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[][]3.7.0onExpand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[][]3.7.0treeDatatreeNodes 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。
- loadedKeys中移除该节点的key值和其子孙节点的key值
- treeData中将该节点的children属性删除
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 = treeData
this.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.state
const 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].children
continue;
} 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.state
datas.map(item => {
const { key, children } = item
if (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.state
const 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].children
continue;
} 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。
