javascript - 根据字段分割对象

Question

嗨，我有一个像这样的对象

var x = {code0: "codefdg", mcode0: "mcodefdg", mcode1: "mcodefdg", comments1: "commentsfdg", code3: "fdg"…}

我想像这样分割这个对象

var first = {code0:"codec",mcode0:"microcode"}
var second = {mcode1: "microcode", comments1:"commencements"} 
var forth ={code3: "fag"}

有没有办法像这样分开？ 我尝试像使用 for 循环

for(object in x){ } but i don't know what will written in inside this loop .

Answer 1

是的，这是可能的，但是我会输出一个哈希表:

var input= {code0: "codefdg", mcode0: "mcodefdg", mcode1: "mcodefdg", comments1: "commentsfdg", code3: "fdg"};
var output={}
for(var key in input){
 var id=+key.substr(-1);
 output[id]=output[id]||{};
 output[id][key.substr(0,key.length-1)]=input[key];
}

所以输出看起来像这样:

{
0:{code,mcode},
1:{mcode,comments},
3:{code}
}
