MVC3,Ajax和具有客户端不显眼验证的模态形式

标签: asp.net-mvc-3 asp.net-ajax modal-dialog jqmodal unobtrusive-validation

我无法将标题中的内容组合在一起工作。我已经阅读了各种问题但未找到涵盖我正在尝试的所有问题的问题。

我正在使用jqModal作为我的模态窗口。我正在使用Ajax.BeginForm。我的模型装饰有[Required][Display(...)]等。

这些内容全部放在使用@Html.RenderAction(...)

的网页上

取决于我是否在ajax调用中使用OnBeginOnComplete,我要么没有得到客户端验证(更新只是没有),要么模态陷入状态在没有对话框的情况下整个页面被“修改掉”的地方。但实际上我想要的是,如果存在客户端或服务器端验证错误,模式将保持不变。

如果没有javascript可用/启用,该网站不需要任何功能。

模特:

public class ReplacedTextModel {
    public ReplacedTextModel() { }
    public ReplacedTextModel(int id, string text, string replaced) {
        Id = id;
        Text = text;
        Replaced = replaced;
    }
    public int Id { get; set; }
    [Required, Display(Description = "The text of the question", Prompt = "Please enter the question text."), UIHint("MultilineString")]
    public string Text { get; set; }
    public string Replaced { get; set; }
}

编辑器模板(这包含一些扩展方法,但它们与问题无关,所以请忽略):

@model string
<div class="form-element">
  @Html.Label("", new Dictionary<string, object> { { "title", Html.Description("") } })
  @if (Html.IsRequired()) { 
    <span class="form-required">*</span>
  }
  <div class="form-control">
    @Html.TextArea("", Model, new Dictionary<string, object> { { "title", Html.Prompt("") } })    
    <div class="form-validation">
      @Html.ValidationMessage("")    
    </div>
  </div>
</div>

视图(页面上可能有很多这些视图,并且可能会重复这些视图,所以我使用Guids来表示唯一性):

@model ReplacedTextModel
@{ 
  var id = Guid.NewGuid().ToString("N");
  var windowId = "id_" + id + "_window";
  var triggerId = "id_" + id + "_trigger";
  var replaceId = "id_" + id + "_replace";
  var functionId = "id_" + id + "_closeForm";
}
<div id="@replaceId">
  @Html.Raw(Model.Replaced)
  <span class="edit-mode"><a id="@triggerId" href="#">edit</a></span>
  <div id="@windowId" class="jqmWindow" style="display: none">
    @using (Ajax.BeginForm("Text", new AjaxOptions { UpdateTargetId = replaceId, OnBegin = functionId, HttpMethod = "POST" })) { 
      @Html.HiddenFor(x => x.Id)
      @Html.EditorFor(x => x.Text)
      <input type="submit" value="Save" />
    }
    <div><a href="#" class="jqmClose">Cancel</a></div>
  </div>
  <script type="text/javascript">
    $(function () { $("#@windowId").jqm({ trigger: "#@triggerId" }); });  
    function @(functionId)() {     
      // THIS IS A PROBLEM
      // if it's not called or is called on OnBegin then the modal doesn't close properly
      // if OnComplete is used, the dialog disappears but the validation doesn't work
      // in either case, validation failure on backend (try posting whitespace) doesn't show validation errors.    
      $("#@windowId").jqmHide(); 
    };
  </script>
</div>

控制器方法:

    public ActionResult Text(int id) {
        return PartialView("Text", ReplacedTextModel.Get(id));
    }

    [HttpPost]
    public ActionResult Text(int id, string text) {
        if (ModelState.IsValid) {
            try {
                if (string.IsNullOrWhiteSpace(text)) throw new ArgumentException("No text was provided for the question.", "text");
                ReplacedTextModel.Update(id, text);
            } catch (Exception ex) {
                ModelState.AddModelError(ex);
            }
        }
        return Text(id);
    }

对不起,很长的帖子,但我看到其他人提到这不是一件坏事!很高兴在需要时发布任何其他代码/信息。我可能已经遗漏了一些东西,因为我已经从项目中的几个位置进行了复制/粘贴。

提前致谢。
