MVC C# 模式弹出窗口 [英] MVC C# modal popup

问题描述

好的，所以我正在尝试找出如何根据这篇文章的建议使用控制器为我的页面正确调用模式弹出窗口

ok so i'm trying to figure out how to properly call a modal popup for my page using Controllers as per this post's suggestion

ASP.NET MVC 模态对话框/弹出窗口最佳实践

有点用这个:

http://microsoftmentalist.com/2011/09/14/asp-net-mvc-13-open-window-or-modal-从控制器方法弹出并填充它的内容/

我有一个包含下拉列表的视图，如果用户找不到他/她正在寻找的项目/值，他可以建议一个应该调用控制器并返回的值(建议新值链接)一个弹出页面，其中包含几个字段.

I have a view that has a dropdownlist, if the user can't find the item / value that he/she is looking for he can suggest a value (suggest new value link) which is supposed to call the controller and return a popup page with a couple of fields in it.

这是视图上的对象:

<script type="text/javascript">

        loadpopup = function () 
        {  
window.showModalDialog(‘/NewValue/New′ , "loadPopUp", ‘width=100,height=100′); 
        } 

    </script> 


<%: Html.DropDownList(model => model.ValueId, new selectlist........... %>
<%: Html.ActionLink("Suggest Value", "New", "NewValue", null, new { onclick = 'loadpopup()') %>

我打算用来返回页面的控制器:

The controller that I'm planning to use to return the page:

public class NewValueController : Controller{
   public Actionresult New(){
      return View();
   }
}

现在我被困住了.我想返回一个可以格式化的页面，我必须返回一个字符串吗?我不能返回一个 aspx(我使用的引擎)，因为格式化会更容易吗?

Now I'm stuck. I wanted to return a page where I can format it, do i have to return a string ? can't i return an aspx (engin i use) instead, since formatting that would be easier?

非常感谢任何关于我应该去哪个方向的建议.

Any advice as to which direction i should go is very much appreciated.

谢谢！

推荐答案

你可以使用 jquery UI Dialog 用于弹出窗口.让我们在这里做一个小设置.

You could use the jquery UI Dialog for the popup. Let's have a small setup here.

我们会有一个主窗体的视图模型:

We would have a view model for the main form:

public class MyViewModel
{
    public string ValueId { get; set; }
    public IEnumerable<SelectListItem> Values 
    { 
        get 
        {
            return new[]
            {
                new SelectListItem { Value = "1", Text = "item 1" },
                new SelectListItem { Value = "2", Text = "item 2" },
                new SelectListItem { Value = "3", Text = "item 3" },
            };
        } 
    }

    public string NewValue { get; set; }
}

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return Content("thanks for submitting");
    }
}

和一个视图(~/Views/Home/Index.aspx):

<%@ Page 
    Language="C#" 
    MasterPageFile="~/Views/Shared/Site.Master" 
    Inherits="System.Web.Mvc.ViewPage<AppName.Models.MyViewModel>" 
%>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>
        <%= Html.DropDownListFor(x => x.ValueId, Model.Values) %>
        <br/>
        <%= Html.EditorFor(x => x.NewValue) %>
        <%= Html.ActionLink("Suggest Value", "New", "NewValue", null, new { id = "new-value-link" }) %>
        <button type="submit">OK</button>
    <% } %>

    <div id="dialog"></div>

</asp:Content>

然后我们可以处理弹出窗口.我们为它定义一个视图模型:

then we could take care for the popup. We define a view model for it:

public class NewValueViewModel
{
    public string Foo { get; set; }
    public string Bar { get; set; }
}

控制器:

public class NewValueController : Controller
{
    public ActionResult New()
    {
        return PartialView(new NewValueViewModel());
    }

    [HttpPost]
    public ActionResult New(NewValueViewModel model)
    {
        var newValue = string.Format("{0} - {1}", model.Foo, model.Bar);
        return Json(new { newValue = newValue });
    }
}

以及对应的局部视图(~/Views/NewValue/New.ascx):

and a corresponding partial view (~/Views/NewValue/New.ascx):

<%@ Control 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewUserControl<AppName.Models.NewValueViewModel>" 
%>

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "new-value-form" })) { %>
    <%= Html.EditorFor(x => x.Foo) %>
    <%= Html.EditorFor(x => x.Bar) %>
    <button type="submit">OK</button>
<% } %>

现在剩下的就是编写一些 javascript 来连接所有内容.我们包括 jquery 和 jquery ui:

Now all that's left is to write a bit of javascript to wire everything up. We include jquery and jquery ui:

<script src="<%: Url.Content("~/Scripts/jquery-1.5.1.min.js") %>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/jquery-ui-1.8.11.js") %>" type="text/javascript"></script>

还有一个包含我们代码的自定义 javascript 文件:

and a custom javascript file that will contain our code:

$(function () {
    $('#new-value-link').click(function () {
        var href = this.href;
        $('#dialog').dialog({
            modal: true,
            open: function (event, ui) {
                $(this).load(href, function (result) {
                    $('#new-value-form').submit(function () {
                        $.ajax({
                            url: this.action,
                            type: this.method,
                            data: $(this).serialize(),
                            success: function (json) {
                                $('#dialog').dialog('close');
                                $('#NewValue').val(json.newValue);
                            }
                        });
                        return false;
                    });
                });
            }
        });
        return false;
    });
});
