How do i get widget instance inside a jQuery widget?

I'm working on a keyboard widget for a project, i'm extending $.ui.mouse. I need click behavior (not triggered by _mouseCapture). I'm having difficulties to get back this.options inside it. See code blocks below :

$.widget("ui.keyboard", $.ui.mouse, {
    widgetEventPrefix: "keyboard",
    options: {
        [...]
    },
    [...],
    _create : function() {
        this.element.bind('click.'+this.widgetName, this._mouseClick);
    },
    _mouseClick: function(e) {
        // how do i get this.options here
    }
});

Is it best to do this :

$.widget("ui.keyboard", $.ui.mouse, {
    widgetEventPrefix: "keyboard",
    options: {
        [...]
    },
    [...],
    _create : function() {
        var self = this;
        this.element.bind('click.'+this.widgetName, function(e) { self._mouseClick(e, self); });
    },
    _mouseClick: function(e, self) {
        // how do i get this.options here -> self.options
    }
});

Or this :

$.widget("ui.keyboard", $.ui.mouse, {
    widgetEventPrefix: "keyboard",
    options: {
        [...]
    },
    [...],
    _create :开发者_高级运维 function() {
        this.element.bind('click.'+this.widgetName, this._mouseClick);
    },
    _mouseClick: function(e) {
        var self = $.data(this, "keyboard");
        // how do i get this.options here -> self.options
    }
});

I had trouble with the last one when i try to trigger it manually $.data is not up unless i trigger a click on this.element (which is quite logic).

Is there some other ways ? Which one is the best to pick ?

Thanks,

You could call an anonymous function returning an object, like this:

$.widget("ui.keyboard", $.ui.mouse, function(){
  var self;

  return {
    widgetEventPrefix: "keyboard",
    options: {
      [...]
    },
    _create : function() {
      self = this;
      this.element.bind('click.'+this.widgetName, function(e) { self._mouseClick(e, self); });
    },
    _mouseClick: function(e, self) {
      // do something with self.options
    }
  }
}());

This way you have access to self from within _mouseClick-
