form表单多维对象赋值

原数据

let obj = {
          
   
    a.b.c:111,
    // c:2,
    a.b.d:3,
    date.name:ceso
}

目标数据

{
          
    a: {
          
    b: {
          
    c: 111, d: 3 } },
  date: {

案例

let obj = {
          
   
    a.b.c:111,
    // c:2,
    a.b.d:3,
    date.name:ceso
}
var deepExtend = require(deep-extend);//这个是写好的插件
deepExtend1//是本人简化版本的 不是特别严谨但是能用
