ASP net 在项目中使用面包屑导航方法

MVC 在项目中使用面包屑导航
给框架添加一个面包屑导航
1.创建一个类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SAS.Model.AdminCommon
{
public class BreadCrumbsModel
{
public BreadCrumbsModel()
{
BreadCrumbList = new List<BreadCrumbModel>();
public bool IsOnlyIndex { get; set; }
public string CurrentName { get; set; }
public List<BreadCrumbModel> BreadCrumbList { get; set; } }
public class BreadCrumbModel
{
public bool IsIndex { get; set; }
public bool IsParent { get; set; }
public string Name { get; set; }
public string Icon { get; set; }
public string Url { get; set; }
public string Id { get; set; }
}
}
2.创建一个部分视图
public PartialViewResult BreadCrumbs(string id)
{
List<BPMS_SysMenu> list = new List<BPMS_SysMenu>(); StringBuilder strWhere = new StringBuilder();
BPMS_SysMenu parentModule = new Model.BPMS_SysMenu();
BPMS_SysMenu childModule = new Model.BPMS_SysMenu();
list = bll.GetModelList(strWhere.ToString());
var model = new BreadCrumbsModel();
parentModule = bll.GetModel(id);
var module = bll.GetModelList(strWhere.ToString()).FirstOrDefault(d => d.MenuId == parentModule.ParentId);
if (module != null)
{
var parentModel = new BreadCrumbModel
{
IsParent = true,
Name = module.FullName,
//Url = module.NavigateUrl,
Icon = module.Img
};
model.BreadCrumbList.Add(parentModel);
var currentModel = new BreadCrumbModel
{
IsParent = false,
Name = parentModule.FullName,
Url = parentModule.NavigateUrl,
Id = parentModule.MenuId,
Icon = ""
};
model.CurrentName = ; model.BreadCrumbList.Add(currentModel); ViewBag.CurrentTitle = parentModule.FullName; }
return PartialView(model);
}
3.给页面添加导航的视图代码
@using SAS.Model.AdminCommon
@model BreadCrumbsModel
<div class="page-bar">
<ul class="page-breadcrumb">
@foreach (var item in Model.BreadCrumbList) {
if (item.IsIndex)
{
<li>
<i class="@item.Icon"></i>
<a href="@Url.Action("index", "main", new { Area = "admin" })" title="@">@</a>
<i class="fa fa-angle-right"></i>
</li>
}
else
{
if (Model.BreadCrumbList.Count > 1)
{
if (item.IsParent)
{
<li>
<i class="@item.Icon"></i>
<a href="javascript:void(0)" title="@">@</a>
<i class="fa fa-angle-right"></i>
</li>
}
else
{
<li>
<a href="@item.Url?id=@item.Id">@</a>
</li>
}
}
}
}
</ul>
</div>
<h3 class="page-title">@Model.CurrentName</h3>
4.最后在要显示的地方，加上一段代码，即可运行
@{ Html.RenderAction("BreadCrumbs", "Main", new { id = @ViewBag.CLASSID });}。
