如何使用EditorFor禁用输入字段的自动完成功能？

Question

<%= Html.EditorFor(product => product.Name) %>

我需要生成的输出设置autocomplete ="off"属性.

我错过了什么？

编辑:我正在寻找一个EditorFor的扩展方法,它接受属性的键/值字典,所以我可以像这样调用它: <%= Html.EditorFor(product => product.Name, new { autocomplete = "off" } ) %>

这是为LabelFor完成的,但需要针对EditorFor进行调整

    public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes) {
        return LabelFor(html, expression, new RouteValueDictionary(htmlAttributes));
    }
    public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, IDictionary<string, object> htmlAttributes)
    {
        ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
        string htmlFieldName = ExpressionHelper.GetExpressionText(expression);
        string labelText = metadata.DisplayName ?? metadata.PropertyName ?? htmlFieldName.Split('.').Last();
        if (String.IsNullOrEmpty(labelText))
        {
            return MvcHtmlString.Empty;
        }

        TagBuilder tag = new TagBuilder("label");
        tag.MergeAttributes(htmlAttributes);
        tag.Attributes.Add("for", html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(htmlFieldName));
        tag.SetInnerText(labelText);
        return MvcHtmlString.Create(tag.ToString(TagRenderMode.Normal));
    }

Edit2:我意识到它不能命名为EditorFor,因为已经存在一个被覆盖的EditorFor,它接受一个匿名类型,请参见http://msdn.microsoft.com/en-us/library/ff406462.aspx ..无论如何,我们可以用不同的名字命名,没有大人物.

public static MvcHtmlString EditorForAttr<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes) {
    return EditorForAttr(html, expression, new RouteValueDictionary(htmlAttributes));
}
public static MvcHtmlString EditorForAttr<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, IDictionary<string, object> htmlAttributes) {
    ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
    string htmlFieldName = ExpressionHelper.GetExpressionText(expression);

    TagBuilder tag = new TagBuilder("input");
    tag.GenerateId(html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(htmlFieldName));
    tag.MergeAttribute("name", htmlFieldName);
    tag.MergeAttribute("type", "text");
    tag.MergeAttribute("value", metadata.Model == null ? "" : metadata.Model.ToString()); // Not sure if this is correct.
    tag.MergeAttributes(htmlAttributes, true);
    return MvcHtmlString.Create(tag.ToString(TagRenderMode.SelfClosing));
}
