fr：资源模式下的自动完成不显示建议列表

Question

我使用 orbeon 表单生成器自动完成控件，我在编辑模式下更改了该控件以匹配自动完成资源模式的语法，如下所示：

当我在表单运行器中测试它时，我看到“fr-search-changed”事件被触发并且搜索值发生变化，但我看到没有填充项目集。 你能告诉我代码中有什么问题吗？ 我也确信该服务确实返回了我测试的结果

Answer 1

我无法完全运行您的代码，因为它没有指向可访问的服务，但我怀疑自动完成 资源模式 不适合您，因为该功能未在 3.9 版本中使用。为了能够使用资源模式，您需要使用较新的版本（在撰写本文时尚未发布）或每晚构建。
