MVC遇上bootstrap后的ajax表单模型验证

MVC遇上bootstrap后的ajax表单验证

 

使用bootstrap后他由他自带的样式has-error,想要使用它就会比较麻烦,往常使用jqueyr.validate的话只有使用他自己的样式了,而且有模型在使用模型验证更方便点。怎么解决呢?

当然你可以专门写一个针对此的jquery插件,我觉得蛮麻烦的,喜欢写插件的研究下吧。

 

首先Nuget获取一个 MVC EditorTemplates for Bootstrap 3 的组件,有了他以后就有了一些模版,比如比较简单的一个Text

 

@model object

<div class="form-group@(Html.ValidationErrorFor(m => m, " has-error"))">

    @Html.LabelFor(m => m, new { @class = "control-label" })

    <div class="controls">

        @Html.TextBox(

            "",

            ViewData.TemplateInfo.FormattedModelValue,

            ViewBag.ClearTextField == true ? new { @class = "form-control clear-text-field input-block-level" } : new { @class = "form-control input-block-level" } )

        @Html.ValidationMessageFor(m => m, nullnew { @class = "help-block" })

    </div>

</div>

 

这样子以后在使用EditorFor后就会直接输出bootstrap需要的html,比较方便。

 

我们看到里面已经有了验证失败的has-error的处理,第二个问题来了,我们需要前端验证,ajax验证也行啊,还有自定义验证呢?

 

于是乎继续利用MVC自带的模型验证,刚才获取的组件中有个Validation类,我们先在里面添加一个扩展方法用于非强类型

        public static MvcHtmlString ValidationError(this HtmlHelper htmlHelper, string field, string error)

        {

            if (HasError(htmlHelper, ModelMetadata.FromStringExpression(field, htmlHelper.ViewData), field))

                return new MvcHtmlString(error);

            else

                return null;

        }

View中即可添加:

        <div class="form-group@(Html.ValidationError("Department"" has-error"))">

            <label class="control-label" for="DepartmentId">所在部门</label>

            <div class="controls">

                <span id="deptname"> </span><a id="btnSelectDepartment">选择部门</a>

                <input class="form-control" data-val="true" data-val-required="部门是必需的。" id="DepartmentId" name="DepartmentId" type="hidden" value="">

                @Html.ValidationMessage("Department"nullnew { @class = "help-block" })

            </div>

        </div>

 

最后在脚本中处理ajax提交和回发的处理,不知道用MVCAjax.BeginForm能不能更方便点,不过个人觉得这东西不是很灵活,所以继续ajaxSubmit及jquery.ajax

//ready

            var $divuserform = $("#divuserform");

            $divuserform.dialog({

                title: '新建用户',//.....

            });

            $("#btnCreateUser").click(function () {

                var nodes = zTreeObjleft.getSelectedNodes();

                if (nodes.length > 0) {

                    CreateUserForm($divuserform);

                }

            })

 

 

function CreateUserForm(form) {

            var $divuserform = form;

            $.ajax({

                url: "CreateUser",

                success: function (html) {

                    CreateUserFormSuccessCallback(html, $divuserform);

                }

            });

        }

 

        function InitSelectDepartmentWhenCreateUser() {

            $("#btnSelectDepartment").departmentSelection({

                onSelected: function (name, id) {

                    $("#deptname").text(name);

                    $("#DepartmentId").val(id);

                }

            });

        }

 

        function CreateUserFormSuccessCallback(html, form) {

            var $divuserform = form;

            $divuserform.children().children().html(html);

            $("#divuserform").dialog("open");

            var $form = $divuserform.find("form")

            InitSelectDepartmentWhenCreateUser();

            $form.submit(function () {

                $form.ajaxSubmit(function (data) {

                    if (data == "success") {

                        $("#divuserform").dialog("close");

                        $("#divuserform").clearForm();

                    }

                    else {

                        CreateUserFormSuccessCallback(data, form);

                    }

                });

                event.preventDefault();

            });

        }

 

后台Action方法中我们便可为其补充自定义验证:

            if (!DepartmentId.HasValue)

            {

                ModelState.AddModelError("Department""必须选择部门");

            }

 

            if (ModelState.IsValid)

            {

                user.Id = Guid.NewGuid();

                user.CreateTime = DateTime.Now;

                if (DepartmentId.HasValue)

                {

                    var dept = new DeptUserRole();

                    dept.DepartmentId = DepartmentId.Value;

                    dept.IsMain = true;

                    dept.RoleId = RoleId.Value;

                    user.DeptUserRoles.Add(dept);

                }

                db.Users.Add(user);

                await db.SaveChangesAsync();

                return Content("success");

            }

 

            return View(user);

 

大致效果
