从WinJS应用程序打开PDF文件
问题描述：
我有一个应用程序，用户可以在其中单击一个按钮，并应向其显示存储在该应用程序中的PDF.
I've got an application in which the user clicks a button, and should be presented a PDF that is stored in the application.
他们可以在应用程序内部查看PDF，也可以启动本机Windows PDF查看器.
They can view the PDF internally in the app, or launch the native windows PDF viewer, either way is fine.
如何为单击按钮以启动PDF文件视图提供链接/事件处理程序?
How can I provide a link / event handler for the button click to launch a view of a PDF file?
答
说明:使用指定的选项启动与指定文件关联的默认应用.
description: Starts the default app associated with the specified file, using the specified options.
示例代码:
Windows.System.Launcher.launchFileAsync(file, options).done( /* Your success and error handlers */ );
