一个for循环中设置了HiddenFor硬codeD值 [英] Set a hardcoded value in a HiddenFor within a for-loop

问题描述

当只有一个人选择我还需要分配硬codeD值TRUE到人民[我] .IsSelected属性，以满足我的验证。

我怎么能这样做？

  @if（hasMoreThanOnePerson）
{
    ＆所述; TD＆GT;
        @ Html.CheckBoxFor（M = GT; m.People [I] .IsSelected）
    ＆LT; / TD＆GT;
}
其他
{
    @ Html.HiddenFor（M = GT; m.People [I] .IsSelected，真）//设置为TRUE总是隐藏字段内与索引循环
}
 

解决方案

使用 htmlAttributes 设置值财产隐藏字段使用此重载或< A HREF =htt​​ps://msdn.microsoft.com/en-us/library/ee703622%28v=vs.118%29.aspx相对=nofollow>此重载：

  @ Html.HiddenFor（M = GT; m.People [I] .IsSelected，新{值=真}）
 

它将输出HTML这样的：

 ＆LT;输入ID =YourModel.People [0] .IsSelected
       NAME =YourModel.People [0] .IsSelected
       类型=隐藏
       值=真＆GT;
 

When there is only one person to select I still need to assign the hardcoded value 'TRUE' to the People[i].IsSelected property to satisfy my validation.

How can I do that?

@if (hasMoreThanOnePerson)
{
    <td>
        @Html.CheckBoxFor(m => m.People[i].IsSelected)
    </td>
}
else
{
    @Html.HiddenFor(m => m.People[i].IsSelected, true) // Set TRUE always to hidden field within for loop with indexer
}

解决方案

Use htmlAttributes to set value property of Hidden Field using this overload or this overload:

@Html.HiddenFor(m => m.People[i].IsSelected, new {Value="true"})

It will output html like:

<input id="YourModel.People[0].IsSelected" 
       name="YourModel.People[0].IsSelected" 
       type="hidden" 
       value="true">
