1)我在db上有2个选项卡类别和子类别,关系为1到多(使用实体框架)
2)我必须创建一个像这样的垂直菜单
<ul>
<li>category 1
<ul>
<li>subcategory 1</li>
<li>subcategory 2</li>
<li>subcategory 3</li>
</ul>
</li>
</ul>
我认为我的问题在于我的功能
Function List_category_subcategory() As List(Of WHAT HERE???????)
Using db As New DBTestEntities
Dim q = From cat In db.categories Join subcat In db.subcategories On cat.CategoryID Equals subcat.CategoryID _
Select New With {cat.CategoryName, subcat.SubCategoryName}
List_category_subcategory = WHAT HERE???????
End Using
End Function
因为我不知道必须返回什么函数(可能是列表集合)
在我看来之后必须循环一切
类似的东西
<ul>
<% For Each cat In ??????%>
<li><a href="#"><%=Html.Encode(cat.CategoryName)%></a>
<ul>
<% For Each subcat In ???????%>
<li><%=Html.Encode(subcat.SubCategoryName)%></li>
<% Next%>
</ul>
</li>
<% Next%>
</ul>
答案 0 :(得分:1)
SubCategory
不应该是category
的属性(这似乎更自然,但我可能在这里错了)?此外,嵌套循环中存在格式错误的li
标记(<li<%=
):
<ul id="menu-1" class="menu">
<% For Each category In Model.Category %>
<li>
<a href="#"><%= Html.Encode(category.CategoryName) %></a>
<ul>
<% For Each subcategory In category.SubCategory %>
<li>
<%= Html.Encode(subcategory.SubCategoryName) %>
</li>
<% Next %>
</ul>
</li>
<% Next %>
</ul>
答案 1 :(得分:0)
缺少关闭&gt;在内心?
