1、添加虚线代码 为el-tree添加这两个属性 class="tree-line":indent="0" 完整代码 <el-treeclass="tree-line":indent="0":data="treeOption":props="defaultProps"@node-click="getCurrentNode"> style // 记得去掉scoped.tree-line{.el-tree-node{position:relative;padding-left:16px;// 缩进量}.el-...

先添加一个树 <template> <el-tree <!-- 绑定数据 --> :data="tree" highlight-current node-key="id" :props="{ children: 'children', label: 'name' }" ref="tree" > </el-tree> </template> 添加数据 export default { data() { return { tree: [ { id: 1, name: '北京', chil...

1.在label前添加指定图标： {{ node.label }} 2.在选择当前节点展开或是收起时，显⽰的图标不同：同上1，根据node.expanded判断，看是true还是false，确定当前节点是展开还是收起，以此显⽰不同图标。node中包含当前选择节点的所有信息；3.控制tree的展开或是收起：el-tree ref="treeThis"</tree>...

1.找到某个节点并进行收缩操作 <template><el-container><el-header>Header</el-header><el-containerclass="container1"><el-asideclass="aside"><el-inputplaceholder="输入关键字进行过滤"v-model="filterText"></el-input><el-treeclass="interfacetree":data="data2"node-key="id":default-expanded-key...
