javascript - 如何通过检查键来过滤对象

Question

我有数组对象，如果键不匹配，我想删除一些内部对象。

输入:

"configuration" : {
    "11111-2222-3333-444--5555" : {
        "home1" : 
             {
               "tel" : "125", 
               "address" : true, 
             }
    }, 
    "2222-3333-44444-5555--66666" : {
        "home2" : 
             {
               "tel" : "125", 
               "address" : true, 
             }
    }
}

我有一个匹配字符串11111-2222-3333-444--5555

预期结果:

"configuration" : {
    "11111-2222-3333-444--5555" : {
        "home1" : 
             {
               "tel" : "125", 
               "address" : true
             }
         }

   }

使用_.pick()获取你想要的 key :

var data = {"configuration":{"11111-2222-3333-444--5555":{"home1":{"tel":"125","address":true}},"2222-3333-44444-5555--66666":{"home2":{"tel":"125","address":true}}}};

var searchKey = '11111-2222-3333-444--5555';

var result = {
  configuration: _.pick(data.configuration, searchKey)
};

console.log(result);
