Question

I’m writing a plugin, and I got the basic setup from the jQuery plugin authoring tutorial:

(function( $ ){

  var methods = {
    init : function( items ) { 
        /* do stuff */
    },
    reset : function( name ) {
        // here I need the var items from init
    }
  };

  $.fn.myplugin = function( method ) {

    // Method calling logic
    if ( methods[method] ) {
      return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 ));
    } else if ( typeof method === 'object' || ! method ) {
      return methods.init.apply( this, arguments );
    } else {
      $.error( 'Method ' +  method + ' does not exist on jQuery.tooltip' );
    }    

  };

})( jQuery );

How can I get in the method reset the variable items from init?

Thanks and regards, alex

You could store them in the smallest common scope, e.g. the methods object:

  var methods = {
    init : function( items ) { 
        /* do stuff */
        methods.myData = 15;
    },
    reset : function( name ) {
        // here I need the var items from init
        alert(methods.myData * 2); // alerts 30
    }
  };
