树状数据展示,可以点击item 将点击数据给父组件 ,满足自己需求。不喜勿喷,很简单可以根据自己需求改哈,不要问,点赞收藏就好。其实可以和上一篇文章uni app 自定义 带popup弹窗的input组件-CSDN博客结合使用,做成输入框带popup展示树状结构数据

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
},
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,

ishow: false,
isopen: true,
children: [{

ishow: false,
isopen: true,
children: [{

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_back=222==", 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
