一、使用 vue 頁面實現
- 缺點一:見視頻第18秒,先將列表向上滾動一部分內容,再一口氣滑到頂部(即用力一滑,讓頁面自動滾動到頂部),會直接出發下拉刷新,一般是到頂部後就停了,再下拉纔會觸發下拉刷新,不過很多人滑到頂部本身就習慣再多下拉一下,刷新頁面,保證到了頂部以及獲取最新的數據,這有可能剛好符合某些人的需要。
- 缺點二:見視頻第20秒,下拉刷新與滑動切換可能會同時觸發,導致感覺上不完美,但是不影響功能,不會導致bug,出現這個效果是因爲列表在頂部了,此時手指斜向下拉,同時觸發了滑動和下拉刷新的事件導致,不故意這麼做的話,一般不會產生這種問題,即使故意這麼做了,也不會導致數據加載錯誤。
- 缺點一優化方案:使用一個 flag 做爲 refresher-enabled 的屬性值,判斷滾動區域內容當前是否在最頂部,如果不在頂部,該值爲 false,否則爲 true。
- 缺點二優化方案:同樣使用一個 flag 做爲 refresher-enabled 的屬性值,同時使用 @transition 和 @animationfinish 監聽 swiper 窗口是否開始滑動或滑動結束,在滑動開始時 flag = false,結束時 flag = true。
- refresher-enabled 爲 scroll-view 的屬性,作用是設置是否可下拉刷新。

二、使用 nvue 頁面實現
- 這個方式沒有以上 vue 頁面方式的2個缺點,但有其他缺點
- 缺點一:使用的是 nvue 頁面,nvue 頁面的 css 樣式不支持很多特性
- 缺點二:nvue 頁面不支持常規模式引入的 iconfont 文字圖標,必須使用其特定的方式引入,目前我試過,但還沒試成功
index.nvue 頁面代碼(其內部組件可以是 vue 頁面)
