我使用下面的代碼來顯示保存在MySQL數據庫中的每個位置的標記。谷歌地圖邊欄

我現在希望能夠通過添加一個側邊欄擴展頁遠一點的功能，因此如果用戶點擊側邊欄的位置，它凸顯了選擇黃色背景和然後將地圖拖到相關標記的中心，在此處打開信息窗口。如果用戶點擊標記，我想要打開信息窗口並且側欄上的相關位置再次以黃色背景突出顯示。
我一直在研究這一段時間，我發現我想在這裏的側欄的確切類型http://econym.org.uk/gmap/example_map2c.html但問題是，這是在谷歌地圖API的v2。
我只是想知道是否有人可能會請我看看我需要做些什麼來完成這項工作。

嗨，非常感謝您花時間回覆我的帖子。我已經看過Google網站上的文檔以及通過在互聯網上搜索的許多示例，儘管從初學者的角度來看，我發現有點難以理解，這就是我來到這裏的原因。親切的問候。 Chris – IRHM
嗨，我想知道有人能否幫助我。我已經找到了我希望在本論壇上解決我的問題的方法：http://stackoverflow.com/questions/4904549/open-infowindow-of-specific-marker-from-outside-google-maps-v3。我已經修改了這個以適合我的數據，顯示爲我原始文章的更新。然而，當我運行這個時，我收到以下錯誤'對象預期在第33行字符7.我檢查了這與原始，我找不出問題是什麼。有人可能請看看這個，看看我哪裏出錯了。非常感謝和問候克里斯 – IRHM
