的分页不过他的不是ajax 也像博客园的首页分页(转载请保持原著)：
思路：1：创建页码 如图:
服务器需要的返回总数(具体创建dom自己发挥 以及有多少页 具体思路 假如每页显示10条 总数除以10 1：结果等于总数不需要操作 2： 如果大于或者等于1默认为1 3：利用正则
判断有小数点后加+1)代码如下：pageNumberCount 是总数
pageNumberCount = json.total / 10, _RegExp = /\./;
if (pageNumberCount <= 1) {
pageNumberCount = 1;
} else if (_RegExp.test(pageNumberCount)) {
pageNumberCount = parseInt(pageNumberCount);
pageNumberCount = pageNumberCount + 1;
}:
2：点击1获取第一页数据 点击2获取第2页数据。。。。后面就是这样的规律 看完后是不是觉得很容易啊！没错ajax就是那么简单(呵呵 不过也是用的别人写好的jquery内库)
最后附加代码：
/*
*datatabel tootip提示
*/
function getHtml(){
this.html = "";
}
getHtml.prototype = {
show: function(){
var toolTip = $("<div id='tooltip' width='100px' height='12px'>" + this.html + "</div>");
return toolTip;
}
}
/*
*jquery datatable
*/
function _getDataTable(){
}
/*
* jquery datatable 扩展
* show 显示表格
* getupPage 点击上一页向左递减
* getdowmPage 点击下一页向右自加
* getPageIndex 点击页码操作
* createPageNumber 创建页面dom 操作
* btnCreatePageNumber 点击确定按钮查询操作
* createDateMenu 创建表头Menu
*/
