誰知道這種json格式數(shù)據(jù)怎么來的

就是這種格式，一個(gè)數(shù)組下標(biāo)不是對應(yīng)一個(gè)值嗎，怎么可以對應(yīng)三個(gè)值出來我這邊數(shù)據(jù)就拼接成這樣，下面就沒思路了

下面是我拼接代碼
const Str = []

  for (let j = 0; j < this.role_obj.length; j++) {
    for (let i = 0; i < this.postForm.permissionList.length; i++) {
      if (this.postForm.permissionList[i].match(this.role_obj[j])) {
        Str.push(this.postForm.permissionList[i].replace(this.role_obj[j], this.role_obj[j] + ':'))
      }
    }
  }
  console.info(Str)
  this.postForm.permissionList = []
  for (let i = 0; i < Str.length; i++) {
    this.postForm.permissionList[i] = Str[i]
    console.info(this.postForm.permissionList[i])
  }
