的getJSON然后不工作

Question

我试图用的getJSON函数来获取从JSON文件数据：

$.getJSON("uploads/data.json").then(function(data) { 
    allData = data.sculptures; 
    locations = {}; 
    for(var i=0; i<data.location.length; i++) { 
     locations[data.location[i].name] = data.location[i].location; 
    } 
    console.log(allData); 
    console.log(locations); 
}); 

，但我没有得到任何东西。当我运行在Chrome控制台开发工具的代码，那只能说明这一点：

Object {} 
     always:() 
     done:() 
     fail:() 
     pipe:() 
     progress:() 
     promise: (a) 
     state:() 
     then:() 
     __proto__: Object 

这是data.json：

{"sculptures":[{"title":"Bust of Caracalla","location":"Paris"}, 
       {"title":"Brutus The Younger","location":"Paris"}], 
"location":[{"name":"Beaux-Arts in Dijon, France","location":{"lat":47,"lng":5}}, 
      {"name":"Louvre, Paris","location":{"lat":48,"lng":2}}, 
      {"name":"St Pauls Cathedral, London","location":{"lat":51,"lng":-0}}, 
      {"name":"V&A, London","location":{"lat":51,"lng":-0}}]} 

Answer 1

locations = []; 
    $.ajax({ 
    type: "POST", 
    url: "uploads/data.json", 
    dataType: "json", 
    success: function(data) { 
     $(data.location).each(function(i, location){ 
      locations[data.location[i].name] = data.location[i].location; 
     }); 
    } 
});
