form表单多维数组传值

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: { name: 'ceso' } }

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
