请教各位一个问题，求解答：js怎么遍历给对象赋值求老司机指点！

Question

这看起来有点繁琐，可以简化也行，新手，谢谢大佬，感谢getChartsData(this.rule).then(res=>{letobj=res.data.data[0];this.compRegion.lineCode=obj.lineCode;this.compRegion.lineCodeName=obj.lineCodeName;this.compRegion.timeRate=obj.timeRate;this.compRegion.performanceRate=obj.performanceRate;this.compRegion.percentRate=obj.percentRate;this.compRegion.deviceRate=obj.deviceRate;this.compRegion.deviceOee=obj.deviceOee;this.compRegion.deviceTeep=obj.deviceTeep;this.compRegion.startRate=obj.startRate;this.compRegion.planRate=obj.planRate;});

Answer 1

这样？
getChartsData(this.rule).then(res=>{
letobj=res.data.data[0];
letneedKey=['lineCode','lineCodeName','timeRate','performanceRate','percentRate','deviceRate','deviceOee','deviceTeep','startRate','planRate']
needKey.forEach(item=>{
this.compRegion[item]=obj[item]
})
});
                            

Answer 2

//解构
this.compRegion={...res.data.data[0]}
//如果还有一些多余的字段不想带进去可以使用only这库
importonlyform'only'
//前提this.compRegion有初始属性
this.compRegion=only(res.data.data[0],Object.keys(this.compRegion))
