Question

我是编程的新手，自2月以来我基本上都在尝试自学。我已经设法使用Visual Studio / MVC5创建了一个基本的表单，但我正在努力解决一些更复杂的功能问题。

这里我有一个禁用的复选框（id = withdrawn），我希望它在启用'update'（id = update）复选框后启用。我还希望仅在勾选相同的“更新”复选框时才显示“RefNumber”文本框。任何帮助将不胜感激。

@model F10New.ViewModels.NewSubmissionForm
@{
ViewBag.Title = "NewSubmission";
Layout = "~/Views/Shared/_Layout.cshtml";
}


@using (Html.BeginForm("Save", "Notifications"))

{

<p>*Is this the initial notification of the project p>

<div class="form-inline">
<div class="checkbox" id="initialNotification">
    <label>
        @Html.CheckBoxFor(m => m.Notification.Intial, new { @enabled   = "enabled" }) Initial notification        </label>
</div>    
<div class="checkbox" id="update">
    <label>
        @Html.CheckBoxFor(m => m.Notification.Update) Update to an existing notification
    </label>
</div>

    <div class="checkbox" id="withdrawn">                       
        <label>
            @Html.CheckBoxFor(m => m.Notification.Withdrawn, new { @disabled = "disabled" }) The project has been withdrawn
        </label>
    </div>    

<b>Details of the locations(s) of the site</b>

}

Answer 1

包括jquery然后

<script>
  $(document).ready(function(){
     $("#Notification_Update").on('change', function(){
         $("#Notification_Withdrawn").removeAttr("disabled");
         $("#my_hidden_input_id").show();

      });
  });
</script>

更新

使用HTML帮助程序将自定义ID添加到HTML控件。

@Html.CheckBoxFor(m => m.Notification.Withdrawn, 
   new { @disabled = "disabled", @id="Withdrawn" }) 

@Html.CheckBoxFor(m => m.Notification.Update, 
   new { @id="Update" })

使用复选框“启用”另一个复选框＆amp;显示隐藏的文本框
