前言
项目需求，Web 端获取服务器文件夹目录结构。目录数据是调接口获取，本篇略过，直接展现数据！
效果
实现
html
- 代码
8 - 15行，自定义节点信息； - 代码
9 - 14行，判断icon显示；
html
<el-tree
ref="tree"
:data="treeData"
accordion
node-key="level"
:props="defaultTreeProps"
@node-click="handleNodeClick">
<span slot-scope="{ node, data }" style="display: flex;">
<!-- 父节点-未展开 -->
<i v-if="node.childNodes.length > 0 && !node.expanded" class="my-icon folder-icon"/>
<!-- 父节点-已展开 -->
<i v-else-if="node.childNodes.length > 0 && node.expanded" class="my-icon folder-open-icon"/>
<!-- 子节点 -->
<i v-else class="my-icon file-icon"/>
{{ node.label}}
</span>
