Javascript 如何在Angular中按服务器分组

代码如下：

列表.组件.ts

如何对服务器1进行分组

输出应该是

{
   server: 'Server 1',
   data: [
{
              "id": 19,
              "dl": "35.88 Mbit/s",
              "ul": "46.76 Mbit/s",
            },
            {
              "id": 30,
              "dl": "45.06 Mbit/s",
              "ul": "48.25 Mbit/s",
            },
            {
              "id": 26,
              "dl": "47.96 Mbit/s",
              "ul": "47.89 Mbit/s",
            }
]
}

您可以使用按

server

分组，并使用语法获取

其他

对象字段：

let data=[{
“id”：19，
“服务器”：“数据1”，
“dl”：“35.88 Mbit/s”，
“ul”：“46.76 Mbit/s”，
},
{
“id”：30，
“服务器”：“数据1”，
“dl”：“45.06 Mbit/s”，
“ul”：“48.25 Mbit/s”，
},
{
“id”：26，
“服务器”：“数据1”，
“dl”：“47.96 Mbit/s”，
“ul”：“47.89Mbit/s”，
} ]
让结果=数据。减少（（状态，当前）=>{
让{server，…others}=current；
如果（状态[服务器]）{
状态[服务器]。推送（其他）；
}否则{
状态[服务器]=[其他]；
}
返回状态；
}, {});
控制台日志（结果）您还可以使用forEach对数据进行分组

let data = [
  {
    "id": 19,
    "server": "Data1",
    "dl": "35.88 Mbit/s",
    "ul": "46.76 Mbit/s",
  },
  {
    "id": 30,
    "server": "Data1",
    "dl": "45.06 Mbit/s",
    "ul": "48.25 Mbit/s",
  },
  {
    "id": 26,
    "server": "Data1",
    "dl": "47.96 Mbit/s",
    "ul": "47.89 Mbit/s",
  },
  {
    "id": 36,
    "server": "Data2",
    "dl": "41.98 Mbit/s",
    "ul": "41.82 Mbit/s",
  }
];

const groupedArray = (arr) => {
  let newArray = {};
  data.forEach(obj => {
    if(newArray[obj['server']] == undefined){
      newArray[obj['server']] = [ obj ];
    } else{
      newArray[obj['server']].push(obj);
    }
  });
  return newArray;
}

let newData = groupedArray(data);
console.log(newData);

我想我不明白你的问题。你所说的组是什么意思？我不知道你为什么不使用像这样的“lodash”lib u.groupBy（数据，“服务器”）。
let data = [
  {
    "id": 19,
    "server": "Data1",
    "dl": "35.88 Mbit/s",
    "ul": "46.76 Mbit/s",
  },
  {
    "id": 30,
    "server": "Data1",
    "dl": "45.06 Mbit/s",
    "ul": "48.25 Mbit/s",
  },
  {
    "id": 26,
    "server": "Data1",
    "dl": "47.96 Mbit/s",
    "ul": "47.89 Mbit/s",
  },
  {
    "id": 36,
    "server": "Data2",
    "dl": "41.98 Mbit/s",
    "ul": "41.82 Mbit/s",
  }
];

const groupedArray = (arr) => {
  let newArray = {};
  data.forEach(obj => {
    if(newArray[obj['server']] == undefined){
      newArray[obj['server']] = [ obj ];
    } else{
      newArray[obj['server']].push(obj);
    }
  });
  return newArray;
}

let newData = groupedArray(data);
console.log(newData);
