ASP MVC Razor 对输入占位符中的特殊字符进行编码

问题描述

这是我的代码:

型号:

[Required]
[DataType(DataType.Text)]
[Display(Name = "Your company's name")]
public string CompanyName { get; set; }

查看:

@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input", @placeholder = @Html.DisplayNameFor(m => m.CompanyName), @id = "companyname" })

它将呈现如下:

贵公司的名称

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&amp;#39;s name" type="text" value="">

应该是这样的:

贵公司名称

为什么文本无法正确呈现，我该如何防止?

Why is the text does not render correctly and how can I prevent this?

我已经试过了:

@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" })

推荐答案

我认为这篇文章会对你有所帮助:

我认为还有其他方法可以获得这种行为，但这是使用 TextBox 的一种选择:

I think there are other ways to get this behaviour, but this is one option of using the TextBox:

@Html.TextBox("CompanyName", HttpUtility.HtmlEncode("Your company's name"))

还有 HttpUtility.HtmlDecode，它可能有助于我们的保存操作.

There is also HttpUtility.HtmlDecode, which might help with our save action.

更新

如果将 HttpUtility.HtmlDecode 包裹在占位符周围:

if you wrap HttpUtility.HtmlDecode around your place holder:

@Html.TextBoxFor(m => m.CompanyName, new { @class = "account-input",
@placeholder = HttpUtility.HtmlDecode(Html.DisplayNameFor(x => x.CompanyName).ToHtmlString()),
@id = "companyname" })

占位符返回为:placeholder="贵公司名称"

the placeholder returns as: placeholder="Your company's name"
