new datatablesrequest(this.request)

本节，我将通过一个Demo，演示Datatables 和ASP.NET MVC的完美结合，可以这么说，如果这样的界面都能做出来，后台系统90%的界面功能都可以开发出来了。

用jquery Datatables 来开发确实是件比较蛋疼的事情（和Jquery EasyUI、MiniUI、ExtJs相比），用其它的第三方UI框架来实现相同的功能真是非常非常的简单，可是使用Datatables却是那么的吃力，至少我这么觉得，可能是因为我对这个控件使用得还不够纯熟。在官网，datatables默认使用的是bootstraps的样式，这里我已经把样式重写了一部分。

看见公司原有的系统，同样是使用ASP.NET MVC做的，在页面随便点击个东东，整个界面就刷新了，刷得我自己都受不了，更别指望固定表头啊什么什么的了，完全不存在用户体验啊！于是我就自己写了UI框架（也可以说是组装，但是我重写了许多东西）。

技术点：1、服务器端分页。2、查询（模糊查询）3、界面操作刷新后依旧保留当前分页 4、固定表头、表尾 5、动态控制列的隐藏和显示 6、全选、反选（数据行中复选框全部选中时，全选按钮自动选中，我发现很多程序员这个功能一直没做，可是说是bug么？） 7、服务器排序（功能我已经开发出来了，但是这里我没有写上去，这个网上我还没有看到实现的Demo） 8、特殊字段标红显示 9、滑动变色 10、单击行选中变色 ....

这里面 table.fnSetColumnVis(arr[i], tag);这行代码控制列动态隐藏和展示的时候，会重新加载数据，可以在后面加一个false参数，取消刷新。如： table.fnSetColumnVis(arr[i], tag,false);

请求参数封装类DataTablesRequest，这个类是从冠军的博客下载的，它主要用于解析datatables的请求参数，由于datatables支持多列排序，所以比较复杂。下载的这个类有点问题，那就是获取的排序方式一直是asc，于是我进行了修改，修改后的代码如下：

本篇我不想做过多的说明，我写了非常详实的注释，而且代码非常通俗易懂，界面的功能还是非常强大的，我相信，从这些犀利的代码中，你一定会获益良多。
