添加 Javascript 动作 PDF

PdfContentEditor 类位于 Aspose.Pdf.Facades 包下，提供了向 PDF 文件添加 Javascript 动作的灵活性。您可以创建一个链接，使用与在 PDF 查看器中执行菜单项相对应的序列动作。此类还提供为文档事件创建附加动作的功能。

首先，在 Document 中绘制一个对象，在我们的示例中是一个 Rectangle。并将动作 createJavaScriptLink 设置为矩形。之后，您可以保存文档。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddJavascriptAction()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    using (var editor = new Aspose.Pdf.Facades.PdfContentEditor())
    {
        // Bind PDF document
        editor.BindPdf(dataDir + "sample.pdf");

        // Create Javascript link
        var rect = new System.Drawing.Rectangle(50, 750, 50, 50);

        var code = "app.alert('Welcome to Aspose!');";
        editor.CreateJavaScriptLink(code, rect, 1, System.Drawing.Color.Green);

        // Save PDF document
        editor.Save(dataDir + "JavaScriptAdded_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddJavascriptAction()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    using var editor = new Aspose.Pdf.Facades.PdfContentEditor();

    // Bind PDF document
    editor.BindPdf(dataDir + "sample.pdf");

    // Create Javascript link
    var rect = new System.Drawing.Rectangle(50, 750, 50, 50);

    var code = "app.alert('Welcome to Aspose!');";
    editor.CreateJavaScriptLink(code, rect, 1, System.Drawing.Color.Green);

    // Save PDF document
    editor.Save(dataDir + "JavaScriptAdded_out.pdf");
