   const changeType = (data: any) => {
        const { TreeDataList } = props
        let type = "2"
        TreeDataList && TreeDataList.map((item: IItem, index: number) => {
            if (item.key == data[0]) {
                type = "0"
                return type
            }
            item.children && item.children.map((item1: IItem, index: number) => {
                if (item1.key == data[0]) {
                    type = "1"
                    return type
                }
