七、总结
最近一周都在忙关于文件管理的东西,从提出这个需求到目前实现为止已经快一周的时间了。从最开始的找插件,然后发现没有插件可以用,再到打算自己手撸一个发现手写树状图过于困难,且因为技术力的原因估计会留下很多坑。所以在经过多方考虑以后觉得还是通过 antd-tree+手动控制的方式去实现一个文件管理页面。
下面我将着重讲解我在使用antd-tree组件时遇到的各种苦难已经官方文档中方法属性的应用。
一、selectedKeys与onSelect
官方文档
参数 | 说明 | 类型 | 版本 |
---|---|---|---|
selectedKeys | (受控)设置选中的树节点 | string[] | |
onSelect | 点击树节点触发 | function(selectedKeys, e:{selected: bool, selectedNodes, node, event}) |
代码演示
onSelect
形参:
selectedKeys: 代表当前选中的树节点的key值。获取的值的格式为:[ 'key' ]。可以通过selectedKeys[0]取值。
info: 当前选择的树节点的信息。可以通过info.selectedNodes.props.dataRef.children来获取当前节点的子节点。
注意事项
这里需要注意的是selectedKeys是一个数组类型。有且只有一个当前选中的节点key。一旦点击其他节点,数组内的值就会被替换。
如果树组件设置了selectedKeys这个属性,那么需要在onSelect函数执行时将值赋给该属性。
二、expandedKeys与onExpand
官方文档
参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
expandedKeys | (受控)展开指定的树节点 | string[] | [] | |
onExpand | 展开/收起节点时触发 | function(expandedKeys, {expanded: bool, node}) | - |
代码演示
onExpand
形参:
expandedKeys: 代表当前打开的树节点的key值。
info: 当前打开的树节点的信息。
注意事项
这里需要注意的是,expandedKeys也是一个数组的格式,但它与selectedKeys的区别是selectedKeys始终是一个长度为0或1的数组,而expandedKeys则是包含所有被打开的树节点的key值。
三、loadedKeys与onLoad和onExpand
官方文档
参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
loadedKeys | (受控)已经加载的节点,需要配合 loadData 使用 | string[] | [] | 3.7.0 |
onExpand | 展开/收起节点时触发 | function(expandedKeys, {expanded: bool, node}) | - | |
onLoad | 节点加载完毕时触发 | function(loadedKeys, {event, node}) | - | 3.7.0 |
代码演示
onExpand与onLoad:
形参:
loadedKeys:已经完成加载的树节点的key,是一个数组的数据类型。
注意事项
这里需要注意的是loadedKeys是一个数组数据类型,且可以存放多个key。一旦被加载过以后,无论怎么点击都不会再触发重新刷新重新加载了。如果想让其刷新,请移步至节点刷新。
四、loadData
官方文档
参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
loadData | 异步加载数据 | function(node) | - | |
loadedKeys | (受控)已经加载的节点,需要配合 loadData 使用 | string[] | [] | 3.7.0 |
treeData | treeNodes 数据,如果设置则不需要手动构造 TreeNode 节点(key 在整个树范围内唯一) | array\<{key, title, children, [disabled, selectable]}> | - |
代码演示
loadData:
形参:
treeNode :要加载的树节点的信息。
注意事项
这里需要注意的是如果你的树节点,是通过点击以后再加载子节点,那么对于后端的数据格式返回可能就有一些要求了。比如 title 与 isLeaf 等。当然也可以在loadData中自行设置。
loadData中代码的大概流程就是先判断 treeNode 是否有 children这个属性,注意是是否有这个属性,如果有这个属性但这个属性为空数组,在执行中也会判定为true从而不会执行更新操作,而是直接return出去。
五、树节点局部节点刷新
实现思路
因为tree的机制问题,当key节点加载过以后该节点将不会再被重新加载,因此如果我上传了一个文件,实际上服务器上已经有文件了,但因为节点刷新问题,该节点没有重新刷新,我就看不到对应的节点文件。因此需要进行局部节点刷新。
满足节点刷新的条件有这几个。
- 1. loadedKeys中移除该节点的key值和其子孙节点的key值
- 2. treeData中将该节点的children属性删除
- 3. expandedKeys中移除A节点下的所有子孙节点的key值
完成这三点以后再将selectedKeys选取到该节点 ,并将以上数据重新赋值给对应的属性即可完成节点刷新操作。
代码演示
updateTree = () =>{const { selectedKeys , expandedKeys, loadedKeys, treeData } = this.state// 获取新的expandedKeys数组,不包含该节点及子节点const newExpandedKeys = expandedKeys.filter(item =>{return item.indexOf(selectedKeys[0]) == -1})// 获取新的loadedKeys数组,不包含该节点及子节点const newLoadedKeys = loadedKeys.filter(item =>{return item.indexOf(selectedKeys[0]) == -1})const newTreedata = treeDatathis.setState({expandedKeys: [...newExpandedKeys,...[`${selectedKeys[0]}`]],loadedKeys: [...newLoadedKeys],treeData: this.removeShowData(newTreedata),selectedKeys: [`${selectedKeys[0]}`],})}// 获取新的treeData数据removeShowData = (datas) => {const { selectedKeys } = this.stateconst newData = datas;function setGrayNode(data){ //遍历树 获取id数组for(var i=0;i<data.length;i++){if(data[i].key == selectedKeys[0]){// 如果某一个节点是禁用的,它的所有子节点都应该禁用delete data[i].childrencontinue;} else {if(data[i].children){// 如果当前节点有子节点,就递归调用一次setGrayNode(data[i].children);}}}}setGrayNode(newData)return newData;}
这里需要注意的是 expandedKeys 虽然删除了当前节点,但要想操作通顺需要再次手动赋值,将该节点打开,并获取新的数据。这样就省去了用户需要再次点击节点的尴尬情况。
六、递归获取与修改数据
因为这是一个树状图,数据结构也稍微复杂一些,所以获取数据时难免需要通过递归拿取数据。所以需要一个递归函数取实现数据的拿取。
获取数据
//递归获取Showdata数据 getShowData = (datas) => {const { selectedKeys } = this.statedatas.map(item => {const { key, children } = itemif (key == selectedKeys[0]) {//符合条件this.setState({showData: datas})return}//如果有孩子,再次调用自己,将孩子传进去。if (children && children.length > 0) {this.getShowData(children)}})}
修改数据
// 获取新的treeData数据removeShowData = (datas) => {const { selectedKeys } = this.stateconst newData = datas;function setGrayNode(data){ //遍历树 获取id数组for(var i=0;i<data.length;i++){if(data[i].key == selectedKeys[0]){// 如果某一个节点是禁用的,它的所有子节点都应该禁用delete data[i].childrencontinue;} else {if(data[i].children){// 如果当前节点有子节点,就递归调用一次setGrayNode(data[i].children);}}}}setGrayNode(newData)return newData;}
七、总结
一个星期下来还是比较累的,原因是因为组件使用不熟练,且自己的技术力较弱导致的,但好在也顺利完成任务,倒也没有什么大碍。记录一下这一个星期以来遇到的一些问题和实践吧。前端小白一枚,如有错误欢迎指正。
