有嗎？ （我想要這個是因為7 n.\,1如果頁面上有多個註釋並且7\,n.
附言。根據要求，更清楚地說明：可以定義一個\fnnonthispage返回目前頁面上腳註數量的巨集嗎？我不知道如何說得更清楚。
附註二。以下是該巨集的使用方法。第一頁有兩個註釋，因此條目應註明編號；但 p. 2、只有一個，所以不應該指定數量。如果頁麵包含部分腳註，也應算作一個。

這是一個解決方案。如果沒有\mtfnexiste<pagenumber>定義宏，我們檢查每個輸出頁面是否有多個腳註。
筆記John Kormylo 的上述評論很重要，但我沒有註意到這裡的要點。讓我知道。

更新長腳註的範例，它是第一頁中的第二個腳註，但索引詞在第二頁中，其中只有一個腳註，所以問題！
