vue3使用ts开发自定义组件，对外开放方法

defineExpose({
  showCreate,
  showView,
  showEdit
})

<data-edit ref="editRef" @on-create="onSuccessCreate" @on-update="onSuccessUpdate"></data-edit>

import DataEdit from './drawer-edit.vue'
const editRef = ref<InstanceType<typeof DataEdit>>()
/**
 * 新增
 */
const onClickAdd = () => {
  editRef.value?.showCreate()
}
