有大佬遇到过这个问题吗：json递归修改里面层级结构（已有人解答，谢谢了）大佬们有什么好的建议？

Question

这样一个需求，这样的JSON，如果当前的对象下面的type为object，则需要用一个新的对象items包裹里面的层级。例如vardataPre={"name":{"type":"string","desc":"病人姓名","testData":"张三李四","sex":{"type":"object",//这里的type为object"desc":"性别",//如果同级的type为object,需要删除这个字段"testData":"男",//如果同级的type为object,需要删除这个字段"city":{"type":"string","desc":"城市","testData":"杭州"},"street":{"type":"string","desc":"街道","testData":"浦口街道"}}},"order":{"type":"string","desc":"订单","testData":"名称"}}修改成这样的，这个JSON对象总共有三级，可能会有很对数据，大概数据结构就是这样vardataHandle={"name":{"type":"string","desc":"病人姓名","testData":"张三李四","sex":{"type":"object","items"{//这里的为新添加的对象"city":{"type":"string","desc":"城市","testData":"杭州"},"street":{"type":"string","desc":"街道","testData":"浦口街道"}}}},"order":{"type":"string","desc":"订单","testData":"名称"}}谢谢！

Answer 1

functiongenerate(obj){
let_obj={};
if(obj['type']&&obj['type']==='object'){
letitems={},flag=false;
Object.entries(obj).forEach(([key,value])=>{
if(key==='type'){
_obj[key]=value
}elseif(typeof(value)==='object'){
flag=true;
items[key]=generate(value);
}
})
if(flag){
_obj['items']=items;
}
}
else{
Object.entries(obj).forEach(([key,value])=>{
if(typeof(value)!=='object'){
_obj[key]=value
}else{
_obj[key]=generate(value);
}
})
}
return_obj
}
                            

Answer 2

functiontransform(source){
varfilterKeys=["desc","testData"];
if(source===null||typeofsource!=="object"){
returnsource;
}
Object.keys(source).forEach(key=>{
letitem=source[key];
if(item&&typeofitem==="object"&&item.type==="object"){
filterKeys.forEach(filter=>{
deleteitem[filter];
});
letkeys=Object.keys(item),
grouped={};
keys.forEach(subKey=>{
if(subKey!=="type"){
grouped[subKey]=item[subKey];
deleteitem[subKey];
}
});
item.items=transform(grouped);
}else{
source[key]=transform(item);
}
});
returnsource;
}
