今天主要练习了vue中组件的使用，采用多个状态值去优化冗余代码

<script setup>
import { ref, onMounted } from 'vue'
import { findAll, addStudent, updateStudent, deleteStudent} from "@/apis/student.js";

const students = ref([])

const student = ref({
  number: '',
  name: '',
  age: '',
  sex: '',
  birthday: ''
})

const dialogFormVisible = ref(false)
const dialogFormType = ref('add')

const handleAdd = () => {
  dialogFormVisible.value = true
  dialogFormType.value = 'add'
  student.value = {
    number: '',
    name: '',
    age: '',
    sex: '',
    birthday: ''
  }
}

const handleEdit = (row) => {
  dialogFormVisible.value = true
  dialogFormType.value = 'edit'
  student.value = row
}

const handleDelete = (row) => {
  deleteStudent(row.id).then(res => {
    findAll().then(res => {
      students.value = res.data
    })
  })
}

const handleConfirm = () => {
  if (student.value.id) {
    updateStudent(student.value).then(res => {
      findAll().then(res => {
        students.value = res.data
      })
    })
  } else {
    addStudent(student.value).then(res => {
      findAll().then(res => {
        students.value = res.data
      })
    })
  }
  dialogFormVisible.value = false
}


onMounted(async () => {
  findAll().then(res => {
    students.value = res.data
  })
})
</script>
