如何通过Chrome扩展程序显示“文件另存为”对话框？

Question

I'm creating an extension for Google Chrome that converts a webpage into a PDF file. From the JavaScript background page, the URL, DOM, and the path are passed to the NPAPI DLL, where the conversion happens. For now, the path is hard-coded. I want to add a File Saveas dialog to the extension, and grab the path from it, with the file name, and pass it to the NPAPI DLL. What should I do?

Answer 1

Why would you do the file save-as dialog in the extension if you are just going to have it pass to the NPAPI dll? If it were me I'd just have the NPAPI dll pop up the save dialog.
