Question

以下是我的代码

在我选择电子邮件ID时的更新选项卡中 - 在返回视图后，它再次设置将标签添加为活动状态（默认情况下它被设置为活动状态）。

如何在选择电子邮件ID后将更新标签设置为有效 - 任何想法。

    <ul class="nav nav-tabs">
    <li role ='presentation' class="active"><a href="#Add" data-toggle="tab">Add</a></li>
    <li role ='presentation'><a href="#Update" data-toggle="tab">Update</a></li>
    <li role ='presentation'><a href="#Delete" data-toggle="tab">Delete</a></li>
    <li role ='presentation'><a href="#menu3" data-toggle="tab">Menu 3</a></li>
</ul>
<div class="tab-content">
    <div id="Add" class="tab-pane active">

基本上你不能那样做，因为你的页面很新鲜。如果你想要那么你需要异步。我的意思是您需要使用@Ajax.BeginForm或jquery/ajax。如果你不想这样做asynchronously，那么就有办法解决。

因此，在从“更新”标签中选择电子邮件后致电action method时，请在 ViewBag 中指定一个值。

例如，在您的操作方法中，

{
 //Rest code
 ViewBag.TabValue = "Update";
 //Rest code
}

现在您可以将此值保留在隐藏字段中。例如，在您的视图中，

<input type="hidden" value="@ViewBag.TabValue" id="myTab"/>

现在，在您的脚本中，您可以检查此值并设置标签，例如

<script>
 if($('#myTab').val() == "Update")
 {
  $("#Update").focus(); //You can add a class as active so on...
 }
</script>
