asp.net-mvc - @Html.Hidden 无法正确生成 id 和 value

Question

我需要创建一个隐藏变量，其结果为Url.Action. 以下代码不会产生所需的结果。需要纠正什么以产生所需的结果？

当前输出

<input name="/Controller/Action" type="hidden" value="{ Id = hiddenUrl }" />

所需输出

<input id="hiddenUrlName" type="hidden" value="/Controller/Action" />

代码

 <div class="loader">
    @Html.Hidden(@Url.Action("Action", "Controller"),new { Id = "hiddenUrl"})
 </div>

Answer 1

You've got your overloads mixed up. You want this one http://msdn.microsoft.com/en-us/library/dd492181(v=vs.108).aspx

@Html.Hidden("hiddenUrlName", Url.Action("Action", "Controller"),
                                                         new { Id = "hiddenUrl"})

You also don't need the @ in the Url.Action

Or which is directly equivalent but not using the HTML helpers.

<input id="hiddenUrl" name="hiddenUrlName" type="hidden" 
                             value="@Url.Action("Action", "Controller")" />

Answer 2

也许试试这个：

@Html.Hidden("hiddenUrlName", Url.Action("Action", "Controller"))

输出应该是这样的：

<input id="hiddenUrlName" name="hiddenUrlName" type="hidden" value="/Controller/Action" />
