jQWidgets jqxDataTable initRowDetails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 Table 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。

initRowDetails 属性是一个回调函数，有助于初始化展开行的详细信息。每当显示的 jqxDataTable 的任何行在开始时展开时，它仅被调用一次。它是Function类型，默认值为null。

这里使用的参数列表如下：

  • id/ key ：它是扩展行的 id/key。
  • dataRow:它是扩展行的陈述数据，以键/值对的形式。
  • element:它是作为 jQuery 选择器指定的行详细信息的 HTML 元素。
  • rowInfo:它是有助于修改行详细信息高度的指定对象。

用法:

设置 initRowDetails 属性。

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

返回初始化行详细信息属性。

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