这是我的代码:
模型:
[Required]
[DataType(DataType.Text)]
[Display(Name = "Your company's name")]
public string CompanyName { get; set; }
视图:
@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input", @placeholder = @Html.DisplayNameFor(m => m.CompanyName), @id = "companyname" })
将呈现:
贵公司'的名字
HTML输出:
<input class="account-input" data-val="true" data-val-required="The Your company's name field is required." id="companyname" name="CompanyName" placeholder="Your company&#39;s name" type="text" value="">
它应该是这个样子:
您的公司名称
为什么文字不能正确渲染,我怎样才能避免这种情况?
我已经尝试过这样的:
@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input", @placeholder = @Html.Raw(@Html.DisplayNameFor(m => m.CompanyName)), @id = "companyname" })
还有这个
@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input", @placeholder = @Html.Encode(@Html.DisplayNameFor(m => m.CompanyName)), @id = "companyname" })
我觉得这篇文章将帮助你:
HTML编码解码C#MVC4
我认为有其他的方式来获得这种行为,但是这是使用文本框的一个选项:
@Html.TextBox("CompanyName", HttpUtility.HtmlEncode("Your company's name"))
还有HttpUtility.HtmlDecode
,这可能与我们攒动的帮助。
更新
如果您包装HttpUtility.HtmlDecode
周围的占位符:
@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input",
@placeholder = HttpUtility.HtmlDecode(Html.DisplayNameFor(x => x.CompanyName).ToHtmlString()),
@id = "companyname" })
占位符的返回:占位符=“您的公司名称”
这里有一个帮手displayplaceholderfor将出现占位符不进行编码。

public static partial class Extensions
{
public static MvcHtmlString DisplayPlaceHolderFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
{
var result = html.DisplayNameFor(expression).ToHtmlString();
return new MvcHtmlString(System.Web.HttpUtility.HtmlDecode(result.ToString()));
}
}
那岂不是更容易地就跳过使用Html.DisplayNameFor? 解码和重新编码的文字,似乎不需要的。
public static MvcHtmlString DisplayPlaceHolderFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
{
var metaData = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
var resolvedDisplayName = metaData.DisplayName ?? metaData.PropertyName;
if (!string.IsNullOrEmpty(resolvedDisplayName))
return new MvcHtmlString(resolvedDisplayName);
var htmlFieldName = ExpressionHelper.GetExpressionText(expression);
resolvedDisplayName = htmlFieldName.Split('.').Last();
return new MvcHtmlString(resolvedDisplayName);
}
