　　个人感觉，写插件，插件的具体结构，能用原生结构，还是用原生结构的好，最后桥接在jquery上.

　　如果像下面这样，看起来是不是有点 蛋疼呢。

(function ($) {
    $.love.defaults = {
        // ......
    };
    $.love = function (element, o) {
        this.element = element;
        this.options = $.extend({}, $.love.defaults, o);
        // ......
    };

    var $love = $.love;
    $love.fn = $love.prototype = {
        verson: '0.0.1'
        // ......
    };
    $love.fn.extend = $love.extend = $.extend;

    $love.fn.extend({
        metod: function () {

        }
        // ......
    });

    $.fn.ilove = function (o) {
        // ......
    };
})(jQuery);
