【问题描述】：

我已经为 cshtml 编写了一个 html 代码，其中包含两个按钮保存和更新：

 <div class="modal-body">
                    @using (Html.BeginForm("Create", "CustomActivity", FormMethod.Post, new  role = "form", @id = "customActivityForm", @class = "activityForm" ))
                    
                        <div>
                            <div class="container" id="activity">
                                @Html.LabelFor(m => m.AdminCustomActivity.Activity, new  @class = "" )
                                @Html.TextBoxFor(m => m.AdminCustomActivity.Activity, new  @class = "w100p mb0" )
                                @Html.ValidationMessageFor(m => m.AdminCustomActivity.Activity, "", new  @class = "text-danger" )
                            </div>

                            <div class="container">
                                <div class="column one-fourth">
                                    <div>
                                        @Html.LabelFor(m => m.AdminCustomActivity.Rate, new  @class = "wcrate" )
                                        @Html.TextBoxFor(m => m.AdminCustomActivity.Rate, new  @class = "w100p mb0" )
                                        @Html.ValidationMessageFor(m => m.AdminCustomActivity.Rate, "", new  @class = "text-danger" )
                                    </div>
                                </div>

                            </div>

                            <div class="modal-footer">
                                @Html.HiddenFor(m => m.AdminCustomActivity.WorkOrderId, new  @id = "hfWorkOrderId" )
                                @Html.HiddenFor(m => m.AdminCustomActivity.Id, new  @id = "customActivityId" )
                                <button type="submit" class="btn btn-primary">Create</button>
                                <button class="btn btn-primary" id="updateActivity">Update</button>
                            </div>
                        </div>

                    
                </div>

现在页脚中有两个按钮添加和更新，验证非常适合添加按钮，但验证不适用于更新按钮，因为更新按钮的函数调用来自 jquery

 $("#updateActivity").click(function () 
                    event.preventDefault();
                    $.ajax(
                        type: "POST",
                        url: "/CustomActivity/Update",
                        data: 
                            WorkOrderId: @Model.Id,
                        ,
                        success: function () 
                            location.reload();
                            window.scrollTo(0, 0);
                        ,
                        error: function () 
                            //alert(erro.data)
                        
                    );
                )

如何允许检查更新按钮中的验证与添加按钮相同。我尝试使用 type='submit' 但这不起作用

【问题讨论】：

@CarstenLøvboAndersen 不，那是剃刀视图中模型的价值，它的作用是``` @Model.Id ```

【参考方案1】：

您必须调用实现jQuery validatation 的函数才能在单击更新按钮时显示验证消息：

function validateUpdate()       
  $("#customActivityForm").validate(
    rules: 
        AdminCustomActivity_Activity: "required",
        AdminCustomActivity_Rate: "required"
     
  );


$("#updateActivity").click(function () 
      validateUpdate();
      $.ajax(
          type: "POST",
          url: "/CustomActivity/Update",
          data: 
              WorkOrderId: @Model.Id,
             ,
          success: function () 
            location.reload();
            window.scrollTo(0, 0);
          ,
          error: function () 
             //alert(erro.data)
          
     );
)

【讨论】：

是它验证必填字段并显示错误消息，但在显示错误消息后它仍然通过ajax调用API。只有在没有任何验证错误的情况下，有没有办法通过ajax调用API？

我用过 if (validateUpdate()) ///ajax call 但没用

我觉得你可以用if($("#customActivityForm").valid())
