剃刀中的有效選擇選項

Question

我正在使用我的網站的移動版本。我有選擇操作的選項，但是當我選擇時，例如「關於」它會帶我到正確的頁面，但導航欄返回到「主頁」選項。我如何去做這件事？在此先感謝

<select class="navbar-nav" style="width:250px" onchange='location.href = this.value'> 
       <option value="@Url.Action("Index", "Home")">Home</option> 
       <option value="@Url.Action("About", "Home")">About</option> 
       <option value="@Url.Action("Products", "Home")">Products</option> 
       <option value="@Url.Action("Services", "Home")">Services</option> 
       <option value="@Url.Action("Contact", "Home")">Contact</option> 
      </select> 

Answer 1

<option selected="@ViewBag.Home" value="@Url.Action("Index", "Home")">Home</option> 
    <option selected="@ViewBag.About" value="@Url.Action("About", "Home")">About</option> 
    <option selected="@ViewBag.Products" value="@Url.Action("Products", "Home")">Products</option> 
    <option selected="@ViewBag.Services" value="@Url.Action("Services", "Home")">Services</option> 
    <option selected="@ViewBag.Contact" value="@Url.Action("Contact", "Home")">Contact</option> 

，並在您Home.cshtml

@{ 
    ViewBag.Home = true; 
} 

和其他頁面。

Answer 2

你可以這樣說：

@{ 
    Dictionary<string, string> menu = new Dictionary<string, string>(); 
    menu.Add("Home", @Url.Action("Index", "Home")); 
    menu.Add("About", @Url.Action("About", "Home")); 
    menu.Add("Products", @Url.Action("Products", "Home")); 
    menu.Add("Services", @Url.Action("Services", "Home")); 
    menu.Add("Contact", @Url.Action("Contact", "Home"));  

} 
<select class="navbar-nav" style="width:250px" onchange='location.href = this.value'> 
    @foreach (var m in menu) 
    { 
    <option value="@m.Value" @(m.Value == Request.Url.AbsoluteUri ? "selected='selected' " : "")>@m.Key</option> 
    } 
</select>
