Question

While just a little issue, based on the doc, I should be able to create a re-usable block. It could be my lack of Scala experience juicing me here…

I have a List of Strings that get passed to the .scala.html file. The strings are javascript file references without the “.js”.

@jsFileWithExtension(file: String) = @{
  val newFile = file + ".js
}
@for(jsFile <- headJs) {
   <script src="/assets/javascripts/@jsFileWithExtension("@jsFile")"></script>
}

It’s currently loading the jsFile without the extension.

Answer 1

Try this:

@jsFileWithExtension(file: String) = @{ file + ".js" }


@for(jsFile <- headJs) {
   <script src="/assets/javascripts/@jsFileWithExtension(jsFile)"></script>
}

Your jsFileWithExtension needs to return a value. Right now it returns Unit. Then as Daniel pointed out the parameter to the function does not need the quote or magic @ char.
