jQWidgets jqxDataTable addRow()方法

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。它是一个非常强大的、优化的、与平台无关的、被广泛支持的框架。jqxDataTable是用来读取和显示HTML表的数据的。这也被用来显示来自各种数据源的数据,如XML、JSON、Array、CSV或TSV。

addRow()方法用于在现有的数据表中添加一个新的行。关于与服务器的同步,也请看jqxDataAdapter插件的帮助文档。

$("#dataTable").jqxDataTable('addRow', 
    rowIndex, rowData, rowPosition);

  • rowIndex。这是该行的指定索引。这是数字类型的。
  • rowData。这是指定的行数据。这是一个对象的类型。
  • rowPosition。这是给定的行位置。它是字符串类型的,它的值是 “最后 “和 “第一”。默认情况下,使用 “最后”。
