Parsing Google Maps JSON data for Geocoding in JQ (Not JQuery) - json

Question

I am trying to get the Country and City names from Lat and Long values with JQ.
Here is the full example JSON
https://maps.googleapis.com/maps/api/geocode/json?latlng=55.397563,10.39870099999996&sensor=false
I pasted returned JSON in jqplay,
Tried to select Country and City names, but the closest I get is
.results[0].address_components[].short_name
How can I specify just bring the nodes where "types" : [ "country", "political" ] ?
Thanks

Answer 1

It's unclear to me what exactly you're looking for. Each result has a set of types, each address component also has a set of types. Which one did you want? We can write a filter that will match what you attempted but considering the data, it will be completely useless to you. The only item that contains the types you listed is just a country name.
Anyway, assuming you wanted to get a result object that had the types "country" and "political", use the contains() filter.
.results | map(
select(
.types | contains(["country","political"])
)
)
Otherwise you'll need to clarify what exactly you wanted from this data set. An example of the expected results...

I wrote a function to do this.
/**
* geocodeResponse is an object full of address data.
* This function will "fish" for the right value
*
* example: type = 'postal_code' =>
* geocodeResponse.address_components[5].types[1] = 'postal_code'
* geocodeResponse.address_components[5].long_name = '1000'
*
* type = 'route' =>
* geocodeResponse.address_components[1].types[1] = 'route'
* geocodeResponse.address_components[1].long_name = 'Wetstraat'
*/
function addresComponent(type, geocodeResponse, shortName) {
for(var i=0; i < geocodeResponse.address_components.length; i++) {
for (var j=0; j < geocodeResponse.address_components[i].types.length; j++) {
if (geocodeResponse.address_components[i].types[j] == type) {
if (shortName) {
return geocodeResponse.address_components[i].short_name;
}
else {
return geocodeResponse.address_components[i].long_name;
}
}
}
}
return '';
}
The way to use it; an example:
...
myGeocoder.geocode({'latLng': marker.getPosition()}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK && results[1]) {
var country = addresComponent('country', results[1], true);
var postal_code = addresComponent('postal_code', results[1], true);
...
}
});
...
I used it here: saving marker data into db

Assign the json to results variable, var results = {your json}.
Then try this :
for( var idx in results.results)
{
var address = results.results[idx].address_components;
for(var elmIdx in address)
{
if(address[elmIdx].types.indexOf("country") > -1 &&
address[elmIdx].types.indexOf("political") > -1)
{
address[elmIdx].short_name //this is the country name
address[elmIdx].long_name //this is the country name
}
}
}
