如何使用@Html.NopEditorFor添加占位符

$(document).ready(function() {
  $('#YourEditorFieldId').attr('placeholder', 'Your Placeholder Text');
});

using System;
using System.Linq.Expressions;
using System.Web.Mvc;
using System.Web.Mvc.Html;

public static class HtmlExtensions
{
    public static MvcHtmlString NopEditorForWithPlaceholder<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression, string placeholder)
    {
        var editorHtml = htmlHelper.NopEditorFor(expression);
        var editorString = editorHtml.ToString();
        var placeholderAttribute = string.Format("placeholder=\"{0}\"", placeholder);

        if (editorString.Contains("<textarea"))
        {
            editorString = editorString.Replace("<textarea", "<textarea " + placeholderAttribute);
        }

        return MvcHtmlString.Create(editorString);
    }
}

@Html.NopEditorForWithPlaceholder(model => model.Content, "Enter your content here...")
