A parameterized dialog with an autoclose function

[centurianii]

I found similar behavior in other projects so I decided to add it here too as a bonus! My comments follow the rules of jsDoc node plugin.

Here it is the code:

/**
 * @summary
 * MyClass.prototype.dialog
 * ------------------------
 * @desc
 * A prototype method of **`MyClass`**.
 * 
 * It handles dialog setup during {@link MyClass#myCommand} command.
 * 
 * It builds a parametric dialog of type:
 * - alert or,
 * 
 * - confirm.
 * 
 * It also adds a time counter at the cancel button that counts down and closes
 * the dialog automatically.
 * 
 * The passed callback is executed by the `OK` button which has also a 
 * parameterized label.
 * 
 * Alerts do not have the `OK` button, see property `hideOk`.
 * @function MyClass#dialog
 * @param {Object} params An object as a named argument list
 * @prop {String} size Dialog's size, [size-small|size-normal|size-wide|size-large]
 * @prop {String} type Dialog's type, 
 *    [type-default|type-primary|type-info|type-success|type-warning|type-danger]
 * @prop {String} title Dialog's title
 * @prop {String} message Dialog's message
 * @prop {Integer} count Number of seconds that the dialog will be open
 * @prop {Boolean} hideOk Controls appearance of dialog's ok button
 * @prop {String} okLabel Dialog's label for ok button
 * @prop {Function} okAction Dialog's function to be called on pressing the ok button
 * @return {MyClass} The `MyClass` object

dialog: function(params){
   var dialog,
       cancel,
       time;
   
   // auto-close function, it counts down from 'time.start'
   time = {
      start: params.count,
      elem: null,
      html: '',
      count: function(elem){
         if(elem){
            time.elem = $(elem);
            time.html = time.elem.html();
         }
         time.elem.html(time.html + ' (' + time.start + ')');
         --time.start;
         if(time.start > 0)
            setTimeout(time.count, 1000);
         else
            dialog.close();
      }
   };

   cancel = dialog.getButton('cancel');
   //cancel.spin();
   time.count(cancel);

      dialog.getButton('ok').addClass('hide');
   else
      dialog.getButton('ok').removeClass('hide');
   dialog.open();
