我正在使用以下内容从地理编码中获取纬度.
$latitude = $output->results[0]->geometry->location->lat; $longitude = $output->results[0]->geometry->location->lng;
如何从…中提取邮政编码
{
"status": "OK","results": [ {
"types": [ "street_address" ],"formatted_address": "1600 Amphitheatre Pkwy,Mountain View,CA 94043,USA","address_components": [ {
"long_name": "1600","short_name": "1600","types": [ "street_number" ]
},{
"long_name": "Amphitheatre Pkwy","short_name": "Amphitheatre Pkwy","types": [ "route" ]
},{
"long_name": "Mountain View","short_name": "Mountain View","types": [ "locality","political" ]
},{
"long_name": "California","short_name": "CA","types": [ "administrative_area_level_1",{
"long_name": "United States","short_name": "US","types": [ "country",{
"long_name": "94043","short_name": "94043","types": [ "postal_code" ]
} ],"geometry": {
"location": {
"lat": 37.4219720,"lng": -122.0841430
},"location_type": "ROOFTOP","viewport": {
"southwest": {
"lat": 37.4188244,"lng": -122.0872906
},"northeast": {
"lat": 37.4251196,"lng": -122.0809954
}
}
}
} ]
}
解决方法
您可以使用以下函数来提取任何地址组件：
function extractFromAdress(components,type){
for (var i=0; i<components.length; i++)
for (var j=0; j<components[i].types.length; j++)
if (components[i].types[j]==type) return components[i].long_name;
return "";
}
要提取您拨打的邮政编码：
extractFromAdress(results[0].address_components,"postal_code");
但您也可以获得其他有趣的信息,如：
extractFromAdress(results[0].address_components,"route"); extractFromAdress(results[0].address_components,"locality"); extractFromAdress(results[0].address_components,"country");
等等…
