问成功不会在getJson之后触发

EN

$.getJSON('https://nominatim.openstreetmap.org/reverse', {
    lat: lat,
    lon: lng,
    format: 'json',
}, function (result) {
   var dn = result;
   var phn = localStorage.getItem("number");
    var new_dn = JSON.stringify(dn);
    $.ajax({ 
            url: 'http://cnn.com/nj.php' ,
            type : "POST",            
            data: {phone: phn, location: new_dn },
            dataType: 'json',
            success: function()
            {
                alert('success'); 
            }            
      });
});

success: function()
                {
                    alert('success'); 
                }
