在创造HtmlButtonExtension MVC3剃须刀错误 [英] MVC3 razor Error in creating HtmlButtonExtension

问题描述

我试图使用此创建我的网页上的自定义HTML按钮

I am trying to create a custom html button on my page using this

public static class HtmlButtonExtension 
{
  public static MvcHtmlString Button(this HtmlHelper helper, string text,
                                     IDictionary<string, object> htmlAttributes)
  {
      var builder = new TagBuilder("button");
      builder.InnerHtml = text;
      builder.MergeAttributes(htmlAttributes);
      return MvcHtmlString.Create(builder.ToString());
  }
}

当我点击这个按钮，我想一个recordId所传递给我的动作

When I click this button I want to pass an recordID to my Action

下面给出的是什么，我加入到我的Razor视图

Given below is what I added to my razor view

@ Html.Button（删除，新名称{=的CustomButton的recordId =1}）

@Html.Button("Delete", new {name="CustomButton", recordID ="1" })

但我不能得到显示这个按钮，它的投掷误差修改

But I could not get to display this button,and it's throwing erros

'System.Web.Mvc.HtmlHelper<wmyWebRole.ViewModels.MyViewModel>' does not contain a definition for 'Button' and the best extension method overload 'JSONServiceRole.Utilities.HtmlButtonExtension.Button(System.Web.Mvc.HtmlHelper, string, System.Collections.Generic.IDictionary<string,object>)' has some invalid arguments

有人可以帮我找出实际误差

Can some one help me to identify the actual error

推荐答案

您正在传递一个匿名对象，而不是一个的IDictionary＆LT;字符串对象＆gt; 为 htmlAttributes 。

You're passing an anonymous object, not an IDictionary<string, object> for htmlAttributes.

您可以添加使用对象htmlAttributes 额外的过载。这是他们如何做到在内置的ASP.NET MVC HTML辅助：

You can add an additional overload with object htmlAttributes. This is how they do it in the built-in ASP.NET MVC Html Helpers:

public static class HtmlButtonExtension 
{    
  public static MvcHtmlString Button(this HtmlHelper helper, string text,
                                     object htmlAttributes)
  {
      return Button(helper, text, HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes));
  }

  public static MvcHtmlString Button(this HtmlHelper helper, string text,
                                     IDictionary<string, object> htmlAttributes)
  {
      var builder = new TagBuilder("button");
      builder.InnerHtml = text;
      builder.MergeAttributes(htmlAttributes);
      return MvcHtmlString.Create(builder.ToString());
  }

}
