我傾注了每個問題在本網站上詢問有關填充jqGrid摘要頁腳沒有用戶數據是服務器請求。和jqGrid維基資源，只是找不到答案。這可能嗎？jqGrid摘要頁腳可以填充沒有userdata服務器請求？
我以許多典型的方式使用jqGrid作爲我的管理門戶的一部分，但有一個特定的用途，我希望外觀&覺得jqGrid最初是一個空UI容器，用於某些用戶交互，一種不會在提交上發佈的表單（感謝下面Oleg的偉大腳本），但只是添加行並使用新添加行中的值更新摘要頁腳。在grid選項中，我有'summary'：colModel中的「sum」，「grouping：true」，footerrow：true，userDataOnFooter：true，altRows：true，但除了由本地數據字符串中的userdata提供的初始值總結頁腳值從不改變。似乎沒有人想要觸及這個主題。是否因爲jqGrid的主要特性是數據庫驅動功能？我在它的數據庫驅動的立場中使用了大約15個jqGrid實例（其中許多現在位於生產服務中），但爲了一致性（我所有的UI都在jqTabs內）需要使用它，最初作爲客戶端UI，沒有服務器請求（所有的東西都會在以後保存到db），但是我只是拉着我的頭髮試圖在客戶端和客戶端上編程操作彙總頁腳。任何人都可以建議如何增加一個新的行添加新行的值，其中的值將與任何現有行彙總，哪些不涉及任何發佈到服務器，只是在網格內更新？
提供的代碼很長，主要基於用戶Oleg的解決方案，用於從模式表單添加一行而不發佈到服務器。我已經將本地數組數據更改爲JSON字符串，只是爲了更好地理解符號，因爲我習慣於使用xml。 jsonstring使用一個默認行初始化網格供用戶編輯。我遺漏了jsonReader，因爲網格不會與它一起渲染。
簡而言之，我想要做的是在將新行添加到網格時（不會發布到此時發生的服務器）或編輯或刪除，更新摘要頁腳。當達到某一組值時，用戶會看到一個顯示的按鈕，將行數據保存到數據庫。

參考關於用戶數據的Stackoverflow用戶@Oleg（http://stackoverflow.com/questions/3128837/json-and-jqgrid-what-is-user-data）這是說：_A標準的JSON閱讀器是定義如此，它從所發送數據的根讀取數據userdata屬性並保存。這個數據可以通過以下方式訪問：_' var myUserData = jQuery（「grid_id」）。getGridParam（'userData'）;'Question然後'userdata'可以在jsonReader初始讀取之後被修改和檢索（在本例中使用json ），如果是這樣，那麼本地修改的'userdata'如何顯示在摘要頁腳？ – 2011-04-12 07:36:15
