我已經反應鉻擴展安裝,我知道它的工作,因爲它顯示在instagram.com上。不過,我經歷的陣營教程(http://facebook.github.io/react/docs/tutorial.html)和反應選項卡不顯示在我的控制檯窗口這裏是我的所有代碼:反應開發者控制檯不顯示

我的控制檯說以下內容:

Uncaught Error: Parse Error: Line 41: Unexpected identifier
我在那裏有一個錯誤,但我試圖讓React選項卡暫時顯示並且不太確定如何執行它。
後''在你CommentBox'忘記添加逗號 – Dhiraj 2015-03-02 21:34:11
THX,顯然是錯誤是防止裝載 – Saad 2015-03-02 21:41:16
如果你的反應擴展componentDidMount'方法有一個解決方案,你可以寫在提供的答案框中,然後接受它。 (或刪除問題)。這比編輯單詞「解決」成問題更好,這將問題留在「未答覆」隊列中,永遠是永久性的。 – 2015-04-26 15:33:10
