我正在處理簡單的事件日曆。當我第一次加載日曆加載頁面。然後，當我點擊下一個或上一個時，它會將我帶到下一個月，但事件不會加載，並且月份標題不會更改，但會繪製正確的日曆。我嘗試從代碼中取出我的事件腳本，並將其放入控制ajax的函數中，但它不起作用。事件僅在第一次加載時顯示，而不是在點擊下一頁或上一頁後顯示
這是一個鏈接到頁面。 http://hartslogmuseum.com/bookhjr10/cal/final/ajcal3.php （是的，它現在是醜陋的）
有人可以指出我在正確的方向。謝謝。 這是代碼。

嗨，您發佈的代碼不會包含'$ month_name'定義的部分。這個問題與最近可能出現的$ month_name沒有正確設置有關。看起來像做一些事情:(見答案） –
