Question

我有一个巨大的JSON文件。它没有正确的结构，我无法控制结构。它是来自一组基于时间戳的路由器的数据。我正在尝试创建一个对象结构，它将给定路由器的所有信息组合成一个带时间戳等的路由器对象作为数组。 @quodlibetor是一个很大的帮助让我接近这一点。我还想从json中的名称val对的名称自动命名对象的属性。

我的目标是从json文件中的名称自动命名属性，并将其重组为一个看起来像这样的对象（我对结构的建议是开放的，这似乎是最有组织的方式）。

这是我想要的结构：

    {
        "Router": [
            {
                "routerName": "RouterID1",
                "TimeStamp": [
                    "2012/01/01 06:00:00",
                    "2013/01/01 06:00:00",
                    "2014/01/01 06:00:00"
                ],
                "OutputBITS": [
                    "23235",
                    "29903",
                    "22103"
                ],
                "InputBITS": [
                    "23235",
                    "29903",
                    "22103"
                ]
            }
        ]
    }

虽然尝试创建该结构但我已经接近但没有交易：

{
    "RouterID1": {
        "timeStamp": [
            {
                "timeStamp": "2012/01/01 06:00:00"
            },
            {
                "timeStamp": "2013/01/01 06:00:00"
            },
            {
                "timeStamp": "2014/01/01 06:00:00"
            }
        ],
        "OutputBITS": [
            {
                "OutputBITS": "23235"
            },
            {
                "OutputBITS": "23235"
            },
            {
                "OutputBITS": "23235"
            }
        ],
        "InputBITS": [
            {
                "InputBITS": "29903"
            },
            {
                "InputBITS": "29903"
            },
            {
                "InputBITS": "29903"
            }
        ]
    }
}

ORIGINAL JSON：

json = [
         {
              "Router": "RouterID1",

      }
      ];

CODE：

    //  Create routers object    
    var routers = {};


       for (var i=0;i<json.length;i++){
        var router_name = json[i].Router;
        router_name = (router_name.replace(/-/g, ""));  //take hyphen out or router name

        if (!routers[router_name]){
            // add properties to the router object thanks to @@quodlibetor

            // instead of using timeStamp is something like json[i] or json.[name] or some
            // way to reference each json property and not have to type it in?

            routers[router_name] = { timeStamp : [], OutputBITS : [], InputBITS : [] };
        }

                routers[router_name].timeStamp.push({
                    timeStamp : json[i].TimeStamp
                }); 
                 routers[router_name].OutputBITS.push({
                     OutputBITS : json[i].OutputBITS
                }); 
                routers[router_name].InputBITS.push({
                    InputBITS : json[i].InputBITS
                });  
    }; 

    console.log(routers);
    });
     </script>

以下是您需要的代码：

var router = {router: []}, i, j, k, l, inArray, routerName, thisRouter;

for(i=0,j=json.length;i<j;++i) {
    inArray = false;

    routerName = json[i].Router;

    for(k=0,l=router.router.length;k<l;++k) {
        if(router.router[k].name === routerName) {
            inArray = true; --k; l = k;
        }
    }

    if(inArray === true) {
        router.router[k].TimeStamp.push(json[i].TimeStamp);
        router.router[k].OutputBITS.push(json[i].OutputBITS);
        router.router[k].InputBITS.push(json[i].InputBITS);
    } else {
        thisRouter = {name: routerName, TimeStamp: [json[i].TimeStamp], OutputBITS: [json[i].OutputBITS], InputBITS: [json[i].InputBITS]};

        router.router.push(thisRouter);
    }
}

console.log(router);

将json自动操作到具有不同结构的对象中
