I want to write a public function that gets the location of the user. I currently write that the data of return is not assigned a value because of asynchronous requests, so printing locationData should be undefined. Would like to ask the gods how to write to return the data returned in the success?
< hr >public.js:
var QQMapWX = require("qqmap-wx-jssdk.js"); //
var qqmapsdk = new QQMapWX({ key: "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" });
function getLocation() {
var data;
wx.getLocation({
type: "wgs84",
success: function (res) {
let latitude = res.latitude;
let longitude = res.longitude;
qqmapsdk.reverseGeocoder({
location: {
latitude: latitude,
longitude: longitude
},
success: function (res) {
data = res.result;
}
});
},
});
return data;
}index.js:
var publicJS = require("../utils/public.js");
locationSelect: function() {
var locationData = publicJS.getLocation();
console.log(locationData);
}
