js 处理 json

Question

[{"add":"4","shul":"2000","yanba":"20"},{"add":"5","shul":"2001","yanba":"21"},{"add":"6","shul":"2002","yanba":"22"}]如上json想要处理成这样的格式,也就是把相同的属性对应的值放到一个数组里面。这里的属性名未知。{“add”:["4","5","6"],"shul":["2000","2001","2002"],"yanba":["20","21","22"],}

Answer 1

vardata=[
{"add":"4","shul":"2000","yanba":"20"},
{"add":"5","shul":"2001","yanba":"21"},
{"add":"6","shul":"2002","yanba":"22"}
],obj={};
data.forEach(function(d){
for(varkind){
if(!obj[k])obj[k]=[];
obj[k].push(d[k]);
}
})
                            

Answer 2

javascriptfunctiontrans(arr){
varresult={};
arr.forEach(function(val){
for(variinval){
if(typeofresult[i]=="undefined")result[i]=[];
result[i].push(val[i])
}
})
returnresult;
}
简单循环处理一下就可以了。
