我正在製作一張地圖，我想用數據庫中的值作爲javascript中的座標。請看下面：從mysql數據庫中檢索值作爲javascript中的值使用
我想通過從數據庫中獲取數據來改變經度和緯度的默認值，但我不知道如何。

請出示你的PHP代碼！ –
你說你正在製作地圖，但代碼只顯示一個功能。如果你可以用完整的代碼來完成這個問題，它將很容易幫助你。 –
我試圖發佈所有的代碼，但它不會允許我。它說錯誤。無論如何擴大我的問題。我想自定義緯度和經度的值，就像你在代碼的最後兩行看到的那樣。我設置的值有默認值。我想要的是從數據庫中獲取價值。應該獲取數據庫中的任何其他輸入，並且應該創建一個循環來創建上面類似代碼的新行（最後兩行）。我希望我有道理:)謝謝！ – jack
