如何在 ASP.NET MVC 中的 HTML-5 data-* 属性中使用破折号 [英] How to use dashes in HTML-5 data-* attributes in ASP.NET MVC

问题描述

我正在尝试在我的 ASP 中使用 HTML5 数据属性.NET MVC 1 项目.(我是 C# 和 ASP.NET MVC 新手.)

I am trying to use HTML5 data- attributes in my ASP.NET MVC 1 project. (I am a C# and ASP.NET MVC newbie.)

 <%= Html.ActionLink("« Previous", "Search",
     new { keyword = Model.Keyword, page = Model.currPage - 1},
     new { @class = "prev", data-details = "Some Details"   })%>

上述htmlAttributes中的data-details"报错如下:

The "data-details" in the above htmlAttributes give the following error:

 CS0746: Invalid anonymous type member declarator. Anonymous type members 
  must be declared with a member assignment, simple name or member access.

当我使用 data_details 时它有效，但我想它需要按照规范以data-"开头.

It works when I use data_details, but I guess it need to be starting with "data-" as per the spec.

我的问题:

• 有没有什么办法可以让这个工作并使用 HTML5 数据属性与 Html.ActionLink 或类似的 Html 助手?
• 是否有其他替代机制可以将自定义数据附加到元素?此数据稍后由 JS 处理.

推荐答案

更新:MVC 3 和更新版本对此有内置支持.有关推荐的解决方案，请参阅下面 JohnnyO 高度赞成的答案.

我不认为有任何直接的帮助可以实现这一目标，但我确实有两个想法供您尝试:

I do not think there are any immediate helpers for achieving this, but I do have two ideas for you to try:

// 1: pass dictionary instead of anonymous object
<%= Html.ActionLink( "back", "Search",
    new { keyword = Model.Keyword, page = Model.currPage - 1},
    new Dictionary<string,Object> { {"class","prev"}, {"data-details","yada"} } )%>

// 2: pass custom type decorated with descriptor attributes
public class CustomArgs
{
    public CustomArgs( string className, string dataDetails ) { ... }

    [DisplayName("class")]
    public string Class { get; set; }
    [DisplayName("data-details")]
    public string DataDetails { get; set; }
}

<%= Html.ActionLink( "back", "Search",
    new { keyword = Model.Keyword, page = Model.currPage - 1},
    new CustomArgs( "prev", "yada" ) )%>

只是想法，还没有测试过.

Just ideas, haven't tested it.
