请各位大佬指点！如何实现用数组对数组进行筛选?十分感谢

Question

需求如下:letshowArr=[{malltype:'旗舰店',symbol:'R标',region:'华南地区',industry:'美容护理',price:'5万-10万'},{malltype:'旗舰店',symbol:'R标',region:'华南地区',industry:'服饰鞋包',price:'5万-10万'},{malltype:'旗舰店',symbol:'R标',region:'华南地区',industry:'游戏话费',price:'5万-10万'}]//筛选对象letreqArr=['旗舰店','服饰鞋包']//筛选条件value,且不确定对应的属性输出:[{malltype:'旗舰店',symbol:'R标',region:'华南地区',industry:'服饰鞋包',price:'5万-10万'}]目前已有的一个思路:lettemp=[];letcache;reqArr.forEach(function(item,index){showArr.forEach(function(sub){cache=Object.values(sub)cache.forEach(function(part,count){if(part==item){//console.log(item)temp=[];temp.push(sub)}})})})console.log(temp);

Answer 1

constpick=(source,values)=>source.filter(srcItem=>values.every(val=>Object.values(srcItem).includes(val)))
pick(showArr,reqArr)
                            

Answer 2

functionfind(source,target){
varret=[];
if(Array.isArray(source)&&Array.isArray(target)){
if(!target.length)returnsource;
for(vari=0;ivarobj=source[i];
vararr=target.slice();
for(varkeyinobj){
varval=obj[key];
varindex=arr.indexOf(val);
if(indexinarr)arr.splice(index,1);
}
if(!arr.length)ret.push(obj);
}
}
returnret;
}
console.log(find(showArr,reqArr));
