javascript：onclick=“scrollWin()”沒有按預期工作
[英]javascript: onclick=“scrollWin()” doesn't work as intended
問題描述
我有以下簡單頁面：
- 一個 header 左上角的名稱在您向下滾動時會消失（您會看到右下角的菜單）
- 固定的背景圖片（視差）
- 和右下角的菜單，向下滾動時會顯示（因為視差）
除了用鼠標滾動之外，我希望當您單擊頂部的名稱時，頁面應該自動向下滾動到頁面底部並顯示菜單。 問題是我的 onclick="scrollWin()" function 頁面向下滾動一毫秒並出現菜單，但隨后頁面自行向上滾動一點，菜單再次消失，而當頁面有被滾動到底部。 我認為問題可能出在視差效應上。 請問你能幫幫我嗎？
這是代碼：

yes, you can change it to be a div (notice i gave the div class="btn" and on the css i added cursor: pointer you can see working example here: https://codepen.io/Elnatan/pen/JjRvpaJ
