请教群里高手关于函数返回值循环的问题

lambilly

问题是这样的：我抓包APP获取到一组77个数组的数据，如何才能用一个函数的循环for把这77个数组的数据输送到77个sensor节点。我现在的方法如下：
我设置了一个数组分配这77个数据中的不同项目（有需要的，由于77个太多了，我暂只取12组）用了函数的12个输出各自返回一组数据。同时设置一下is_LastMonth参数来通过下面的switch节点取出上个月的数据组，把通过“获取上月”节点的数据通过第二个switch节点（费用分类）把数据组分类到不同的Sensor;


1、这是函数节点即图中的“数据分配”，这部分如何用for优化，不然我得写77个msg

var billDate = new Array();
var chargeItemName = new Array();
var billYear = new Array();
var billMonth = new Array();
var is_LastMonth = new Array();
var billAmount = new Array();
var shouldChargeDate = new Array();

var now = new Date();
var year = now.getFullYear();
var month1 = now.getMonth()+1;
var month = 0;
  if (month1 >= 1 && month1 <= 9) {
    month ="0" + month1;
  };
year= year.toString();
month = month.toString();

for (var i=0;i<=11;i++){
  billDate[i] = msg.payload.data[i].billDate;
  chargeItemName[i] = msg.payload.data[i].chargeItemName;
  if (chargeItemName[i] === "自用水费") {
    billYear[i] = billDate[i].substring(0,4);
    billMonth[i] = billDate[i].substring(13,15);
  }
  else {
    billYear[i] = billDate[i].substring(0,4);
    billMonth[i] = billDate[i].substring(4,6);
  };
  is_LastMonth[i] = month - billMonth[i];
  billAmount[i] = msg.payload.data[i].billAmount;
  shouldChargeDate[i] = msg.payload.data[i].shouldChargeDate;
}

var msg1 = {
  cost: {
    billYear: billYear[0],
    billMonth: billMonth[0],

2、以下是“获取上月”switch节点


3、以下是“费用分类”switch节点

4、其中一个Sensor的内容

上边都会用for循环了，下边为啥不继续用呢

var msgs = [];
for (var j = 0; j <= 11; j++) {
  msgs.push({
    cost: {
      billYear: billYear[j],
      billMonth: billMonth[j],
      chargeItemName: chargeItemName[j],
      billDate: billDate[j],
      billAmount: billAmount[j],
      shouldChargeDate: shouldChargeDate[j],
      isLastMonth: isLastMonth[j]
    }
  });
}

谢谢！搞定了

举例:   

$arr = ["a":"a1","b":"b1","c":"c77"];  //还有无数个.
foreach($arr as $key=>$val){
     echo $key.'====='.$val;   这里就会得到相应的键和值
     //当然你也是可以写其他的逻辑
}
