【中文标题】如何发回表格?【英文标题】:How to post back form? 【发布时间】:2015-11-09 07:14:57 【问题描述】:我需要使用 Razor 和 Devexpress 控件制作一些表单。当用户打开 Devexpress 弹出控件时,会出现一个包含他需要输入的字段的表单。 这是我的看法:
@model Models.Request
@html.DevExpress().PopupControl(
settings =>
settings.Name = "newRequest";
settings.CallbackRouteValues = new Controller = "Request", Action = "RequestForm" ;
settings.EnableClientSideAPI = true;
settings.Width = 450;
settings.ShowHeader = true;
settings.ShowShadow = true;
settings.PopupAnimationType = AnimationType.Fade;
settings.AllowDragging = true;
settings.Modal = true;
settings.SetContent( () =>
using ( Html.BeginForm( ))
ViewContext.Writer.Write( "<div id = 'products'>" );
foreach(var product in Model.Products)
Html.RenderPartial( "ProductPartial", product );
ViewContext.Writer.Write( "</div>" );
//Total days field
@Html.DevExpress().SpinEdit(
cSettings =>
cSettings.Name = "numberOfProducts";
cSettings.Properties.EnableClientSideAPI = true;
cSettings.Width = 125;
cSettings.Properties.MinValue = 0;
cSettings.Properties.MaxValue = 100;
cSettings.ControlStyle.BackColor = System.Drawing.Color.FromArgb( 82, 82, 82 );
cSettings.ControlStyle.ForeColor = System.Drawing.Color.White;
).Bind( Model.NumberOfProducts ).GetHtml();
//POST BACK
@Html.DevExpress().Button( saveSett =>
saveSett.Name = "Save";
saveSett.Text = "Save";
saveSett.Width = 40;
saveSett.Height = 25;
saveSett.ControlStyle.CssClass = "button";
saveSett.Styles.EnableDefaultAppearance = false;
saveSett.EnableClientSideAPI = true;
saveSett.UseSubmitBehavior = true;
//saveSett.ClientSideEvents.Click = "function(s, e) if(CheckValidation(s, e)) ";
).GetHtml();
);
).GetHtml();
我希望当我的视图被渲染时,它会调用 http get 方法,但事实并非如此,它总是调用用这个定义的 post 方法(如果有相同名称的 get post):
settings.CallbackRouteValues = new Controller = "Request", Action = "RequestForm" ;
为什么会这样?如果我更改 post 方法名称(将在提交时调用),它会给我一个错误,说没有要调用的方法。
此外,我还有我想用于提交表单的按钮: settings.CallbackRouteValues = new Controller = "Request", Action = "RequestForm" ; 但它甚至没有进入控制器中的任何操作方法。为什么会这样?
这是我的操作方法:
public ActionResult RequestForm()
//...
[HttpPost]
public ActionResult RequestForm([ModelBinder(typeof(DevExpressEditorsBinder))] Request request)
//...
如何发回我的模型?最好的方法是什么?显然,它不能以正常方式使用这些 Devexpress 控件。我可以用 jquery 以某种方式发回这个模型吗?什么是最好的方法?请指教。
【问题讨论】:
【参考方案1】:当我想显示带有验证的弹出表单时,我总是使用以下解决方案。首先,我创建的弹出控件一般只使用回调路由值(可选使用 Begin 和 End 回调等属性):
@Html.DevExpress().PopupControl(settings =>
settings.Name = "newRequest";
settings.CallbackRouteValues = new Controller = "Request", Action = "GetRequestForm" ;
//[Optionally]: If you want pass data to action controller or set popup properties
settings.ClientSideEvents.BeginCallback = "myLogic.onBeginActionCallback";
settings.ClientSideEvents.EndCallback = "myLogic.onEndActionCallback";
).GetHtml()
接下来我创建控制器动作:
public ActionResult GetRequestForm()
// … some logic here ...
return PartialView("_PartialView", viewModel);
[HttpPost]
public ActionResult RequestForm([ModelBinder(typeof(MyBinder))] Request request)
// … some logic here ...
return Json(new success = true );
接下来我创建视图(名称:“_PartialView”):
@using (Ajax.BeginForm("RequestForm", "Request",
new AjaxOptions
HttpMethod = "POST" , new id = "saveForm" ))
@Html.DevExpress().TextBox(settings =>
settings.Name = "someProperty";
).GetHtml()
// … other properties…
@Html.DevExpress().Button(settings =>
settings.Name = "SaveButton";
settings.Text = "Save";
settings.ClientSideEvents.Click = "function(s,e) myLogic.saveForm(); ";
settings.UseSubmitBehavior = false;
).GetHtml()
最后我创建了使用 JQuery 验证的 JS 脚本(例如 myLogic.js):
var myLogic = function ()
function saveForm()
var saveForm = $("#saveForm");
saveForm.removeData('validator');
saveForm.validate(validationSettings);
// jQuery validation
$("#someProperty_I").rules("add",
required: true,
// Connect with server example
remote:
url: '/Request/CheckValue',
data:
//.. some logic here ..
,
messages:
required: "Required!",
remote: "Validation message"
);
// and add other jQuery validation
if (saveForm.valid())
saveForm.submit();
var validationSettings =
errorPlacement: function (error, element)
error.appendTo(element.parent("td").parent("tr").parent("tbody").parent("table").parent("td"));
return
saveForm: saveForm
();
当然你应该包含 jQuery 脚本:
1. jquery.validate.min.js
2. jquery.validate.unobtrusive.min.js
