在jquery中创建名称空间时出错

Question

I had write a code in js file

(function ($) {
    var $r = $.loadaccess;

    jQuery.loadaccess.page.user = {
        init: function () {
            debugger;
            var k = 'dd';
            alert(k);
        }
    };
})(jQuery);

var user = jQuery.loadaccess.page.user;

and I am calling it on .aspx page

$(document).ready(function () {

        jQuery.loadaccess.page.user.init();
    });

but it thrown error for me "Microsoft JScript runtime error: Unable to get value of the property 'page': object is null or undefined"

on this

jQuery.loadaccess.page.user = {
            init: function () {
                debugger;
                var k = 'dd';
                alert(k);
            }
        };

The error is pretty self descriptive, jQuery.loadaccess is null or undefined. What do you expect jQuery.loadaccess to be? You will need to create this 'namespace' yourself. For example:

jQuery.loadaccess = {
  page: {
    user: {
      init: function () {
          debugger;
          var k = 'dd';
          alert(k);
      }
    }
  }
};

I wouldn't suggest adding objects to the jQuery object though, rather create your own top level namespace.
