[JavaScript知识库]element ui el-cascader获取下拉列表，二级三级名称不一样，使用props

分别是一二三级，二三级名称不一样，使用props需要二三级名称一样，后台修改太大，只能前端将三级名称改为二级

selecCourse(e) {
      console.log(e)
      //获取列表
      collegeTaskgetUserList({ courseId: e }).then(res => {
        this.departmentList = res.data.deptParentVOList
        console.log(this.departmentList)
        //循环数组
        this.departmentList.map(i => {
        //在父数组中找到deptVOList二级数组，在二级数组中查找userVOList三级数组名字，改为deptVOList
          JSON.parse(JSON.stringify(i.deptVOList).replace(/userVOList/g, 'deptVOList'))
          //修改值为二级数组，将二级数组更新
          i.deptVOList = JSON.parse(JSON.stringify(i.deptVOList).replace(/userVOList/g, 'deptVOList'))
        })
        console.log('dsfd ', this.departmentList)
      })
    },

//数组格式
//一级
"deptParentVOList": [
      {
        "type": 1,
        "id": 1,
