AngularJS JavaScript解析JSON的一部分

I have the following JSON. I have a parameter to give and I need to return all the number.

我有以下JSON。我有一个参数,我需要返回所有数字。

If I give "BUS", I need to return1,38,44,58

如果我给“BUS”,我需要返回1,38,44,58

Example of JSON:

JSON示例:

{  
   _id:"23456789",
   result:[  
      [  
         "Car",
         [  
            [  
               2,
               3,
               4,
               6
            ],
            [  
               3,
               4,
               444,
               123
            ],
            [  
               43,
               34,
               91446,
               344473
            ]
         ]
      ],
      [  
         "Bus",
         [  
            [  
               1,
               38,
               4458,
               0981
            ]
         ]
      ],
      [  
         "Moto",
         [  
            [  
               5,
               43,
               41440,
               804444
            ]
         ]
      ]
   ]
}

This is my code:

这是我的代码:

    var coordinates = [];
    console.log("tag :"+tag); // tag is the parameter "Bus", "Car" or "Moto"
    $http.get('http://myserver:1234/bbox/'+id)
                    .success(function (response) {
                var point = {};
                // Don't know how to catch a specific word (i.e Car or BUS or Moto)
                for (var i in response){
                    var pointName =  response.result[i][0];
                    coordinates.push(response.result[i][1]);
                    points[pointName] = coordinates;
                }

    })
    .error(function (response) {
        console.log(response);
     });

tag is already set with only one parameter. Just need to return the coordinate for one given.

tag已经只设置了一个参数。只需要返回一个给定的坐标。

Thanks for your help!

谢谢你的帮助!

This is pretty strange structure for JSON response, but you can still extract necessary data. For example using Array.prototype.filter method:

对于JSON响应,这是非常奇怪的结构,但您仍然可以提取必要的数据。例如,使用Array.prototype.filter方法:

var coordinates = response.result.filter(function(el) {
    return el[0] === tag;
})[0][1][0];

For tag equal to "Bus" above code will give you [1, 38, 4458, 981] array.

对于等于“Bus”的代码,代码将为您提供[1,38,4458,981]数组。
