使用该片段，并检查你的开发人员工具控制台查看错误：

var options = { 
    enableHighAccuracy: true, 
    timeout: 5000, 
    maximumAge: 0 
}; 

function success(pos) { 
    var crd = pos.coords; 

    console.log('Your current position is:'); 
    console.log('Latitude : ' + crd.latitude); 
    console.log('Longitude: ' + crd.longitude); 
    console.log('More or less ' + crd.accuracy + ' meters.'); 
}; 

function error(err) { 
    console.warn('ERROR(' + err.code + '): ' + err.message); 
}; 

navigator.geolocation.getCurrentPosition(success, error, options);
