jQWidgets jqxTreeGrid getCheckedRows()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。 jqxTreeGrid 用於表示 tree-like 結構中的數據。該小部件對於顯示多列分層數據、數據分頁、排序和過濾、數據編輯、列大小調整、固定列、條件格式、聚合和行選擇非常有用。這些小部件還可以讀取和顯示來自任何類型數據源(例如 XML、JSON、Array、CSV 或 TSV)的數據。

getCheckedRows() 方法用於返回指定 jqxTreeGrid 的所有已檢查行的平麵數組。

有一些保留的行成員：

checked:這是布爾值。這裏，返回該行的檢查狀態。
expanded:這是布爾值。此處，返回行的展開狀態。
icon: 這是字符串值。此處，返回該行的圖標 URL。
leaf: 這是布爾值。這裏，返回層次結構中行的葉子的存在性。
level:這是整數值。此處，返回行的層次結構級別。
parent: 這就是對象。對於根行，它返回 null，否則返回父行的對象。
records:這是一個數組。這裏，返回行的sub-rows集合。
selected:這是布爾值。此處，返回該行的選定狀態。
uid:這可以是數字或字符串值。此處，返回該行的唯一 ID 或鍵。

用法:

$('Selector').jqxTreeGrid('getCheckedRows');

Parameters: 該方法不接受任何參數。

返回值：此方法返回所有已檢查行的平麵數組
