优化if语句中相同的代码案例

优化前

if ([0, 1].includes(loadType)) {
  this.energyData = res.data.energyItems;
  this.energyArr = this.energyData.length > 9 ? this.energyData.slice(0, 9) : (this.energyArr = this.energyData)
  this.getEnergyRank()
}
if ([0, 2].includes(loadType)) {
  this.constData = res.data.energyItems;
  this.costArr = this.constData.length > 9 ? this.constData.slice(0, 9) : (this.costArr = this.constData)
  this.costRank()
}

优化后

function handle({thisKey,dataKey,thisArr}) {
  this[thisKey] = res.data[dataKey];
  this[thisArr] = this[thisKey].length > 9 ? this[thisKey].slice(0, 9) : (this[thisArr] = this[thisKey])
}


let key = {
  1: {
    dataKey: 'energyItems',
    thisKey: 'energyData',
    thisArr: 'energyArr'
  },
  2: {
    dataKey: 'costItems',
    thisKey: 'constData',
    thisArr: 'costArr'
  }
}

if ([0, 1].includes(loadType)) {
  this.handle(key[1])
  this.getEnergyRank()
}
if ([0, 2].includes(loadType)) {
  this.handle(key[2])
  this.costRank()
}
