jQWidgets jqxTreeGrid aggregatesHeight属性用法及代码示例

小工具是一个 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、经过优化、独立于平台且得到广泛支持的框架。 jqxTreeGrid 用于表示 tree-like 结构中的数据。此小部件可用于显示分层数据的 multi-column、数据分页、排序和过滤、数据编辑、列大小调整、固定列、条件格式、聚合和行选择。这些小部件还从任何类型的数据源(例如 XML、JSON、Array、CSV 或 TSV)读取和显示数据。

aggregatesHeight 属性用于设置或获取指定 jqxTreeGrid 的聚合条的高度。此处聚合条只有在将 showAggregates 属性的值设置为 true 后才可见。

用法:

用于设置 aggregatesHeight 属性：

$('#treeGrid').jqxTreeGrid({aggregatesHeight:30});

获取 aggregatesHeight 属性：

var aggregatesHeight = 
    $('#treeGrid').jqxTreeGrid('aggregatesHeight');
