如何设置键值

Question

consttarget=[{"title":"人物数据","value":"","children":[{"title":"本市常驻人员","value":"361,123","children":null},{"title":"本市暂住人员","value":"361,123","children":null},{"title":"本市流动人员","value":"361,123","children":null},{"title":"往来过省人员","value":"361,123","children":[{"title":"出境申请人员","value":"361,123","children":null},{"title":"火车过省人员","value":"361,123","children":null}]}]},{"title":"车辆数据","value":"","children":null}]有如下数据结构，如何将里面title都改为name呢，用递归的写法怎么也绕不过来，请高手指教。。

Answer 1

分两种情况递归，数组和对象
replace(target);
functionreplace(target){
if(targetinstanceofArray){
target.forEach(element=>{
replace(element);
});
}elseif(target&&typeoftarget==="object"){
Object.keys(target).forEach(key=>{
if(target[key]&&typeoftarget[key]==="object"){
replace(target[key]);
}
if(key==='title'){
target['name']=target[key];
deletetarget['title'];
}
});
}else{
return;
}
}
console.log(target);
