jQWidgets jqxDataTable initRowDetails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 Table 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。

initRowDetails 屬性是一個回調函數，有助於初始化展開行的詳細信息。每當顯示的 jqxDataTable 的任何行在開始時展開時，它僅被調用一次。它是Function類型，默認值為null。

這裏使用的參數列表如下：

  • id/ key ：它是擴展行的 id/key。
  • dataRow:它是擴展行的陳述數據，以鍵/值對的形式。
  • element:它是作為 jQuery 選擇器指定的行詳細信息的 HTML 元素。
  • rowInfo:它是有助於修改行詳細信息高度的指定對象。

用法:

設置 initRowDetails 屬性。

$('Selector').jqxDataTable({ initRowDetails: null });

返回初始化行詳細信息屬性。

var initRowDetails = 
    $('Selector').jqxDataTable('initRowDetails');
