asp.net - MVC 多按钮验证

Question

我在表单上有 4 个按钮，“提交 1”调用 Controller A，“提交 2”调用 Controller B。

我在同一个表单上还有“按钮 1”和“按钮 2”，我不希望对它们进行验证/触发。

如何让“提交 1”和“提交 2”来验证表单而不是“按钮 1”和“按钮 2”？

同时“按钮 1”和“按钮 2”应该提交给不同的 Controller 。我如何实现这一目标？

public class SampleForm
{
    [Display(Name = "FName: ")]
    [Required(ErrorMessage = "Enter FName")]
    public string FirstName { get; set; }

    [Display(Name = "LName: ")]
    [Required(ErrorMessage = "Enter LName")]
    public string LastName { get; set; }

    [Display(Name = "Bypassid: ")]
    [Required(ErrorMessage = "Enter Bypassid")]
    public string Bypassid { get; set; }    
}

@model SampleForm
@using (Html.BeginForm("SampleForm", "SampleController", FormMethod.Post, new { name = "frmSample", id = "frmSample" }))
{
    @Html.LabelFor(model => model.FirstName)
    @Html.TextBoxFor(model => model.FirstName)
    @Html.ValidationMessageFor(model => model.FirstName)

    @Html.LabelFor(model => model.LastName)
    @Html.TextBoxFor(model => model.LastName)
    @Html.ValidationMessageFor(model => model.LastName)

    @Html.LabelFor(model => model.Bypassid)
    @Html.TextBoxFor(model => model.Bypassid)
    @Html.ValidationMessageFor(model => model.Bypassid)

    <input type="submit" value="Submit 1" name="Command" />

    <input type="submit" value="Submit 2" name="Command" />

    <button type="button" name="Button 1" value="Button 1">Button 1</button>

    <button type="button" name="Button 2" value="Button 2">Button 2</button>
}

我希望“提交 1”和“提交 2”使用 DataAnnotations 验证表单，但是当我单击“按钮 1”时，我想确保“Bypassid”字段中有值并重定向到另一个 Controller (比如 .当我点击“按钮 2”时，我不会验证任何内容，只是重定向到另一个 Controller 。

Answer 1

关于提交到两个操作，您有两个提交按钮和独立值的正确想法。您可以使用操作中的值来解读您希望如何处理请求。尽管您在一天结束时只会提交一个操作，但您可以在操作中重定向它以处理流程的差异。例如

@using (Html.BeginForm("BasicAction"))
{
    @* controls *@
    <input type="submit" value="action1" name="command" />
    <input type="submit" value="action2" name="command" />
}

然后，你的 Controller :

[HttpPost]
public ActionResult BasicAction(MyModel model, String command)
{
    if (ModelState.IsValid)
    {
        switch (command)
        {
            case "action1":
                return RedirectToAction("Action1", new { model = model });
            case "action2":
                return RedirectToAction("Action2", new { model = model });
        }
    }
    return View(model);
}

// handle action1
[NonAction]
public ActionResult Action1(MyModel model)
{
    // do whatever
}

[NonAction]
// handle action2
public ActionResult Action2(MyModel model)
{
    // do whatever
}

就禁用验证而言，您可以在按钮 1 和 2 上设置 disableValidation=true，客户端验证将被忽略(我相信这是从 MVC2 开始的)。为此，在定义这些按钮后添加以下 javascript:

<script>
  // IDs of the buttons to be disabled
  var disabled = ['button1','button2'];
  for (var i = 0; i < disabled.length; i++){
      document.getElementById(disabled[i]).disableValidation = true;
  }
</script>
