基于AJAX的分页类实现代码

nbsp;this.childrenCount = $(''#tbody_id''+this.id).children().size();
        }
        //开始查询
        this.url = url;
        if(params == null) params = {};
        $.extend(params,{pageNo:this.pageNo,pageSize:this.pageSize});
        this.params = params;
        var thisObj = this;
        var options = {
            url : url,
            data : params,
            async : false, //采用同步方式请求
            type : ''POST'',
            dataType : ''json'',
            error : function(xmlhttp, errInfo, e) { //请求出错处理:如:404等
                if (xmlhttp.status == 200) alert(''您已经很长时间没有访问网站,请退出后重新登陆！'');
                else alert(''请求后台服务时发生错误：'' + xmlhttp.status);
            },
            success : function(data){
                //删除上一次的数据
                $(''#tbody_id''+thisObj.id).children().filter('':gt(''+(thisObj.childrenCount-1)+'')'').remove();
                thisObj.pageList(data.data);
                thisObj.pageBar(data.total);
                if($.isFunction(thisObj.afterQuery)) thisObj.afterQuery();
            }
        };
        if($.isFunction(this.beforeQuery)) this.beforeQuery();
        $.ajax(options); //发送请求
    }

    this.pageList = function(data){
        var filedArr = this.templat.match(/\{[A-Za-z0-9_]+\}/ig);
