如何在制表器中过滤树结构中的子级？

Question

我尝试在Tabulator树结构上调用setFilter函数，以过滤出项目。似乎只过滤掉顶级父母。知道如何使这项工作适用于任何级别（任何孩子或父母）吗？ http://tabulator.info/docs/4.1/tree并没有过多说明过滤的工作原理。

功能

table.setFilter('id', '=', 214659)没有返回任何内容...

树结构

Answer 1

经过一番搜索后，发现了名为lodash的deepdash库的扩展，该扩展具有深层过滤，并且效果很好。

您将有2个新的依赖项，但我认为它将满足您的目的。查看有关如何安装它们的文档here

在此处的代码段中，您可以在日志中查看结果。我也做了一个沙箱here

这是一个或多个ID的列表。

如果只需要一个值，则更改条件。 return _.indexOf(idList, value.id) !== -1;至return id===value.id;，其中id是您的id变量

此外，在查看Tabulator的文档后，它只有一个级别的过滤器，即使您编写自己的自定义过滤器也无济于事，因为它期望布尔值显示或不显示行。但仅针对第一级，因此如果父母不是您要找的孩子，它将被忽略。您唯一的选择是在制表符之外过滤数据。
