geometry.location.lng());
lastResult = true; // success!
} else {
alert("Sorry - We couldn't find this location. Please try an alternative");
lastResult = false; // failure!
}
callback(lastResult); // send the result back
});
}
autocomplete = new google.maps.places.Autocomplete(input[0], {
types: ["geocode"],
componentRestrictions: {
country: "uk"
}
});
google.maps.event.addListener(autocomplete, 'place_changed', processLocation);
$('#searchform').on('submit', function (event) {
var form = this;
event.preventDefault(); // stop the submission
processLocation(function (success) {
if( success ) { // if the geocoding succeeded, submit the form
form.submit()
}
});
});
});
根据API,我需要这个:
results[]: {
types[]: string,
formatted_address: string,
address_components[]: {
short_name: string,
long_name: string,
types[]: string
},
geometry: {
location: LatLng,
location_type: GeocoderLocationType
viewport: LatLngBounds,
bounds: LatLngBounds
}
}
答案 0 :(得分:1)
通过搜索结果寻找具有“country”类型的结果
Example that does that looking for a result with a type of "postal_code"
这样的事情应该有效(未经测试):
geocoder.geocode({ address: query }, function(results, status) {
if( status === google.maps.GeocoderStatus.OK ) {
lat.val(results[0].geometry.location.lat());
lng.val(results[0].geometry.location.lng());
var address = results[0].address_components;
for (var p = address.length-1; p >= 0; p--) {
if (address[p].types.indexOf("country") != -1) {
// do something useful with the country...
// document.getElementById('postcode').innerHTML= address[p].long_name;
}
}
lastResult = true; // success!
} else {
alert("Sorry - We couldn't find this location. Please try an alternative");
lastResult = false; // failure!
}
callback(lastResult); // send the result back
});
