Boilerplate jQuery Plugin - replace "Constructor" with constructor function name and replace "pluginName" with name of plugin

jqueryplugin.js

(function($, document, window, undefined) {
'use strict';

var Constructor = function( elm, options, id ) {
  this.el = elm;
  this.$el = $(elm);
  this.init( options );
};

Constructor.prototype = {

  init: function( options) {
        this.options = $.extend( true, {}, $.fn.pluginName.defaults, options );
  },

  destroy : function ( ) {}

};

jQuery.fn.pluginName = function( options ) {

  switch ( typeof options ) {
    case 'number': //if the plugin acccepts a number. if not remove
      Constructor = $(this).data( 'Constructor' );
      if ( Constructor !== null ) {
       //do something
      }
      break;
    case 'string':  // if the plugin accepts a string value (typically function name)
      Constructor = $(this).data( 'Constructor' );
      if ( Constructor !== null ) {
        switch( options ) {
          case 'init':
            Constructor.init();
            break;
          case 'destroy':
            Constructor.destroy();
            break;
        }
      }
      break;
    default:  // standard object
      return this.each( function () {
        new Constructor( $( this ), options );
      });
  }
};


jQuery.fn.pluginName.defaults = {
  option1 : '',
  option2 :0,
  //etc
};

}(jQuery, document, window));
