我正在使用ASP.NET-MVC 4开发应用程序。这里,我在布局页面中动态加载菜单。我创建了一个局部视图来动态加载菜单,并将其包含在布局页面中,如下所示:
MenuModel.cs:
public string Decode(BitArray bits)
{
Node current = this.Root;
string decoded = "";
foreach (bool bit in bits)
{
if (bit)
{
if (current.Right != null)
{
current = current.Right;
}
}
else
{
if (current.Left != null)
{
current = current.Left;
}
}
if (IsLeaf(current))
{
decoded += current.Symbol;
current = this.Root;
}
}
return decoded;
}
PartialController.cs:
public class MenuModel
{
public List<MainMenu> MainMenuModel { get; set; }
}
public class MainMenu
{
public int MainMenuID;
public string MainMenuName;
public string MainMenuController;
public string MainMenuAction;
}
LoadMenu.cshtml :(部分视图)
using Insights.Models;
[ChildActionOnly]
public ActionResult LoadMenu()
{
MenuModel ObjMenuModel = new MenuModel();
ObjMenuModel.MainMenuModel = new List<MainMenu>();
ObjMenuModel.MainMenuModel = GetMainMenu();
return PartialView(ObjMenuModel);
}
public List<MainMenu> GetMainMenu()
{
List<MainMenu> ObjMainMenu = new List<MainMenu>();
var context = new InsightsEntities();
ObjMainMenu = context.Insights_mMenu.Where(m => m.parentMenuUID == 0).Select(x => new MainMenu()
{
MainMenuID = x.menuUID,
MainMenuName = x.menuName,
MainMenuController = x.menuURLController,
MainMenuAction = x.menuURLAction
}).ToList();
return ObjMainMenu;
}
_Layout.cshtml:
@model Insights.Models.MenuModel
<link rel="stylesheet" href="~/MADMIN_files/style(2).css" />
<ul class="sidebar-menu on-click" id="main-menu">
<li class="active">
<div class="sidebar-menu-item-wrapper">
<a href="#">
<i class="icon-home"></i>
<span>Home</span>
</a>
</div>
</li>
@{
foreach (var MenuItem in Model.MainMenuModel)
{
<li class="active">
<div class="sidebar-menu-item-wrapper">
<a href='@Url.Action(@MenuItem.MainMenuAction, @MenuItem.MainMenuController)'><span>@MenuItem.MainMenuName</span></a>
</div>
</li>
}
}
</ul>
屏幕显示属于“报告”菜单的页面。在这里,我想通过将其css更改为“活动”来突出显示单击的菜单。有两个类“活动”和“非活动”。当我们动态加载菜单时如何实现这一目标?
答案 0 :(得分:0)
然后,您可以使用类似的内容来确定“子操作”中的“父级”操作和控制器名称。这可以与每个菜单项的值进行比较,以查看它是否确实是活动菜单项,如果是,则可以在菜单项上设置IsActive属性。然后只需使用IsActive属性来决定在渲染菜单时是否添加css类。
string actionName = this.ControllerContext.ParentActionViewContext.RouteData.Values["action"].ToString();
string controllerName = this.ControllerContext.ParentActionViewContext.RouteData.Values["controller"].ToString();
