jQWidgets jqxTreeGrid exportSettings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。

導出設置屬性用於設置或返回每當調用exportData方法時顯示的jqxTreeGrid使用的數據的導出設置。是object類型，默認值如下

{ 
      columnsHeader: true, 
      hiddenColumns: false,
      serverURL: null, 
      characterSet: null, 
      collapsedRecords: false, 
      recordsInView: true, 
      fileName: "jqxTreeGrid"
}

參數：

  • columnsHeader:它用於確定是否導出列標題。
  • hiddenColumns:它用於確定是否導出隱藏列。
  • serverURL:它用於確定服務器的 URL。
  • characterSet:它用於確定字符集。
  • recordsInView:它用於確定是否要導出所有記錄，或者還考慮過濾和排序。
  • fileName:它用於確定文件的名稱。

用法:

  • 設置導出設置 屬性。
$('Selector').jqxTreeGrid({ 
    exportSettings: { hiddenColumns: true }
});
  • 返回導出設置屬性。
var exportSettings = $('Selector').jqxTreeGrid('exportSettings');
