我正在使用下面的代碼將HTML列表鏈接到地圖上的標記。當我點擊標記時,InfoWindow可以毫無問題地打開。但是,當我點擊列表項時,儘管地圖正確擺放並居中於適當的標記,但我無法同時打開InfoWindow。無法在地圖上打開Infowindow Pan

你已經綁定上的標記的點擊事件,打開信息窗口。你想要做的就是觸發點擊,就好像用戶自己做了一樣。

事情是這樣的:

google.maps.event.trigger(marker, 'click'); 

困難的部分將是您識別標記的點擊事件開火。建議你有一個所有標記的數組。在您調用scrollToMarker的同時,還要執行此觸發器,並通過索引參數來確定陣列中哪個標記要「點擊」。

更新:好的,下面是一個工作示例我的意思是。我已經刪除了您的Ajax請求部分並添加了一些虛擬標記數據,但它應該足夠簡單,以便您瞭解如何集成到您的代碼中。

嗨,非常感謝您的幫助。原諒我,當談到這一點時,我有點新手,但是我應該採取這個正確的方向? map.panTo(point); 函數bindInfoWindow(marker,map,infoWindow,html)google.maps.event.addListener(gmarkers,'click',function(){ infoWindow.setContent(html); infoWindow.open(map,gmarkers); }); } } 親切的問候。 Chris – IRHM

不完全;我會看看我是否可以稍後發佈一個工作示例 – duncan

嗨Duncan,對代碼的誠摯感謝。我在這裏非常密集,但我無法得到它的工作。我試圖包括鏈接我的PHP文件,但得到以下錯誤對象預計行28字符7指向此行: downloadUrl(「loadmylocations.php」,函數(數據){ 我已更新我的原始文章顯示我修改code.I只是想知道你是否可能請看看這個,讓我知道我要去哪裏錯了,我想這可能是因爲我試圖爲每個不在那裏的標記獲取屬性,但我可以好的問候Chris – IRHM
