通過網址無法顯示谷歌地圖熱圖圖層

我一直在嘗試與谷歌地圖javascript api v3一起使用熱圖層。我可以創建一個加載地圖和熱圖層的html頁面，並從我的本地機器打開它，它可以正常工作。但是，當我嘗試通過url打開相同的頁面時，地圖會呈現，但熱圖圖層不會。這裏是我試圖加載的HTML ...通過網址無法顯示谷歌地圖熱圖圖層

您還有其他信息嗎？指向展現問題的地圖的鏈接或jsfiddle？ – geocodezip

如果你編輯你的問題來添加它，它可能會是最簡單的。 – geocodezip

我無法提供鏈接，因爲它位於防火牆後面的開發環境中。我生成的頁面就像谷歌的網站上給出的例子一樣，並且在這兩種情況下地圖都會加載，但是當通過網址拖動時，圖層不會加載。 – user1630869
