Question

我的阵列中有3个区域我为每个区域显示5个JSON。如何为5个JSON声明变量？我为区域添加数组

var arr = [
  { "region": "eu-west", "value": "http://****" },
  { "region": "eu-west", "value": "http://****" },
  { "region": "eu-west", "value": "http://****" },
] 

for (const key in arr) {
  var region= arr[key].region
  var Value = arr[key].value 

    cw.getMetricStatistics(params, function(err, data) {
    if (err){
        console.log(err, err.stack); // an error occurred
    } else {    
    var status;

    for(var i=0;i<5;i++){
    console.log(data.Datapoints[i]);
    // OUTPUT     
    /* (1) {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:32:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:29:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:35:00.000Z", Average: 200}

    (2) {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:32:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:29:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:35:00.000Z", Average: 200}

     (3) {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:32:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:26:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:29:00.000Z", Average: 200},
            {Timestamp: "2019-01-15T08:35:00.000Z", Average: 200}
     */
    }


    //******* NEED *********
    tabRg = [region1, region2, region3];
}

我的需求：

var region1 =（1）
var region2 =（2）
var region3 =（3）
