如何为数组中的值添加key

Question

arr1:[{"id":"1","keyname":"颜色"},{"id":"2","keyname":"型号"}]arr2:[["白色","测试一"],["白色","测试二"],["红色","测试一"],["红色","测试二"]]我想为arr2中的值添加key，key用的是arr1中的，得到以下结果该怎么处理：arr3:[{"颜色":"白色","型号":"测试一"},{"颜色":"白色","型号":"测试二"},{"颜色":"红色","型号":"测试一"},{"颜色":"红色","型号":"测试二"}]再给arr3添加新的属性和值得到最终：arr4:[{"颜色":"白色","型号":"测试一","测试key":"测试值"},{"颜色":"白色","型号":"测试二","测试key":"测试值"},{"颜色":"红色","型号":"测试一","测试key":"测试值"},{"颜色":"红色","型号":"测试二","测试key":"测试值"}]

Answer 1

functionmap(array,keys){
varret=[];
for(vari=0;ivarobj={};
obj[keys[0].keyname]=array[i][0];
obj[keys[1].keyname]=array[i][1];
obj["测试key"]="测试值";
ret.push(obj);
}
returnret;
}
console.log(map(arr2,arr1));
