setup() defineExpose is not defined

根据您提供的信息， 'defineExpose' is not defined 错误是因为在Vue3.2版本中，使用语法糖需要在 `<script>` 标签上加上 `setup` 属性，无需使用 `defineExpose` 。 正确的代码示例如下：

<script lang="ts" setup>
  const showModal = (data: any, val: string) => {
    console.log("data=====",data);
    visible.value = true;
    if (data) {
      console.log("编辑=====")
      uuid.value = data.bizCode;
      getData()
      title.value = "编辑";
      formState.value = data;
    } else {
      console.log("新增=====",val)
      title.value = "新增";
      uuid.value = val;
      dataSource.value= []
      formState.value = { title: "", illustrate: "" };
    }
  };
</script>

请注意，'defineExpose' 在Vue3.2中已不再使用，您可以直接在 `setup` 函数内部定义组件的方法和数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
