举例子:这是一个一维数组对象

formList:[{
affiliation: 0
affiliationInfo: "签署方1"
defaultValue:xxx
},{
affiliation: 0
affiliationInfo: "签署方1"
defaultValue:xxx
},{
affiliation: 1
affiliationInfo: "签署方2"
defaultValue:xxx
fieldFormat: xxx
},{
affiliation: 1
affiliationInfo: "签署方2"
defaultValue:xxx
fieldFormat: xxx
}]

转换二维数组对象

var arrayTwo = Object.values(
      formList.reduce((res, item) => {
    //找到相同的字段 res[item.affiliation]
? res[item.affiliation].push(item) : (res[item.affiliation] = [item]); return res; }, {}) );
console.log(arrayTwo)

结果显示如下:

arrayTwo:[
 0:[
   0:{...},
   1:{...}
  ]  
1:[    0:{...},
   1:{...}
  ] ]
