javascript - How do I access a jQuery plugin variable from within method? -

i'm trying write simple jquery plugin, i've come stumbling block though in i'm not sure how access variables on plugin within method plugin.

(function($) {     $.fn.testplugin = function() {         var testvar = "hello world";         alert(testvar);         $.fn.testplugin.testmethod();     };      $.fn.testplugin.testmethod = function() {         alert($.fn.testplugin.testvar);     }; }(jquery));  $("body").testplugin(); 

fiddle here

this code first alerts "hello world" "undefined" (so attempting access within method returns empty variable), there way access testvar within testmethod? not possible? going in wrong way?

you creating local variable inside first method. makes it's scope restricted method itself.

instead, should create variable reference plugin :

$.fn.testplugin.testvar = "hello world";
