常见数据类型循环赋值：（数字判断类型）

  balMsg:[
      {
        balType:0,
        date:"2020-02-11",
        money:205
      },
      {
        balType:0,
        date:"2020-06-29",
        money:19.5
      },
      {
        balType:1,
        date:"2020-01-22",
        money:50.26
      },
      {
        balType:1,
        date:"2019-04-02",
        money:100
      },
    ]
  },
  myFn:function(){
    console.log("执行");
    for (let i = 0; i < this.data.balMsg.length; i++) {
        if(  this.data.balMsg[i].balType == 0){
          var a1="balMsg["+i+"].balType"
          this.setData({
            [a1]:"返利"
          })
        }else if(this.data.balMsg[i].balType == 1){
          var a2="balMsg["+i+"].balType"
          this.setData({
            [a2]:"提现"
          })
        }
    }
  },

　

常见for循环写法：

  wx:for-item="i"
  wx:key="k"
