jQWidgets jqxDataTable source属性用法及代码示例


jQWidgets是一个 JavaScript 框架,用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大、优化、独立于平台且得到广泛支持的框架。这jqx数据表用于读取和显示 HTML 表中的数据。它还用于显示来自各种数据源(例如 XML、JSON、Array、CSV 或 TSV)的数据。

source属性用于指定显示的jqxDataTable的数据源。该属性旨在指向 jqxDataAdapter 的原型。此外,为了删除数据源,需要将此属性设置为 null。它是Object类型,默认值为null。

用法:

设置源属性。

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

返回资源属性。

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

链接文件:下载jQWidgets从给定的链接。在 HTML 文件中,找到下载文件夹中的脚本文件。
