jQWidgets jqxTreeGrid pagerButtonsCount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jqxTreeGrid用于表示tree-like结构中的数据。该小部件对于显示多列分层数据、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、聚合和行选择非常有用。这些小部件还可以读取和显示来自任何类型数据源(例如 XML、JSON、Array、CSV 或 TSV)的数据。

寻呼机按钮计数属性用于设置或获取指定jqxTreeGrid的Pager上显示的按钮的数量。当pagerMode设置为“default”时，该属性有效。

用法:

用于设置寻呼机按钮计数属性：

$('Selector').jqxTreeGrid({pagerButtonsCount: 3 });

为了得到寻呼机按钮计数属性：

var pagerButtonsCount = 
    $('Selector').jqxTreeGrid('pagerButtonsCount');
