javascript - Return value from custom async function -

-



this question has answer here:

i need return lat-lng coordinates google geocode api, , it. so, code seems this:

async function getjson(url){       try {            const response = await fetch(url);            return await response.json();      }      catch (err) {            console.error(err.message);      } } function getlocationforname(address){        getjson(geocodeurl+address+apikey).then(function(location){              return location.results[0].geometry.location;       }); }  somefunc(){     f['location'] = getlocationforname(city+f['street']+'+'+f['house']); }

but f['location'] alwais have undefined value

you need use callback function:

function getlocationforname(address, callback){       getjson(geocodeurl+address+apikey).then(function(location){         if (callback) callback(location.results[0].geometry.location);        }); } somefunc(){     getlocationforname(city+f['street']+'+'+f['house'], function(location){        f['location'] = location;     }); }
