解决el-tree中default-expand-all动态加载全部不生效问题

<el-tree
v-if=“refreshTree”
:data=“deviceList”
:props=“defaultProps”
:load=“loadNodeTree”
:filter-node-method=“filterNode”
lazy
:default-expand-all=“deviceType”
ref=“tree”
@node-click=“handleNodeClick”
/>
首先添加v-if=“refreshTree”，然后在点击事件中使用this.KaTeX parse error: Expected '}', got 'EOF' at end of input: …lse this.nextTick(()=>{
this.refreshTree = true
})
},
