极客教程jQWidgets jqxDataTable initRowDetails属性
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、并被广泛支持的框架。jqxDataTable是用来读取和显示HTML表数据的。这也被用来显示来自各种数据源的数据，如XML、JSON、Array、CSV或TSV。
initRowDetails属性是一个回调函数，有助于初始化扩展行的细节。每当显示的jqxDataTable的任何行在开始时被扩展，它只被调用一次。它是函数类型，其默认值为空。
这里使用的参数列表如下。
- id/key。它说明了扩展行的id/key。
- dataRow：它是以Key/Value对的形式表示的扩展行的数据。
- element。它是作为jQuery选择器的行的详细信息的陈述HTML元素。
- rowInfo：它是陈述对象，有助于修改行的细节高度。
语法:
设置initRowDetails属性。
$('Selector').jqxDataTable({ initRowDetails: null });
返回initRowDetails属性。
var initRowDetails =
$('Selector').jqxDataTable('initRowDetails');
