jQWidgets jqxGrid verticalscrollbarlargestep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。 jqxGrid 用于演示以表格形式显示数据的 jQuery 小部件。此外，它还全面支持数据连接、分页、分组、排序、过滤和编辑。

Verticalscrollbarlargestep 属性用于设置或获取滚动条的大步长。此外，此属性定义了每当用户点击滚动条拇指上方或下方的部分时修改垂直滚动条的值的步骤。它是数字类型，默认值为 400。

用法:

设置垂直滚动条大步长属性。

$('#Selector').jqxGrid({ 
    verticalscrollbarlargestep: 300
});

返回垂直滚动条大步长属性。

var verticalscrollbarlargestep = $('#Selector')
    .jqxGrid('verticalscrollbarlargestep');
