封装一个可以刷新多个指定id的节点数据。

<template>
  <el-tree ref="treeRef"></el-tree>
</template>

<script lang="ts" setup>
const treeRef = ref()

function refreshTreeById(nodeIds: number[]) {
  nodeIds.forEach((id: number) => {
    const node = treeRef.value?.getNode(id)
    if (node) {
      node.loaded = false;
      node.expand();
    }
  })
}

</script>
