在AEM pathBrowser中限制文件类型的方法

我需要在使用touchUI字段时限制文件类型

granite/ui/components/foundation/form/pathbrowser

pathfield有一个功能

正则表达式：/（png | jpg | jpeg）$/， regexText:“请选择正确的文件”

它不适用于pathBrowser，TouchUI字段

有什么建议吗？

我在OSGI bundle包上创建了一个谓词类，它限制了文件类型。java类

@Component(label = "Dam Image Predicate",
description = "This predicate is used to display only JPG and PNG files in the pathfield")
@Service(value = Predicate.class)
@Properties({@Property(label = "Predicate Name", name = "predicate.name", value = "damimagepredicate",
propertyPrivate = true)})

                    if(null!=primaryType && !primaryType.isEmpty()){
                        if(primaryType.equalsIgnoreCase(REP_ACL)){

您可以在TouchUI组件中执行客户端限制，以限制用户发布其他类型的文件。我不建议为您的用例创建类似的东西。客户端的限制是“regex”，这也仅适用于经典UI。对于TouchUI，我没有找到任何这样的解决方案。如果有的话，请建议我@RajeshPantula您可以在TouchUI组件中执行客户端限制，以限制用户发布其他类型的文件。我不建议为您的用例创建类似的东西。客户端的限制是“regex”，这也仅适用于经典UI。对于TouchUI，我没有找到任何这样的解决方案。如果有的话，请建议我@拉杰什潘图拉
