latitude degree. Thus, the latitude of a land is the direction and angular distance of the equator. Equator is0° latitude, the maximum value of northern latitude is 90°, that is, the North Pole, the maximum latitude is 90°, that is, the Antarctic point.Interchange by latitu

(); geocoder. getlocations ( 'Shandong Qingdao ', Function($ ){ VaRLalton = $. placemark [0]. Point. Coordinates; Alert (latlon [0] + "," + latlon [1]); }); But how should PHP obtain the longitude and latitude? Today, I saw a WP plug-in without intention. I found the method to obtain the latitude and longitude through

circle = new BMap. geolocation (); var options ={}; options. enableHighAccuracy = true; options. timeout = 10; options. maximumAge = 0; circle. getCurrentPosition (locationResult, options); // enableHighAccuracyBoolean requires the browser to obtain the best result ., TimeoutNumber timeout time ., MaximumAgeNumber allows you to return cache results within a specified period of time. If the value is 0, the browser immediately obtains the new positioning result. Map. addOverlay (circle); var temp
