如何使用HTML5地理定位或Google API获取地址的经纬度？

if (navigator.geolocation) {   /*  If current position is obtained then there is success otherwise there is failure.   On failure, separate error message is shown  */       navigator.geolocation.getCurrentPosition(successFunc, errorFunc);}  else {       alert(‘Geolocation is not enabled in your browser. Please use a latest browser to supports it.');}
