jQWidgets jqxDataTable showAggregates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。 jqxDataTable 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。

showAggregates 屬性用於檢查指定 jqxDataTable 的聚合欄是否可見。該屬性有兩個可能的值：“true” 和“false”。

用法:

用於設置顯示聚合屬性：

$('#dataTable').jqxDataTable({showAggregates: true});

為了得到顯示聚合屬性：

var showAggregates = 
    $('#dataTable').jqxDataTable('showAggregates');
