优化一下这段代码：let a = thiskpiDatasthisactiveKpiTabkeycollectionAmountFinish; let b = thiskpiDatasthisactiveKpiTabkeycollectionAmountNotFinish; if b === 0 thiscollectionAmountProgress = 100

const { collectionAmountFinish, collectionAmountNotFinish } = this.kpiDatas[this.activeKpiTab.key]; if (collectionAmountNotFinish === 0 || (collectionAmountFinish === 0 && collectionAmountNotFinish === 0)) { this.collectionAmountProgress = 100; } else { this.collectionAmountProgress = Math.floor((collectionAmountFinish / (collectionAmountFinish + collectionAmountNotFinish)) * 100); } this.option1.series[0].data[0].value = 100 - this.collectionAmountProgress; this.option1.series[0].data[1].value = this.collectionAmountProgress;
