Uncaught TypeError：無法讀取未定義的屬性'webkit'

我正在通過Ruby on Rails教程的第8章中的示例工作，並且在我的頁面上出現上述錯誤，並且我的下拉菜單不起作用。關於如何解決這個問題的任何想法？Uncaught TypeError：無法讀取未定義的屬性'webkit'

通過與線更新您的Gemfile升級引導，青菜寶石最新版本：

gem 'bootstrap-sass', '~> 2.3.0.1'

我有問題，那是因爲我正在運行的是版本2.0.0寶石。不知道他們推薦在教程中運行哪個版本，但升級到最新版本不應該傷害您。

也適用於我（重新啓動服務器後） – nicolaspanel 2013-07-28 14:03:41

我覺得這個問題在這裏：$.browser.webkit - 顯然$ .browser已被刪除在jQuery 1.9 +。

根據this thread沒有直接替換，但是通過使用this plugin，您應該能夠恢復該標籤的功能。
