vue3 element-plus el-tree树型组件，展开收起

在js上写下一下代码

// 展开收起树
const expandTree = () => {
expandBoolean.value = !expandBoolean.value
expandText.value = expandBoolean.value ? ‘全部收起’ : ‘全部展开’
let nodes = tree.value.store.nodesMap
console.log(‘nodes’, tree.value.store)
for (let i in nodes) {
nodes[i].expanded = expandBoolean.value
}
}
