数据间字段，值的转换

Question

vararr=[{name:'color',value:'red',position:1},{name:'size',value:'s',position:2},{name:'price',value:20,position:3}]varlist=[{id:11,color:'red'},{id:12,size:'s'},{id:13,price:200},{id:14,size:'m'},{id:15,color:'pink'},{id:16,price:10},]position:1,代表字段option1，position:2,代表字段option2，position:3,代表字段option3，如何把list转成list=[{id:11,option1:'red'},{id:12,option2:'s'},{id:13,option3:200},{id:14,option2:'m'},{id:15,option1:'pink'},{id:16,option3:10},]虽然小问题，但是想不到好方法去转换.这是一时乱写的，知道是错的，但没有其他思路。请大家帮忙看看list.forEach((item,index)=>{if(item.option1==undefined||item.option2==undefined||item.option3==undefined){list.forEach((sub,subindex)=>{if(sub.name=="color"&&item.color!==undefined){item["option"+(subindex+1)]=item.color;}if(sub.name=="size"&&item.size!==undefined){item["option"+(subindex+1)]=item.size;}if(sub.name=="price"&&item.price!==undefined){item["option"+(subindex+1)]=item.price;}});}});

Answer 1

list.map(item=>{
const{id}=item
const[_,key]=Object.keys(item)
constvalue=item[key]
letobj={id}
const{position}=arr.find(({name})=>name===key)||{}
if(position){
obj[`option${position}`]=value
}
returnobj
})
                            

Answer 2

for(vari=0;ivarkey,value,position,a=list[i];
for(var_keyina){
if(_key!=="id"){
key=_key;
value=a[_key];
deletea[_key];
break;
}
}
for(varj=0;jvarb=arr[j];
varname=b.name;
if(name===key){
position=b.position;
break;
}
}
a["option"+position]=value;
}
console.log(list);
