Question

我的cshtml文件中有很多@Html.EditorFor个像这样的对象：

@Html.EditorFor(m => product.size_L, new { htmlAttributes = new { @class = "form-control size_L calculateOffer acceptIntegerOnly", @tabIndex = "1", @autocomplete = "off" } })

我需要为某些EditorFor对象添加@readonly = "readonly"属性，但仅针对其中一些对象，仅在product.enableReadonly == true时。

当然，我可以这样做：

@if (product.enableReadonly)
{
    @Html.EditorFor(m => product.size_L, new { htmlAttributes = new { @class = "form-control size_L calculateOffer acceptIntegerOnly", @tabIndex = "1", @autocomplete = "off" } })
}
else
{
    @Html.EditorFor(m => product.size_L, new { htmlAttributes = new { @class = "form-control size_L calculateOffer acceptIntegerOnly", @tabIndex = "1", @autocomplete = "off", @readonly="readonly" } })
}

但它看起来并不好看。当我有更多那些＆＃34;可选＆＃34;要添加的属性？代码会扩展得更多。

那么，您能想到一些智能，紧凑的解决方案吗？

这是来自内存，但是为了清理我的巨大EditorFor调用，我创建了一些这样的重载方法：

public static MvcHtmlString EditorFor<TModel, TItem>(this HtmlHelper<TModel> html, Expression<Func<TModel, TItem>> expr, bool readOnly)
{
            if (readOnly)
            {
                return html.EditorFor(expr, new
                {
                    htmlAttributes = new
                    {
                        @class = "form-control size_L calculateOffer acceptIntegerOnly",
                        tabIndex = "1",
                        autocomplete = "off",
                        @readonly = "readonly"
                    }
                });
            }

            return html.EditorFor(expr, new
            {
                htmlAttributes = new
                {
                    @class = "form-control size_L calculateOffer acceptIntegerOnly",
                    tabIndex = "1",
                    autocomplete = "off"
                }
            });
 }

有条不紊地向EditorFor添加属性的好看方式
