JavaScript 支持 ​

JavaScript 的诞生旨在将 Web 页面上的相关处理从服务器端转移到客户端，从而构建更具交互性的 Web 应用。福昕 PDF SDK JavaScript 扩展了 JavaScript 语言，通过引入新的对象及其相关的方法和属性，使得开发者能够在 Web 环境中直接操作 PDF 文档。利用这些扩展，开发者可以管理文档安全性、与数据库进行通信、处理文件附件以及进行各种 PDF 文件操作，从而实现交互式 Web 表单等功能。

JavaScript Action

JavaScript action 是一种特殊的动作类型，它包含一段由 JavaScript 解释器编译和执行的脚本。在福昕 PDF SDK 的 Java 开发环境中，com.foxit.sdk.pdf.actions.JavaScriptAction 类继承自 Action 类，并提供了一系列接口用于获取和设置 JavaScript action 的相关数据。

支持列表

您可以在 JavaScript支持列表 中查看福昕 PDF SDK 所支持的 JavaScript 方法和属性的完整列表。
