【需求】：如下图所示，当点击左侧仓库时，显示对应的页面权限以及按钮权限。
【技术点】：处理树状结构
需求图
【页面代码】
let targetArr = [],
expandArr = []
let authorityArr = []
if (res.datas && res.datas.length) {
getAllKeysValues(res.datas, targetArr, expandArr, authorityArr, 'id', 'subs')
}
addCheckedFlag(this.rigthTreeData, targetArr, expandArr, authorityArr, 'id', 'subs')
【工具类函数代码】
// 获取数组（包括子节点）的全部子节点id
export function getAllKeysValues(treeArr, targetArr, expandArr, authorityArr, key = 'id', children = 'subs') {
treeArr.map(item => {
expandArr.push(item[key])
if (item.hasOwnProperty('authorityDtos') && item['authorityDtos'] && item['authorityDtos'].length) {
item['authorityDtos'].map(it => {
authorityArr.push(it['value'])
})
}
if (item.hasOwnProperty(children) && item[children].length) {
getAllKeysValues(item[children], targetArr, expandArr, authorityArr, key, children)
} else {
targetArr.push(item[key])
}
})
}
// 给过滤出的id加选中标识
export function addCheckedFlag(treeArr, idsArr, expandArr, authorityArr, key = 'id', children = 'subs') {
treeArr.map(item => {
item.checked = false
if (item.hasOwnProperty('authorityDtos') && item['authorityDtos'] && item['authorityDtos'].length) {
item['authorityDtos'].map(its => {
if (authorityArr.findIndex(it => it == its['id']) != -1) {
its.checked = true
} else {
its.checked = false
}
})
} else {
if (idsArr.findIndex(it => it == item[key]) != -1) {
item.checked = true
}
}
if (expandArr.findIndex(it => it == item[key]) != -1) {
item.expand = true
} else {
item.expand = false
}
if (item.hasOwnProperty(children) && item[children].length) {
addCheckedFlag(item[children], idsArr, expandArr, authorityArr, key, children)
}
})
}
【编程逻辑】：有按钮权限时就一定有页面权限，没有按钮权限时再去考虑有无页面权限！
