Js uses Baidu map to locate and obtain longitude and latitude

The positioning function needs to be used in recent projects, and the longitude and latitude of the current position are obtained. The following code is compiled for reference:

Function locationPosition (){
Var geolocation = new BMap. Geolocation ();
Geolocation. getCurrentPosition (function (r ){
 
Var city_lat = r. latitude;
Var city_lng = r. Longpolling;
 
Cookies. set ("save_city_latitude", city_lat );
Cookies. set ("save_city_long.pdf", city_lng );
// Console. log (city_lat );
// Console. log (city_lng );
If (this. getStatus () = BMAP_STATUS_SUCCESS ){
Var geoc = new BMap. Geocoder ();
Var pt = r. point;
Geoc. getLocation (pt, function (rs ){
// Obtain the longitude and latitude
 
Var addComp = rs. addressComponents;
 
// Alert (addComp. province + "," + addComp. city + "," + addComp. district + "," + addComp. street + "," + addComp. streetNumber );
$ City = $ (". head-left> a> span ");
// Var city_name = $. fn. cookie ('location _ City ');
Var city_name = Cookies. get ('location _ City ');
// Console. log (addComp. city );
If (city_name = addComp. city ){
// If the location of the TODO city is the same as the cookie value, no operation is performed.
$ City. text (addComp. city );
$ (". City-now"). text (addComp. city );
} Else {
$ City. text (city_name );
If (confirm ('the current location is different from the location of the target city, are you sure you want to change it to the current location? ')){
$ City. text (addComp. city );
$ (". City-now"). text (addComp. city );
// $. Fn. cookie ('location _ City', addComp. city );
// Cookies. set ('location _ City', addComp. city );
// SetLocation ();
}
}
 
Var city = Cookies. set ('location _ City', addComp. city );
 
Currount_city_name = addComp. city;
 
GetData (1, city_lat, city_lng, currount_city_name );
GetArea (currount_city_name );
 
});
}
Else {
Alert ('locating failed ');
 
}
 
},{ EnableHighAccuracy: true });
 
}
 
LocationPosition ();

Where:

Var city_lat = r. latitude;
Var city_lng = r. Longpolling;
You can obtain the current longitude and latitude.
