我们要搭建的框架是企业级开发框架，适用用企业管理信息系统的开发，如：oa、hr等
1、框架名称：sampleframe。
2、搭建原则：最少知识原则。
3、先定义一个简单的编码规范：除类名和接口名外，其余首字母小写。
4、准备开发环境：vs2010及以上（mvc4）、sqlserver、jquery2.0和easyui1.4.5
首先来看一下列表页面的效果图：
我们期望简洁带前台代码，如下：
<table id="datagrid" class="easyui-datagrid" url="getlist" toolbar="#toolbar">
<thead>
<tr>
<th field="customerid" sortable="true" data-options="sortable:true" width="50">
customerid
</th>
<th field="companyname" data-options="sortable:true" width="50">
companyname
</th>
<th field="phone" width="50">
phone
</th>
<th field="address" width="50">
address
</th>
</tr>
</thead>
</table>
<div id="toolbar">
<div>
<a class="easyui-linkbutton" iconcls="icon-add" onclick="add();">添加</a>
<a class="easyui-linkbutton" iconcls="icon-edit" onclick="edit();">修改</a>
<a class="easyui-linkbutton" iconcls="icon-remove" onclick="del();">删除</a>
</div>
<div>
<input id="querybox" class="easyui-textbox" buttonicon="icon-search" style="width: 200px;"
data-options="onclickbutton:function(){loadlist(loadlistsettings);}" />
<a class="easyui-linkbutton" iconcls="icon-find" onclick="showquerywindow();">
详细查询</a>
</div>
</div>
<script type="text/javascript">
var loadlistsettings = { searchfields: "customerid,companyname", prompt: "请输入客户id或公司名称" };
</script>
<script type="text/javascript">
pageinit();
</script>
为了这样简洁的前台，我们需要准备：
1、通用的布局模板_layout.cshtml。base.css、base.js、defaultsettings.js、tool.js和private.js见后面
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<meta http-equiv="x-ua-compatible" content="ie=edge,chrome=1" />
<link href='/webresource/easyui/themes/default/easyui.css' rel='stylesheet' type='text/css' />
<link href='/webresource/easyui/themes/icon.css' rel='stylesheet' type='text/css' />
<link href='/webresource/base.css' rel='stylesheet' type='text/css' />
<script src="/webresource/jquery/jquery.min.js" type="text/javascript"></script>
<script src="/webresource/jquery/json2.js" type="text/javascript"></script>
<script src="/webresource/easyui/jquery.easyui.min.js" type="text/javascript"></script>
<script src="/webresource/easyui/locale/easyui-lang-zh_cn.js" type="text/javascript"></script>
<script src="/webresource/tool.js" type="text/javascript"></script>
<script src="/webresource/base.js" type="text/javascript"></script>
<script src="/webresource/defaultsettings.js" type="text/javascript"></script>
<script src="/webresource/private.js" type="text/javascript"></script>
@rendersection("scripts", required: false)
</head>
<body style="width: 100%; height: 100%; margin: 0px;">
@renderbody()
</body>
</html>
2、平台样式表base.css
.icon-find
{
background: url('icons/find.png') no-repeat center center;
}
.datagrid-toolbar div:nth-child(1)
{
float: left;
width: 60%;
}
.datagrid-toolbar div:nth-child(2)
{
margin-left: 60%;
margin-right: 10px;
width: auto;
text-align: right;
}
3、基本方法脚本base.js
//取消自动渲染
$.parser.auto = false;
function pageinit() {
//改变控件默认值
$.fn.linkbutton.defaults.plain = true;
$.fn.datagrid.defaults.fit = true;
$.fn.datagrid.defaults.fitcolumns = true;
$.fn.datagrid.defaults.pagination = true;
//显示ajax异常信息
$(document).ajaxerror(function (event, xhr, options, exc) {
$.messager.alert({ title: '异步请求出错', msg: xhr.responsetext, icon: "error" });
});
//地址栏传参允许中文
jquery(document).ajaxsend(function (event, request, options) {
options.url = encodeuri(options.url);
});
$.parser.parse();
}
function loadlist(settings) {
var settings = $.extend(true, {}, loadlistdefaultsettings, settings);
if ($("#" + settings.gridid).length == 0)
$.messager.alert({ title: "系统异常", msg: "datagrid：" + settings.gridid + "不存在！", icon: "error" });
var quickquerydata = [];
if ($("#" + settings.queryboxid).length > 0) {
var val = $("#" + settings.queryboxid).textbox("getvalue");
if (settings.searchfields && val) {
var keys = settings.searchfields.split(',');
for (i = 0, len = keys.length; i < len; i++) {
quickquerydata.push({ field: keys[i], method: 'inlike', value: val });
}
}
}
var querydata = []; //详细查询预留
//加载数据
$("#" + settings.gridid).datagrid("load", { quickquerydata: json.stringify(quickquerydata), querydata: json.stringify(querydata) });
}
4、基本脚本默认值defaultsettings.js
//查询参数设置
var loadlistdefaultsettings = {
url: "getlist",
gridid: "datagrid",
querywindowid: "querywindow",
queryboxid: "querybox",
searchfields: "name",
addquerystring: true,
prompt: "请输入"
};
5、可能需要使用的工具方法tool.js
//判断是否包含地址栏参数
function hasquerystring(key, url) {
if (typeof (url) == "undefined")
url = window.location.search;
var re = new regexp("[?&]" + key + "=([^\\&]*)", "i");
var a = re.exec(url);
if (a == null) return false;
return true;
}
//获取地址栏参数,如果参数不存在则返回空字符串
function getquerystring(key, url) {
if (typeof (url) == "undefined")
url = window.location.search;
var re = new regexp("[?&]" + key + "=([^\\&]*)", "i");
var a = re.exec(url);
if (a == null) return "";
return a[1];
}
//将当前地址栏参数加入到url
function addurlsearch(url) {
var newparams = [];
var paramkeys = window.location.search.replace('?', '').split('&');
for (var i = 0; i < paramkeys.length; i++) {
var key = paramkeys[i].split('=')[0];
if (key == "" || key == "_t" || key == "_winid" || key == "istab")
continue;
if (!hasquerystring(key, url))
newparams.push(paramkeys[i]);
}
if (url.indexof('?') >= 0)
return url + "&" + newparams.join('&');
else
return url + "?" + newparams.join('&');
}
//url增加参数
function addsearch(url, key, value) {
if (!hasquerystring(key, url)) {
if (url.indexof('?') >= 0)
return url + "&" + key + "=" + value;
else
return url + "?" + key + "=" + value;
}
else
return url;
}
//获取数组中对象的某个值，逗号分隔
function getvalues(rows, attr) {
var fieldvalues = [];
for (var i = 0; i < rows.length; i++) {
if (rows[i] != null)
fieldvalues.push(rows[i][attr]);
}
return fieldvalues.join(',');
}
6、可能需要使用的私有方法private.js，此文件包含的方法专供base.js使用，开发web时禁止使用
//替换掉url中的{}参数
function replaceurl(settings, pty) {
if (!pty)
pty = "url";
if (!settings[pty])
return;
var str = settings[pty];
var guid = "";
var result = str.replace(/\{[0-9a-za-z_]*\}/g, function (e) {
var key = e.substring(1, e.length - 1);
if (key == "guid") {
if (!guid) {
$.ajax({
url: "getguid",
type: "post",
async: false,
success: function (text, textstatus) {
guid = text;
}
});
}
return guid;
}
if (hasquerystring(key)) //从地址栏返回
return getquerystring(key);
if (settings.currentrow && settings.currentrow[key])//从当前行返回
return settings.currentrow[key];
if (settings.paramfrom) { //从指定控件返回
var ctrl = mini.get(settings.paramfrom);
if (ctrl == undefined) {
$.messager.alert({ title: 'ui出错', msg: "id为" + settings.paramfrom + "的控件不存在！", icon: "error" });
return;
}
else if (ctrl.showcheckbox) {
return getvalues(ctrl.getcheckednodes(), key);
}
else if (ctrl.getselecteds)
return getvalues(ctrl.getselecteds(), key);
else if (ctrl.getvalue)
return ctrl.getvalue();
}
return e;
});
settings[pty] = result;
return result;
}
//转化为全路径
function changetofullurl(settings) {
var url = settings.url;
if (url.indexof('/') == 0 || url.indexof("http://") == 0 || url.indexof('?') == 0 || url == "")
return url;
currenturlpathname = window.location.pathname;
var currentpathnameparts = currenturlpathname.split('/');
var pathnameparts = url.split('?')[0].split('/');
if (currentpathnameparts[currentpathnameparts.length - 1] == "")
currentpathnameparts.pop(); //去掉一个反斜线
if (pathnameparts[pathnameparts.length - 1] == "")
pathnameparts.pop(); //去掉一个反斜线
var index = currentpathnameparts.length - 1;
for (var i = 0; i < pathnameparts.length; i++) {
if (pathnameparts[i] == "..") {
index = index - 1;
if (index <= 0) {
$.messager.alert({ title: "系统异常", msg: "url错误：" + url + "！", icon: "error" });
return;
}
continue;
}
if (index < currentpathnameparts.length)
currentpathnameparts[index] = pathnameparts[i];
else
currentpathnameparts.push(pathnameparts[i]);
index = index + 1;
}
var length = currentpathnameparts.length;
for (var i = index; i < length; i++) {
currentpathnameparts.pop();
}
var result = currentpathnameparts.join('/');
if (url.indexof('?') > 0)
result += url.substring(url.indexof('?'));
settings.url = result;
}
我们期望简洁的后台代码，如下：

{
sqlhelper sqlhelper = new sqlhelper("demo");
var data = sqlhelper.executegriddata("select *,id=customerid from customer", qb);
return json(data);
}
}

}
response.write(jsonhelper.tojson(dic));
}
else

6、json序列化和反序列的帮助类jsonhelper：
using system;

using system.linq;
using system.text;
using newtonsoft.json.converters;

if (string.isnullorempty(json)) return new list<dictionary<string, object>>();
return toobject<list<dictionary<string, object>>>(json);
}
/// <summary>
/// 组装对象
/// </summary>
/// <param name="json"></param>
/// <param name="obj"></param>
public static void populateobject(string json, object obj)
{
if (string.isnullorempty(json)) return;
jsonconvert.populateobject(json, obj);
}
}
}
7、用于区分系统异常和业务异常的businessexception：
using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.runtime.serialization;
namespace formula
{
/// <summary>
/// 业务异常
/// </summary>
[serializable]
public class buessinessexception : exception
{
/// <summary>
/// 系统异常构造函数
/// </summary>
public buessinessexception()
{
}
/// <summary>
/// 系统异常构造函数
/// </summary>
/// <param name="message">异常的消息</param>
public buessinessexception(string message)
: base(message)
{
}
/// <summary>
/// 系统异常构造函数
/// </summary>
/// <param name="message">异常的消息</param>
/// <param name="inner">内部的异常</param>
public buessinessexception(string message, system.exception inner)
: base(message, inner)
{
}
/// <summary>
/// 系统异常构造函数
/// </summary>
/// <param name="info">存有有关所引发异常的序列化的对象数据</param>
/// <param name="context">包含有关源或目标的上下文信息</param>
public buessinessexception(serializationinfo info, streamingcontext context)
: base(info, context)
{
}
}
}
