    SL:SendNetMsg(MSGID.RANK_QUERY, RankUI.keyOf(RankUI.key),
        page, RankUI.perPage, "")

    local d = SL:JsonDecode(data)
    if not d then return end
    RankUI.clear()
    for i, row in ipairs(d.list) do
        local color = row.rank <= 3 and "#FFD700" or "#DDDDDD"
        local line = GUI:Text_Create(RankUI.list, "r" .. i,
            0, 0, 12, color,
