我已經將我的導航放置在手風琴按鈕/選項卡中，因爲我希望用戶能夠點擊該選項卡，並讓他們隨時查看導航。地圖和所有使用地圖的代碼是完全有效的，因爲當我在控制檯上測試它時沒有錯誤，但由於某些原因它仍然不顯示。我也使用了API Key。它只會在我用控制檯測試它時才起作用。爲什麼我點擊標籤時不顯示地圖？爲什麼我的地圖不顯示在Accordion選項卡中？
這是代碼我有我的地圖

不顯示或顯示灰色區域？ – scaisEdge
它只是顯示一個帶有標記圖標的灰色區域，沒有離開地圖的衛星視圖 – Toby
這是因爲你在啓動時沒有visibile標籤，你應該在按下標籤時調用地圖的功能..所以地圖創建時該標籤是可見的.. – scaisEdge
