由于第一次写jq插件，中间有借鉴别人的代码。

    $.fn.creatPage = function(option) {

        var option = $.extend(initOption, option);
        
        ms.init(this, option);
    }
})()

HTML

<div class="mod-page-cont" id="pageCont">
                       
</div>

用法

$("#pageCont").creatPage({
        pageCount: 18,            //总页数
        currentPage: 1,            //当前选中页
        backFunction: function(){    //回调函数
            
        }
    });
