我如何选择我想要保存下载文件的位置？ [英] How can I choose the location where I want to save downloaded files?

问题描述

我在Groovy下有一个Grail应用程序。我导出一个Excel文件。如果我在代码中提到文件位置，我可以导出文件，但我想让用户在他的PC上选择文件位置。什么是HTML或JavaScript来做到这一点？您有任何代码可以帮助我吗？

谢谢。

  response.setHeader（Content-disposition，attachment; filename = book.csv）; 
 response.setContentType（application / vnd.ms-excel）; 
 response.outputStream<< test.writeToString（）;
