jQWidgets jqxDataTable serverProcessing屬性用法及代碼示例


jQWidgets是一個 JavaScript 框架，用於為 PC 和移動設備製作基於 Web 的應用程序。它是一個非常強大、優化、獨立於平台且得到廣泛支持的框架。這jqx數據表用於讀取和顯示 HTML 表中的數據。它還用於顯示來自各種數據源(例如 XML、JSON、Array、CSV 或 TSV)的數據。

serverProcessing 屬性用於設置或返回是否使用服務器管理排序、過濾和分頁，並且顯示的 jqxDataTable 向服務器方向傳遞 Ajax 請求並顯示返回的數據。此外，如果當前頁麵、頁麵大小、排序列或排序順序發生更改，則 jqxDataTable 將自發執行新的數據綁定以及更改的參數。它是布爾類型，默認值為 false。

jqxDataTable默認發送到服務器的數據列表如下：

  • sortdatafield:它是已排序列的指定數據字段。
  • sortorder:這是規定的排序順序。
  • pagenum:它是顯示數據表的指定頁碼。
  • pagesize:它是顯示數據表的指定頁麵大小。
  • filterscount:它是應用於顯示的 jqxDataTable 的過濾器的計數。
  • filtervalue:它是過濾器的規定值。
  • filtercondition:這是過濾器的規定條件。過濾器的條件可以是“CONTAINS”、“DOES_NOT_CONTAIN”、“EQUAL”、“EQUAL_CASE_SENSITIVE”、NOT_EQUAL”、“GREATER_THAN”、“GREATER_THAN_OR_EQUAL”、“LESS_THAN”、“LESS_THAN_OR_EQUAL”、“STARTS_WITH” 、“STARTS_WITH_CASE_SENSITIVE”、“ENDS_WITH”、“ENDS_WITH_CASE_SENSITIVE”、“NULL”、“NOT_NULL”、“EMPTY” 或 “NOT_EMPTY”。
  • filterdatafield:它是過濾器列的指定數據字段。
  • filteroperator:它是過濾器的指定運算符，其中 0 用於“AND”，1 用於“OR”。

用法:

  • 設置服務器處理屬性。
$('Selector').jqxDataTable({ 
serverProcessing: true,
});
  • 返回服務器處理屬性。
var serverProcessing = 
$('Selector').jqxDataTable('serverProcessing');
