通用方法

数组合并并去重

uniqueArr(arr1, arr2,compareKey)

树数据拉平

flattenTree(tree, Key, childKey = 'children')

ReactChildren 处理方法集

浅遍历子组件并返回一个数组

ChildrenUtil.map(children, (child, index)=>{})

浅遍历子组件

ChildrenUtil.forEach(children, (child, index)=>{})

统计子组件个数

ChildrenUtil.count(children)

验证 ​children​ 是否只有一个子节点（一个 React 元素），如果有则返回它，否则此方法会抛出错误

ChildrenUtil.only(children)

把子组件转化成数组

ChildrenUtil.toArray(children)

浅过滤子组件

ChildrenUtil.filter(children, filterFn)

深层过滤子组件

ChildrenUtil.deepFilter(children, deepFilterFn)

通过 type 对子组件进行分组

ChildrenUtil.groupByType(children, types, rest)

深层遍历子组件并返回一个数组

ChildrenUtil.deepMap(children, deepMapFn)

深层遍历子组件

ChildrenUtil.deepForEach(children, deepForEachFn)

深层查找子组件

ChildrenUtil.deepFind(children, deepFindFn)

仅获取子组件及其子组件中的文本

ChildrenUtil.onlyText(children)

Local 存储

const store = LocalStore.getInstance();
store.get(A);
store.set(A,B);

权限判断

PermissionHelp(permissions,wanted)

权限组件过滤

PermissionUtil(Array, permissions)

Session 存储

保存

sessionStorage.save('SAVE_KEY',{title:'test'});

或

sessionStorage.set('SAVE_KEY',{title:'test'});

读取

sessionStorage.read('SAVE_KEY',{title:'test'});

或

sessionStorage.get('SAVE_KEY',{title:'test'});

删除

sessionStorage.remove('SAVE_KEY',{title:'test'});

数组移动
