javascript filetype "fold"


    Feb 23 2006 | 10:27 pm
    hello,
    i learned from the js example "jsfolderiter.js" that a File object's type would be "fold" if the file is a directory. However, i'm finding that i get a blank filetype for folders. I'm also noticing that .xml files return a blank filetype where as according to "max-fileformats.txt" they should return TEXT.
    js is attached.
    please put some .txt, a .pat, and/or a .xml in your root folder to test it out.
    patch is below.
    thanks,
    ali

      No js was provided. As always, please also provide detailed system
      and max versions, and specific usage with any report.

      weird, i'm using the web-interface for the forum and was pressing on "upload file" after choosing the file.
      perhaps that's not the thing to do.. let's try again.
      max 4.5.6, os x 10.4.5
      just in case, here's the js:
      ____________
      var filelist = new Array();
      function foldercontents(mypath)
      {
      //post(mypath,"n");
      var myfolder = new Folder(mypath);
      // myfolder.reset();
      filelist = new Array();
      var counter = 0;
      while (!myfolder.end) {
      post(myfolder.filename);
      post();
      filelist[counter]= new File(myfolder.filename);
      var thisfile = new File(myfolder.filename);
      post("file type is: ",thisfile.filetype);
      post();
      counter = counter + 1;
      myfolder.next();
      }
      myfolder.close();
      }
      function getfile(n)
      {
      post("file name: ",filelist[n].filename);
      post();
      post("file type: ",filelist[n].filetype);
      post();
      post("folder path: ",filelist[n].foldername);
      post();
      }

      Okay. Please note that you're not following the jsfolderiter
      example,l which clearly demostrates that the filetype tested is an
      attribute of the *Folder* object rather than the *File* object. I
      believe this should solve your problems. You cannot open a folder as
      a file.
      In general, I would recommend whenever you have a problem like this,
      scrutinizing the differences between the working example and your
      file. C'mon Ali, I know you can spend a little more time before
      getting us involved. :)

      i understand. thanks.
      a small followup question,
      if i pass an object (of class File or a Folder, i.e. created with "new File() or new Folder()") to a function, how can i test in that function to see if the passed object is a File or a Folder?

      Check out the object.isPrototypeOf() method:
