如何在 HTML 到 PDF 使用 C# 中使用 Java Script

In this tutorial, we explore the process of generating PDFs using JavaScript and HTML in a .NET application with the IronPDF library. The first step involves ensuring the IronPDF NuGet package is installed in your project. You then import the IronPDF namespace and set the license key. Begin by preparing an HTML string that includes JavaScript code, such as writing text to the document. Instantiate the Chrome PDF renderer and enable JavaScript with appropriate rendering options, including setting execution wait times. Render the HTML to a PDF document and save it using the 'Save As' method. For more advanced manipulation, execute custom JavaScript to alter HTML elements, such as changing color, and save the modified PDF. To handle JavaScript errors, set up a message listener to log console messages, including uncaught type errors. For visualization, use external libraries like d3.js and c3.js to render charts within PDFs. Finally, run the application and verify the generated PDFs, demonstrating the versatility of IronPDF. This guide encourages exploring IronPDF's advanced functionalities for document generation tasks. Sign up for a trial on the Iron Software site to experience the software firsthand.
