Extending a jQuery prototype -

i have method addobject on jquery prototype have done using jquery.fn.extend().

jquery.fn.extend({     addobject : function(objectkey){         this[objectkey] = {};     } }); 

now want add method addnewobject prototype. trying emulate below scenario

function addobject(){     ... }  addobject.prototype.addnewobject = function(){     ... } 

how addobject accessible new keyword?

instead of using extend use:

// insulate plugin in iife (function() {     // declare function     function addobject(options) {         return this.each(function(){});     }     // add prototypes     addobject.prototype.addnewobject = function() {}      // extend plugin passing function reference     $.fn.addobject = addobject;   })(jquery);
