Question

我有一个视图索引和一个部分视图SCItems。我使用数据注释进行验证。它适用于Index，但不适用于我的部分SCItem。我应该使用jquery验证？谢谢。 SCModel代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
using System.Web.WebPages.Html;

namespace PunchClockMobile.Models
{
    public class SCModel
    {
        public List<string> scList = new List<string>();

        [Required(ErrorMessage = "SC ID cannot be empty!")]
        public string scID { get; set; }

        [StringLength(4, ErrorMessage = " Please use 4 characters ")]
        [Range(0, 24, ErrorMessage = " Please use 0-24 range ")]
        [Required(ErrorMessage = "Please enter work duration")]
        public double? Duration { get; set; }

        [Required(ErrorMessage = "Please select a date")]
        public DateTime? Date { get; set; }

        [Required(ErrorMessage = "No task selected!")]
        private List<SelectListItem> _task = new List<SelectListItem>();

        [Required(ErrorMessage = "No task selected!")]
        public string SelectedTask { get; set; }

        [Required(ErrorMessage = "No task selected!")]
        public List<SelectListItem> Task
        {
            get { return _task; }
        }

    }
}

索引代码：

@model PunchClockMobile.Models.SCModel
@{
    ViewBag.Title = "SC Number";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@section Header {
    <h3 style="text-align: left; padding-left: 1px;">
        SC Number</h3>
}
<div data-role="content" class="ui-content" role="main">
    @using (Html.BeginForm())
    {  <fieldset>
          <div data-role="fieldcontain">
        <label class="select">
            SC Number:</label>
        @Html.TextBoxFor(m => m.scID, new { @data_inline = true, @Class = "scIDFormat" })
        <br />
        <br />
        @Html.ValidationMessageFor(m => m.scID)
        <button type="submit" id="scOK" name="scOK">
            OK</button>
        </div>
        <div id="scList">
        </div>
      </fieldset>
       }
    </div>

<script language="javascript" type="text/javascript">

    $(document).ready(function () {
 $("#scOK").click(function () {

            if ($("form").valid()) {
                GetSCItems();
                $("#scList").show();
            }
            return false;
        });
 function GetSCItems() {
        var action = '@Url.Action("GetSCItems", "SCNumber")';
        var scID = $("#scID").val();
        var opt = {
            type: "GET",
            data: { ID: scID },
            url: action,
            success: SCListSuccess,
            error: SCListFailed
        };
        jQuery.ajax(opt);
    }

    function SCListSuccess(data) {
        if (data != undefined) {
            $('#scList').html(data).trigger('create');
            $("#noValues").hide();
        }
        else {
            //error
        }
    }

    function SCListFailed() {
        //error
    }
   });
</script>

MVC 3 Razor. Partial View validation is not working

在MVC3中，部分视图的返回类型是“ MVCHTMLString ”，我们可以在服务器端捕获此字符串并对其应用验证。在您的控制器中

 protected string RenderPartialViewToString(string viewName, object model)
        {
            if (string.IsNullOrEmpty(viewName))
                viewName = ControllerContext.RouteData.GetRequiredString("action");

            ViewData.Model = model;

            using (StringWriter sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
                ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
                viewResult.View.Render(viewContext, sw);
                return sw.GetStringBuilder().ToString();
            }
        }

通过将ViewName和Model传递给此方法，它将返回视图的“ MVCHTMLString ”，因此可以在模型中应用验证。并使用Ajax.BeginForm而不是Html.BeginForm来提交局部视图。所以在你的paratil视图中

      @using (Ajax.BeginForm("GetSCItems", "SCNumber", new AjaxOptions { OnSuccess = "AddSearch", UpdateTargetId = "scList" }))
     {
        <input type="submit" value="save"/>
     }

在控制器

中

public ActionResult GetSCItems(SCModel model)
{
     // operation 
     return RenderPartialViewToString("SCItems",model)
}

AjaxOption中的

将“ UpdateTargetId ”指定为scList，其结果将附加到其中。

部分视图中的MVC3客户端验证
