我目前正在建立一個輪盤系統程式(這更多的是為了阻止我下注而不是下注!)並且我只是在做基本框架,但已經遇到了主視窗「#results」不滾動的問題充滿了結果。捲動需要跟隨最新的內容行,因此從模式框中輸入返回的最新內容始終顯示在底部。我花了幾個小時研究許多可能的解決方案,但都無濟於事。
這是程式碼:(對於完整腳本的長度,我深表歉意)

我在 Stack Overflow 和互聯網上的其他領域嘗試了很多解決方案,我認為這些解決方案可能有效,但它似乎不想這樣做。

在 Results div 中新增元素後,您必須呼叫此函數。
新增此功能 window.scrollTo(0, document.body.scrollHeight) 在此行之後 resultsDiv.innerHTML = resultHTML;
