起风网我们在项目开发中，做得最多的可能就是CRUD，那么我们如何在ASP.NET MVC中来做CRUD呢？如果说只是单纯实现功能，那自然是再简单不过了，可是我们要考虑如何来做得比较好维护比较好扩展，如何做得比较漂亮。做开发要有工匠精神，不要只求完成开发任务，那样的话，永远停留在只是简单的写业务逻辑代码水平，我们要做有追求的程序员。本来这么简单的东西，我真是懒得写，但是看到即便是一些工作了好些年的人，做东西也是只管实现功能，啥都不管，还有些界面css样式要么就硬编要么就毫无规则的在页面中进行穿插，遇到要设置间距甚至直接写多个 ，我觉得还是要写出来给那些人看下。硬编的前提是只有你这一个界面使用。
我们先来看下我们要实现的效果，功能需要：新增、修改、删除、查询、分页、排序、导出excel、打印、上传图片、支持表单验证，优雅的实现有多简单？非常简单。
需要用到哪些UI组件？我都是基于bootstrap这种扁平化响应式风格的，jquery.dataTables.js、toastr.js、bootstrapValidator.js、bootstrap-confirmation.js、printThis.js
由于是演示用，所以控制器中直接调用了EF上下文操作，重点是看前端部分的渲染和交互，不要重复你的代码！不要重复你的代码！不要重复你的代码！重要的事情说三遍！为什么没有用mvc自带的模型验证？答：太傻逼！1、样式改起来操蛋；2、每次要点击提交表单才促发验证。
这里表数据量少，是直接一次性加载，然后内存中分页的，如果表数据量多，那么就要用服务器分页，同样很简单。修改下配置项，如下所示：然后控制器中对应的方法稍微修改下即可。
options.bServerSide = true;，
options.fnServerParams = function (aoData) { //查询条件 aoData.push( { "name": "LogName", "value": $("#LogName").val() } ); };

我们进行二次封装的UI组件对象，他们的options属性，是复杂属性，也就是类似与引用类型，要使用深拷贝然后再去修改，否则修改的是引用而不是副本。我这里没有去使用clone，而是直接在options对象上进行赋值了，那是因为我赋值的那些属性每个引用页面都会去再赋值一遍，而js是运行在客户端的，也就是说每个客户的电脑上面都会有一份完整的js文件副本，这和运行在服务器端的C#语言是不一样的。其实使用 var options = clone(DataTablesObj.options);再去给options赋值是标准做法，但是会失去一部分性能。我的js水平太菜，所以封装得不是特别好，但是至少页面干净、方便维护。
js方法上面的注释，我也是按照自定义的风格进行注释，参数用()括起来，可选参数就用[]，这些东西都可以当成约定或者规范，目的就是为了让所有的开发人员写的代码像一个人写的。本来我想把方法的参数都封装成一个对象的，只是之前觉得参数个数少，就没有那样去封装了，参数用对象的好处就是可以无序，而且更易扩展，所有这些进行二次封装的UI组件，文件命名我都加了前缀base-，其实里面的对象命名我是加的后缀Obj，你也可以根据自己的爱好设定，比如说公司名称简写作为前缀，但是一定确定了，就要团队成员遵守约定。
日期组件同样进行封装base-Datetimepicker.js，这里的打印我暂时就没有去进行封装了。在js中通常使用原型链的方式来实现继承，我这里没有使用，原因2点，一是自身对这块掌握得不好，二是公司都是后端开发人员，就按照这种最简单的方式进行封装。

那么其实我们界面上真正自己要写的就3个View，3个js，一个控制器提供对应的方法调用，其它的不管是C#还是js都去进行封装，css样式通通按照规范写成皮肤文件。项目中可以有一个皮肤css，一个布局css，一个自定义css。
所以说.net做东西就是这么简单，看似复杂的功能界面，一下子就搞定了，只要把东西都封装好了，做一个这样的功能最多大半天就搞定，仔细看下js总共就写几十行左右，还算上了复制粘贴修改下的，哪里需要去经常加班？加班应该是php程序员和java程序员的专利，做不加班的.net程序员~
