【方法】处理树结构 变换key值

function handleTree(list) {
    if (!list) {
        return []
    }
    return list.map(i => {
        const obj = {
            value: i.orgId,
            label: i.orgName,
            userId: i.userId,
            userName: i.userName,
            id: i.id
        }
        if (i.zchildren && i.zchildren.length > 0) {
            obj.children = handleTree(i.zchildren)
        }
        return obj
    })
}
