数据排序

SpreadJS可以按升序或降序对数据进行排序。可以选择表单区域并通过上下文菜单排序,也可以通过表格的表头筛选框进行排序。同时,也可以通过调用表单的sortRange方法进行排序。在一些特定的场景中,传统的升序或降序排序无法满足需求,SpreadJS提供了可定制的compare函数来进行排序。如下代码所示。

使用sortRange方法可以对指定区域进行排序,如下所示: 用户也可以使用上下文菜单排序项或过滤框中对数据进行排序。 不同数据的排序优先级为:布尔 > 字符串 > 数值,例如 True > 'A' > 8. 自定义排序 用户可以使用回调函数定义自定义的compare方法进行排序。 以下代码显示了如何使用localCompare进行排序。 根据单元格颜色排序 用户可以通过给定sort info使单元格根据单元格的颜色排序。这个功能支持纯色填充,图案填充和渐变填充。 以下代码显示了如何使用背景颜色进行排序。 根据字体颜色排序 用户可以通过给定sort info使单元格根据单元格的字体颜色排序. 这个功能仅支持纯色填充。 用户可以定义引发RangeSorting事件时使用的回调函数。 Group sort 你可以使用groupSort函数来设置是否将数据分组,GroupSort提供以下的方式: flat:排序忽略分组 group:仅在组与组之间排序,组内不进行排序 child:只在组内排序 full:排序时移动组,并且对组内部进行排序 下面的代码展示了组排序选项。 用户可以定义在RangeSorting事件发生时要使用的groupSorting选项。 排序忽略隐藏部分 你能够设置当排序时是否要忽略被隐藏的值, 当ignoreHidden设置为true, spread会跳过并且不移动被隐藏的值。 当ignoreHidden设置为false, spread会比较并移动被隐藏的值。 当groupSort设置为group/child/full, SpreadJS会移动被隐藏的值并且移动行/列的可见性并隐藏值。 下面的代码会展示使用ignoreHidden选项. 用户可以定义RangeSorting事件发生时要使用ignoreHidden选项。 默认情况下,如果排序范围包括组,SpreadJS将使用group排序对数据进行排序。否则,它将使用flat排序并且忽略隐藏。 保持上次的排序状态 最后一次排序操作设置将由worksheet进行记录,您可以使用getSortState函数获取最后一次排序状态。 下面的代码展示了如何使用getSortState方法. 现在,您可以在不传递任何参数的情况下调用sortRange来触发重新排序,重新排序操作基于最后一次排序状态。 用户可以使用bind函数联合sortRange来实现自动排序。以下是一个简单的代码示例: 上述代码将在工作表中的值发生更改时自动调用,因此每当您在工作表中更改值时,将触发重新排序操作。
