Scala-liftweb框架

我有两个复选框，在提交时我想让用户下载两个不同的文件，我该怎么做？我需要帮助，因为我无法获得任何有关这方面的在线资料。我不熟悉这个框架

这就是我到目前为止所尝试的

def render = {
 def onSubmit1() : LiftResponse = {
       val userInput1 = S.param("getit").openOr("")
      val userInput2 = S.param("getit2").openOr("")
      val checkbox1 = S.param("yes").openOr("")
      val checkbox2  = S.param("yes").openOr("")
val fileToDownload = funFile(as, art, top)
       val fileName = "My File" 
 if (fileToDownload.equals()) {
         return S.redirectTo("/Somewhere")
       } else {
         InMemoryResponse(
          fileToDownload.mkString("\n").getBytes("UTF-8"),
            "Content-Type" -> "text/plain; charset=utf8" ::
             "Content-Disposition" -> s"attachment; filename=$fileName" :: Nil,
           cookies = Nil, code = 200)
       }
"#submitButton" #> SHtml.onSubmitUnit(onSubmit1)

我找到了一种方法，就是使用这个函数压缩这两个文件 ,

我想你必须通过javascript来完成我想你必须通过javascript来完成

if (checkbox1.getOrElse("") == "checked" && checkbox2.getOrElse("") == "checked") {
val checkboxIterable1: Iterable[String] = filegetter1
        val checkboxFile1 = new File("checkboxFile1.csv")
        using(new FileWriter(checkboxFile1))(writer =>
          fileGetter1.foreach { d =>
            writer.write(d)
          })
       fileGetter1

        val checkboxIterable2: Iterable[String] = fileGetter2
        val checkboxFile2 = new File("checkboxFile2.csv")
        using(new FileWriter(checkboxFile2))(writer =>
          fileGetter2.foreach { d =>
            writer.write(d)
          })
        fileGetter2

        val zipFile = zip("Zipped file", List("checkboxFile1.csv", "checkboxFile2.csv"))
        val zipFileName = "Zipped file"

        val zipToBArray = new BufferedInputStream(new FileInputStream(zipFileName))
        val getByteArray = Stream.continually(zipToBArray.read).takeWhile(-1 !=).map(_.toByte).toArray

        InMemoryResponse(
          getByteArray,
          "Content-Type" -> "application/zip; charset=utf8" ::
            "Content-Disposition" -> s"attachment; filename=file.zip" :: Nil,
          cookies = Nil, code = 200)
      }
