; (function ($, window, document, undefined) {
    "use strict";

    var defaults = {
        name: "xiaoxiao",
        age: 18
    };

    function ShowPepleInfo($ele,options,callback) {
        this.$ele = $ele;
        this.options = options = $.extend(defaults, options || {});
        this.callback = callback || {};//若为undefined则新建callback对象
        this.init();
    }

    ShowPepleInfo.prototype = {
        constructor: ShowPepleInfo,

        init: function () {
            this.renderHtml();
            this.bindEvent();
        },

        renderHtml: function () {
            var options = this.options;
            var html = [];
            html.push('<div class="info">');
            html.push('<p>姓名：' + options.name + '</p>');
            html.push('<p>年龄：' + options.age + '</p>');
            html.push('</div>');

            this.$ele.html(html.join(""));
        },

        bindEvent: function () {
            var that = this;
            that.$ele.delegate("p", "click", function () {//直接把事件绑定在父元素$ele
                alert($(this).html());

                if (typeof that.callback == 'function') {
                    that.callback($(this).html());//执行回调函数
                }
            });

        },

        //others...
    }

    $.fn.showPeopleInfo = function(options,callback){
        options = $.extend(defaults, options || {});
        return new ShowPepleInfo($(this), options, callback);
    }

})(jQuery)

//使用
$("#main").showPeopleInfo({ name: "dada", age: 20 }, function (e) { alert(e); });
//不用立即执行函数包括
var show = new ShowPepleInfo($("#main"), { name: "dada", age: 20 }, function (e) { alert(e); });
alert(show.options.name);
