嵌套数据处理

后端给的数据：

"sidebarRouters": [

{

"key": "0",

"icon": "el-icon-s-home",

"title": "首页",

"url": "/index"

},

{

"key": "1",

"icon": "el-icon-s-tools",

"title": "系统管理",

"url": "/systemManage",

"children": [

{

"key": "0",

"icon": "el-icon-menu",

"title": "菜单管理",

"url": "/menuManage"

},

{

"key": "1",

"icon": "el-icon-s-custom",

"title": "部门管理",

"url": "/partManage"

},

{

"key": "2",

"icon": "el-icon-suitcase",

"title": "岗位管理",

"url": "/jobManage"

},

{

"key": "3",

"icon": "el-icon-notebook-2",

"title": "日志管理",

"url": "/dayManage",

"children": [

{

"key": "0",

"icon": "el-icon-thumb",

"title": "操作日志",

"url": "/operationManage"

},

{

"key": "1",

"icon": "el-icon-s-custom",

"title": "登陆日志",

"url": "/loginManage"

}

]

}

]

},

{

"key": "2",

"icon": "el-icon-user",

"title": "用户管理",

"url": "/useManage"

},

{

"key": "3",

"icon": "el-icon-help",

"title": "其他",

"url": "/other",

"children": [

{

"key": "0",

"icon": "el-icon-date",

"title": "其他1",

"url": "/other1"

},

{

"key": "1",

"icon": "el-icon-paperclip",

"title": "其他2",

"url": "/other2"

}

]

}

]

 

目标：把所有的url取出作为单独数组

function filterPermissions(navMenuData) {

let children = []

navMenuData.forEach(el => {

if (el.children && el.children.length) {

return el.children.forEach(c => {

if (c.children && c.children.length) {

return (children = children.concat(filterPermissions(c.children)))

}

children.push(c.url)

})

} else {

children.push(el.url)

}

})

return children

}

const permissionList = filterPermissions(sidebarRouters)

console.log(permissionList)

结果： ['/index', '/menuManage', '/partManage', '/jobManage', '/operationManage', '/loginManage', '/useManage', '/other1', '/other2']
