阻止整個頁面

當我更改頁面（頁面1到頁面2）時存在一些延遲，並且可以單擊其他按鈕並執行這些操作。所以我想在加載下面這個頁面的等待時間內阻止頁面，我該怎麼辦？阻止整個頁面

我使用jsf2和primefaces。

此時已經測試blockUI和blockUI的擴展 - >不行

你介意給我們提供一些代碼？你有沒有試過這個http://stackoverflow.com/questions/20198898/how-to-target-entire-jsf-page-to-be-blocked-by-pblockui-peblockui？ – Leo 2014-10-10 17:12:10

此時已經測試過blockUI和blockUI-extensions - >不行 – Marin 2014-10-10 17:14:42

這裏關注的是如何在頁面存在兩頁之間時移動頁面 – Marin 2014-10-10 17:16:49

你應該告訴我們。爲什麼p:blockUI不工作？

試試這個。這是工作。
