讲一下 treeData 树状数据 uselast 只能使用末级 showkey 列表要展示的字段 zjflag 树状结构第几层默认0开始
使用 在父组件
引用组件
import TreeNode from ./TreeNode.vue;
components: { TreeNode }, tree-node :tree-datatreeData uselasttrue callBacktree_node_back/tree-node treeData: [{ id: 1, name: 节点1, ishow: false, isopen: true, children: [{ id: 2, name: 子1-节点1, ishow: false, isopen: true, children: [] }, { id: 3, name: 子2-节点1, ishow: false, isopen: true, children: [{ id: 4, name: 孙1-子2-节点1, ishow: false, isopen: true, children: [] }] }, ], }, { id: 5, name: 节点2, ishow: false, isopen: true, children: [{ id: 6, name: 子1-节点2, ishow: false, isopen: true, children: [{ id: 8, name: 孙1-子1-节点2, ishow: false, isopen: true, children: [{ id: 8, name: 重1-孙1-子1-节点2, ishow: false, isopen: true, children: [{ id: 9, name: 曾1-重1-孙1-子1-节点2, ishow: false, isopen: true, children: [{ id: 9, name: 僧1-曾1-重1-孙1-子1-节点2, ishow: false, isopen: true, children: [] }] }] }] }] }, { id: 7, name: 子2-节点2, ishow: false, isopen: true, children: [{ id: 8, name: 孙1-子2-节点2, ishow: false, isopen: true, children: [{ id: 8, name: 重1-孙1-子2-节点2, ishow: false, isopen: true, children: [{ id: 9, name: 曾1-重1-孙1-子2-节点2, ishow: false, isopen: true, children: [{ id: 9, name: 僧1-曾1-重1-孙1-子2-节点2, ishow: false, isopen: true, children: [] }] }] }] }] }, ], }, ], tree_node_back: function(e) { if (e.mydetail) { this.tree_node_back(e.mydetail) } else { console.log(tree_node_back222, JSON.stringify(e)) } }, 注意 treedata 中 isshow 是翻着的 false 展示 true 隐藏 isopen 是正常 false 关闭 true 展开
