    Question this

    What does this mean:

    element.multi_s elector = this;

    I is used in this javascript class:
    404 Error
    http://the-stickman.com/web-development/javascript/upload-multiple-files-with-a-single-file-element/


    I understand that this line is adding a reference to the object but can
    someone explain me why this is important and what is it used for?

      Alright I am going to venture out on a limb on this one, but I think it
      has something to do with closures.

      Or just in general having a spare to insert when 'this' is no longer in
      scope with the object you may be wanting.

      Then again my understanding of closures is about 20%.

          Ok thanks, i understand your explanation but can you give me an example or
          further explanation?

          The file in which this is used can be downloaded from
          http://the-stickman.com/files/multiple-file-element.zip and it is used in
          the file multifile.js at line 68
