Question

我有以下JSON，我想提取唯一的位置，并将其放在另一个JSON或数组中，格式与以前相同。我是新手，因此，对我来说有点困惑。

这就是我所拥有的：

let data = {
    "Person"  : [{"name":"harman","comment_count":255},
                 {"name":"aman","comment_count":66},
                 {"name":"mukesh","comment_count":66}],
    "location": [{"name":"delhi","comment_count":255},
                 {"name":"mumbai","comment_count":66},
                 {"name":"chandigarh","comment_count":66}],
    "org     ": [{"name":"dell","comment_count":255},
                 {"name":"apple","comment_count":66},
                 {"name":"hp","comment_count":66}],
    "teams"  :  [{"name":"Real","comment_count":255},
                 {"name":"Juve","comment_count":66},
                 {"name":"Liverpool","comment_count":66}]        
};

这就是我想要的：

data2 = {
   "location": [
        {"name":"delhi","comment_count":255},
        {"name":"mumbai","comment_count":66},
        {"name":"chandigarh","comment_count":66}]       
};

包含下面的代码段。只需使用var data2 = data.location;祝你好运

  
  window.onload = function(){
  
      let data = {
                        "Person"  : [{"name":"harman","comment_count":255},
                                    {"name":"aman","comment_count":66},
                                    {"name":"mukesh","comment_count":66}],
                        "location": [{"name":"delhi","comment_count":255},
                                    {"name":"mumbai","comment_count":66},
                                    {"name":"chandigarh","comment_count":66}],
                        "org     ": [{"name":"dell","comment_count":255},
                                     {"name":"apple","comment_count":66},
                                     {"name":"hp","comment_count":66}],
                        "teams"  : [{"name":"Real","comment_count":255},
                                    {"name":"Juve","comment_count":66},
                                    {"name":"Liverpool","comment_count":66}]        
        };
        
       var data2 = data.location;
       console.log("data2:");
       console.log(data2);
  
  };

这样做。

data2 = data.location

如何从Angular中的JSON数据中提取特定键？
