将Twitter引导与Asp.net MVC 3表单集成
我正在使用Asp.NETMVC3和Twitter引导。我想要的是将两者结合起来。对我来说最大的问题是形式。我使用的是将Twitter引导与Asp.net MVC 3表单集成,asp.net,twitter-bootstrap,forms,asp.net-mvc-3,unobtrusive-validation,Asp.net,Twitter Bootstrap,Forms,Asp.net Mvc 3,Unobtrusive Validation,我正在使用Asp.NETMVC3和Twitter引导。我想要的是将两者结合起来。对我来说最大的问题是形式。我使用的是HtmlHelper，这是一个问题，当涉及到验证时，我希望它生成如下HTML： <div class="control-group error"> <label for="field" class="control-label">OMG this label is so awesome: </label> <div class=
HtmlHelper<div class="control-group error">
<label for="field" class="control-label">OMG this label is so awesome: </label>
<div class="controls">
<input type="text" name="field" id="field" value="yeah" />
<span class="help-inline">Eventually some error :C</span>
</div>
</div>
问题是，我希望仅当此字段上确实存在错误时，才设置最外层div上的类错误。另一个问题是，我不知道如何强制对错误使用span标记。我可以用HtmlHelper编写我的方法，但这会使我重新实现
LabelFor编辑器For验证消息For<div class="control-group @if (!ViewData.ModelState.IsValidField("Name")) { @Html.Raw("error"); }">
@Html.LabelFor(model => model.Name, new {@class = "control-label"})
<div class="controls">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name, null, new {@class = "help-inline"})
</div>
</div>
整个项目的源代码很快就可以使用了（请参阅我的个人资料，或者直接询问我）。我冒昧地创建了一个扩展方法，它封装了Sherbrow的代码，以便在字段无效时呈现错误类。此扩展方法的优点是它是强类型的，并且编写时间更短：
public static MvcHtmlString ModelStateFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
{
var modelMetadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
if (html.ViewData.ModelState.IsValidField(modelMetadata.PropertyName))
{
return MvcHtmlString.Empty;
}
return new MvcHtmlString("error");
}
public static MvcHtmlString ModelStateFor（此HtmlHelper html，表达式）
{
var modelMetadata=modelmetada.FromLambdaExpression（表达式，html.ViewData）；
if（html.ViewData.ModelState.IsValidField（modelMetadata.PropertyName））
{
返回MvcHtmlString.Empty；
}
返回新的MvcHtmlString（“错误”）；
}

从Bootstrap 3（和TwitterBootstrapMVC 3）开始，TwitterBootstrapMVC需要使用许可证。我不知道这是否对任何人都有帮助，但我修改了M$的jquery.validate.unobtrusive.js来实现这一点。它覆盖了$.validator.setDefaults（）提供的默认设置，给我带来了问题。 如果您用这个文件替换JS文件，它应该可以像您希望的那样使用bootstrap的CSS（不需要其他更改-除了输入元素和标签上的一些CSS类） $jQval.setDefaults（）是主要内容。剩下的就是我在修改M$的代码 文件如下：
