【问题描述】:
我正在尝试让我的客户端验证(模型绑定)以支持不同的文化,并且我发现了一个关于我正在尝试实施的主题的有趣博客。

波科
public class Jogador
{
public int ID { get; set; }
public string Name { get; set; }
public decimal Salary { get; set; }
}
我有我的自定义 DecimalModelBinder 类
public class DecimalModelBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
ValueProviderResult valueResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
ModelState modelState = new ModelState {Value = valueResult};
object actualValue = null;
try
{
actualValue = Convert.ToDecimal(valueResult.AttemptedValue, CultureInfo.CurrentCulture);
}
catch (FormatException e)
{
modelState.Errors.Add(e);
}
bindingContext.ModelState.Add(bindingContext.ModelName, modelState);
return actualValue;
}
}
我的 web.config:
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

<add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</assemblies>
</compilation>
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="2880" />
</authentication>
<pages>
<namespaces>
<add namespace="System.Web.Helpers" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="System.Web.WebPages"/>
</namespaces>
</pages>
Global.asax 已更改为在十进制和十进制上使用我的自定义 ModelBinder?价值观
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());
ModelBinders.Binders.Add(typeof(decimal?), new DecimalModelBinder());
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
客户端验证仍然失败,在我的视图中输入小数点时使用“,”作为小数点分隔符。它不能同时处理“,”和“.”。 js 验证似乎没有考虑我的自定义绑定
一遍又一遍地阅读博客文章,我似乎无法弄清楚我错过了什么。
这里是视图:
@model MVC_Empty.Web.Models.Jogador
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
<legend>Jogador</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Salary)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Salary)
@Html.ValidationMessageFor(model => model.Salary)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
服务器端验证看起来不错,但是如何处理客户端验证以便在单击提交按钮时发送 POST。
javascript 验证不处理逗号。
