一、示例代码

（1）/src/views/Example/ExpandToggle/index.vue

 
<script setup lang="ts">
import { onMounted, ref } from "vue";
import { ArrowUp, ArrowDown } from "@element-plus/icons-vue";
 
const ewRef = ref(); // 实例
const isExpand = ref(false); // 是否展开
 
onMounted(() => {
  console.log('ewRef =>', ewRef)
  if (ewRef.value) {
    if (ewRef.value.scrollHeight > ewRef.value.clientHeight) {
      // ...
    }
  }
});
