首页模块就是展示不同权限的最终结果了，在阅读这章之前若有些不明白，可看看后续的单独的权限模块，用户模块，目录模块后从整体上再看首页模块。
阅读该模块需要一定或者是比较熟练的js知识,EasyUI Tab控件知识。整个首页模块的流程是登陆模块获取到了用户的基本信息，可以访问的网页信息，目录信息后，封装在sessionManage会话中，通过JS文件做数据的格式转换及动作定义，通过Css文件做网页的效果美化。简而言之，就是获取后台数据渲染到网页。
首页模块的一级导航选择不同的信息关联二级导航，二级导航展开显示可以访问的页面链接。每一个链接在网页的展示模块通过EasyUI的Tab控件展示，可以实现如下效果:
对应单个的tab中显示的网页信息是通过iframe标签的方式实现的。及打开一个tab就创建一个iframe对象。关闭一个tab就释放该iframe对象。
首页模块的基本结构简图如下：
首页视图是由两部分视图组成的。主视图主要是展示整个的框架结构，还有一个部分视图主要是展示左侧的权限信息页面。主视图中比较关键的代码如下：
@using Models
@using Page = Models.Page
<!--先把页面model加载到视图-->
<!--解析Model生成一级导航目录信息-->
<ul class="menuchild">
@if (ViewBag.Navigation != null)
{
IList<Catalog> navigationList = (List<Catalog>)ViewBag.Navigation;
foreach (Catalog item in navigationList)
{
<li><a onclick="navigationClick(@item.CatalogId);">@item.CatalogName</a><i></i></li>
}
}
</ul>
<!--左边菜单容器 加载部分视图展示左边的菜单信息 -->
<div class="scroll-panel" id="scrollpanel">
<div style="top: -10.8px;" class="scroll-content" id="scrollcontent">
<div id="rightListDiv">
@Html.Partial("_rightMessage", new { navigationId = -1 })
</div>
</div>
</div>
首页详细视图代码如下：

首页加载共用了两个JS文件，其中视图IndexHome.cshtml对应default.js,_rightMessage.cshtml对应_rightMessage.js文件。
两个文件中关键的代码均是创建iframe对象和销毁iframe对象，部分代码如下：
/** 把iframe与Tab的属性结合起来。
* 增加iframe模式的标签页
* param {[type]} jq [description]
* param {[type]} params [description]
*/
addIframeTab: function (jq, params) {
return jq.each(function () {
if (params.tab.href) {
delete params.tab.href;
}
$(this).tabs(‘add‘, params.tab);
$(this).tabs(‘loadTabIframe‘, { ‘which‘: params.tab.title, ‘iframe‘: params.iframe });
});
},
/**
* 更新tab的iframe内容
* param {jq Object} jq [description]
* param {Object} params [description]
* return {jq Object} [description]
*/
updateIframeTab: function (jq, params) {
return jq.each(function () {
params.iframe = params.iframe || {};
if (!params.iframe.src) {
var $tab = $(this).tabs(‘getTab‘, params.which);
if ($tab == null) return;
var $tabBody = $tab.panel(‘body‘);
var $iframe = $tabBody.find(‘iframe‘);
if ($iframe.length === 0) return;
$.extend(params.iframe, { ‘src‘: $iframe.attr(‘src‘) });
}
$(this).tabs(‘loadTabIframe‘, params);
});
}
//创建Frame
function createFrame(url) {
var s = ‘<iframe scrolling="hidden" frameborder="0" src="‘ + url + ‘" style="width:100%;height:98%;"></iframe>‘;
return s;
};
//添加tab页
function addTab(title, tabHref) {
if ($("#pageTab").tabs("exists", title)) {
$("#pageTab").tabs("select", title);
} else {
$(‘#pageTab‘).tabs(‘addIframeTab‘, {
tab: { title: title, closable: true },
iframe: { src: tabHref }
});
}
default.js文件的完整代码如下：

首页控制器就是把SessionManage会话类中的信息取出来。部分代码如下：
//一级导航目录
IList<Catalog> navigationList = SessionManage.CurrentUser.NavigationList;
//操作权限页面
IList<Catalog> rightList = SessionManage.CurrentUser.RightList;
if (navigationList != null && navigationList.Count > 0)
{
IList<Catalog> currentRight =
(from item in rightList where item.ParentId == navigationList.First().CatalogId select item)
.ToList();
ViewBag.Navigation = navigationList;
ViewBag.RightList = currentRight;
}
public PartialViewResult RightMessage(int navigationId)
{
//根据一级导航信息，展示二级导航信息
}
IndexHomeController.cs控制器的详细代码如下：
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 using System.Web.Mvc; 6 using Session; 7 using OdbcDbAccess; 8 using System.Data; 9 using Models; 10 11 12 namespace CqReportSystem.Controllers 13 { 14 public class IndexHomeController : Controller 15 { 16 /// <summary> 17 /// **************************** 18 /// 功能：主页 19 /// 作者：王令 20 /// 时间：2015-7-18 21 /// 邮箱：1129137758@qq.com 22 /// **************************** 23 24 public ActionResult IndexHome() 25 { 26 if (SessionManage.CurrentUser == null) 27 { 28 Response.Redirect("/"); 29 } 30 else 31 { 32 //一级导航目录 33 IList<Catalog> navigationList = SessionManage.CurrentUser.NavigationList; 34 //操作权限页面 35 IList<Catalog> rightList = SessionManage.CurrentUser.RightList; 36 if (navigationList != null && navigationList.Count > 0) 37 { 38 IList<Catalog> currentRight = 39 (from item in rightList where item.ParentId == navigationList.First().CatalogId select item) 40 .ToList(); 41 ViewBag.Navigation = navigationList; 42 ViewBag.RightList = currentRight; 43 } 44 45 ViewData["UserName"] = SessionManage.CurrentUser.OperatorName; 46 } 47 return View(); 48 } 49 50 51 /// <summary> 52 /// 根据一级目录展示二级目录及访问页面 53 /// </summary> 54 /// <param name="navigationId"></param> 55 /// <returns></returns> 56 public PartialViewResult RightMessage(int navigationId) 57 { 58 if (SessionManage.CurrentUser == null) 59 { 60 Response.Write("<script> window.parent.location.href = ‘/Login/Login‘;</script>"); 61 } 62 else 63 { 64 IList<Catalog> rightList = SessionManage.CurrentUser.RightList; 65 if (navigationId == -1) 66 { 67 IList<Catalog> navigationList = SessionManage.CurrentUser.NavigationList; 68 navigationId = navigationList.First().CatalogId; 69 } 70 71 IList<Catalog> currentRight = 72 (from item in rightList where item.ParentId == navigationId select item) 73 .ToList(); 74 ViewBag.RightList = currentRight; 75 } 76 77 return PartialView("_rightMessage"); 78 } 79 80 81 public ActionResult Home() 82 { 83 return View(); 84 } 85 86 } 87 }
