各种ui框架的 form校验 validator获取不到value

// form-item 配置prop
prop="user.name"
// rules
rules: {
  'user.name': [
     message: "xxxxx",
     validator(rule, val, callback) {
       // val 就是user.name的值
     },
  ]
}

如: 对象的sysUser.userName

js对象—modelUser

  //添加对象
const modelUser = ref({
   sysUser: {
       userId: null,
       userName: "",
       nickName: "",
       email: "",
       phonenumber: "",
       sex: "",
       avatar: "",
       password: "",
       remark: ""
   },
   sysDepts: [],
   sysRoles: [],
   sysPosts: []
})
