MVC 4 动作链接弹出框确认删除？

Question

单击操作链接执行删除时，执行确认弹出的最佳方法是什么？目前，当我按下删除操作链接时，它将直接删除。无论如何要执行一个弹出确认框来删除？ 谢谢！

我的观点：

  <td>
      @Html.ActionLink("Delete", "SURV_Question_Delete", "SURV_Question", new { Question_ID = Model[i].Question_ID }, null)
  </td>

我的控制器：

 public ActionResult SURV_Question_Delete(int Question_ID)
        {

            var query = from r in db.SURV_Question_Ext_Model.ToList()
                        where r.Qext_Question_ID == Question_ID
                        select r;

            foreach(var item in query)
            { 
                db.SURV_Question_Ext_Model.Remove(item);
                db.SaveChanges();
            }

            return RedirectToAction("SURV_Main_Edit", "SURV_Main", new { id = surveyId });
        }

Answer 1

首先，您的删除操作应该是 POST，而不是 GET。您的修改数据，不希望将其添加到浏览器历史记录中，或允许在地址栏中输入 url（该项目可能已被删除）

将您的 html 更改为

@using (Html.BeginForm("SURV_Question_Delete", "SURV_Question", new { Question_ID = Model[i].Question_ID }))
{
  @Html.AntiForgeryToken()
  <input type="submit" value="delete" />
}

并使用[HttpPost] 和[ValidateAntiForgeryToken] 属性装饰方法。

然后添加一个脚本

$('form').submit(function() {
  // Modify the following to use you jquery-ui-dialog, but for testing purposes
  if (!confirm("Are you sure want to delete record") { 
    return false; // cancel the submit if the user clicked the Cancel button
  }
});

Answer 2

试试这样，在调用javascript函数的链接上添加在线确认。

 @Html.ActionLink("Delete", "SURV_Question_Delete", "SURV_Question",
 new { Question_ID = Model[i].Question_ID, onclick = "return 
                                            DeleteConfirm()" }, null)


 function DeleteConfirm() 
    {
        if (confirm("Are you sure want to delete record"))
            return true;
        else
            return false;        
    }

你也可以试试这个

@Html.ActionLink("Delete", "SURV_Question_Delete", "SURV_Question",
     new { Question_ID = Model[i].Question_ID,  onclick="return confirm('Are you sure?');"},null);

您还可以执行以下操作，这将显示确认框 要删除的值，在 删除。

@Html.ActionLink("Delete Subject", "DeleteSubject", "Subjects", new { SubjectId = _item.SubjectMsId }, new { onClick = "return confirm('Are you sure, you want to Delete the Subject : "+ @_item.SubjectName+" ?')" })
