自定义校验规则( 判断列表是否含有该内容 )

// 自定义校验--部门编码是否重复,value输入的内容
const validCode = (rule: any, value: any, callback: any) => {
  const existCodeList = parseId.deptsList.map(item => (item as ItDepartmentsItem).code)
  existCodeList.includes(value) ? callback(new Error('编码' + value + '已经存在')) : callback()
  console.log(existCodeList);
}

 code: [
      { required: true, message: '部门编码不能为空', trigger: 'blur' },
      { min: 1, max: 50, message: '部门编码要求1-50个字符', trigger: 'blur' },
      { validator: validCode, trigger: 'blur' }
   ]
