vue3+antd-vue实现增改弹窗

对于前端来说，在后台系统中最常见的需求，就是基于表单表格的正删改查。对于增和改，需要实现弹框组件。代码如下：

<template>
  <div>
    <a-modal
      :title="modalTitle"
      v-model:visible="visible"
      cancelText="取消"
      okText="提交"
    >
      <a-form
        :model="formState"
        name="classForm"
        ref="formRef"
        :label-col="{ span: 5 }"
        :wrapper-col="{ span: 16 }"
      >
        <a-form-item
          label="学校名称"
          name="schoolId"
          :rules="[{ required: true, message: '请选择学校', trigger: 'blur' }]"
        >
          <a-select
            allowClear
            :options="[
              { label: '学校1', value: 1 },
              { label: '学校2', value: 2 }
            ]"
            placeholder="选择学校"
            v-model:value="formState.schoolId"
          ></a-select>
        </a-form-item>
        <a-form-item
          label="班课名称"
          name="courseName"
          :rules="[{ required: true, message: '请输入班课名称' }]"
        >
          <a-input
            allowClear
            placeholder="输入班课名称"
            v-model:value="formState.courseName"
          ></a-input>
        </a-form-item>
      </a-form>
    </a-modal>
  </div>
</template>

<script setup>
import { reactive, ref, nextTick, computed } from 'vue'

const ModalOpenType = {
  ADD: 0,
  EDIT: 1
}
const visible = ref(false)
const formRef = ref(null)

const operationName= ref('')
const props = defineProps(['name'])
const modalTitle = computed(() => operationName.value + props.name)

const resetForm = () => {
  formRef.value.clearValidate()
  formRef.value.resetFields()
}

const open = (type, id) => {
  visible.value = true
  nextTick(async () => {
    resetForm()
    console.log(props)
    if (type === ModalOpenType.EDIT) {
      operationName.value = '编辑'
      const rowData = await getRowById(id)
      replaceFormFieldsValues(rowData)
    } else {
      operationName.value = '新增'
    }
  })
}

const getRowById = id => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve({
        schoolId: 2,
        courseName: 'qwe'
      })
    }, 300)
  })
}

const formState = reactive({
  schoolId: null,
  courseName: ''
})

const replaceFormFieldsValues = data => {
  Object.keys(data).forEach(key => {
    formState[key] = data[key]
  })
}

defineExpose({
  open
})
</script>

<style lang="" scoped></style>

使用方法：

模板使用组件

 <ClassModal ref="classModal" :name="`班课`"/>

控制打开弹窗

<a-button size="small" type="primary" style="margin-right: 10px" @click="openModal(ModalOpenType.EDIT, record.id)">编辑</a-button>

js

const classModal = ref(null)

function openModal(type) {
  classModal.value.open(type)
}
