  10          * This is a way of getting simple feedback from users. It's useful
  11          * for testing new features -- users can give you feedback without
  12          * the difficulty of opening a whole new talk page. For this reason,
  13          * it also tends to collect a wider range of both positive and negative
  14          * comments. However you do need to tend to the feedback page. It will
  15          * get long relatively quickly, and you often get multiple messages
  16          * reporting the same issue.
  17          *
  18          * It takes the form of thing on your page which, when clicked, opens a small
  19          * dialog box. Submitting that dialog box appends its contents to a
  20          * wiki page that you specify, as a new section.
  21          *
  22          * Not compatible with LiquidThreads.
  23          *
  24          * Minimal example in how to use it:
  25          *
  26          *     var feedback = new mw.Feedback();
  27          *     $( '#myButton' ).click( function () { feedback.launch(); } );
  28          *
  29          * You can also launch the feedback form with a prefilled subject and body.
  30          * See the docs for the #launch() method.
  31          *
  32          * @class
  33          * @constructor
  34          * @param {Object} [options]
  35          * @param {mw.Api} [options.api] if omitted, will just create a standard API
  36          * @param {mw.Title} [options.title="Feedback"] The title of the page where you collect
  37          * feedback.
  38          * @param {string} [options.dialogTitleMessageKey="feedback-submit"] Message key for the
  39          * title of the dialog box
  40          * @param {string} [options.bugsLink="//bugzilla.wikimedia.org/enter_bug.cgi"] URL where
