我已經創建了一個簡單的網格，通過php從服務器檢索數據。 MYSQL數據庫中的行數爲9.
我決定將rowNum選項從rowNum：10更改爲rowNum：7，看看會發生什麼。正如我預料的那樣，網格上出現了7行。問題是我看不到其餘的2.尋呼機欄沒有第二頁（它說的第1頁，共1頁）。
然後我添加recordtext選項並將其設置爲此記錄文本：{{}}的{0} - {1}。 刷新頁面，並在網格的右下角這個文本apeard「1 - 7 of 9」。這意味着從服務器返回的所有數據，但分頁有些不好。jqgrid分頁欄不顯示所有頁面
讓我發佈代碼。

此外試圖使用this方法也沒什麼改變。 有什麼想法？你能給我一些提示嗎？
在此先感謝。
