<div class="alert">
    نمایش اعلانات
</div>

تعدادی کلاس دیگر نیز جهت استفاده از رنگ‌های مختلف نیز توسط بوت استرپ ارائه شده است: 

همچنین اگر مایل بودید می‌توانید با افزودن یک دکمه با کلاس close و ویژگی data-dismiss مساوی alert، امکان بستن پیام را در اختیار کاربر قرار دهید: 

<div class="alert alert-warning alert-dismissable">
  <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
  نمایش اعلان
</div>

در ادامه قصد داریم این پیام را بعد از ثبت اطلاعات، به کاربر نمایش دهیم. یعنی در داخل کد، امکان صدا زدن این نوع پیام‌ها را داشته باشیم.

ابتدا کلاس‌های زیر را تعریف می‌کنیم:

کلاس Alert

public class Alert
{
        public const string TempDataKey = "TempDataAlerts";
        public string AlertStyle { get; set; }
        public string Message { get; set; }
        public bool Dismissable { get; set; }
}

در کلاس فوق خصوصیت یک alert را تعریف کرده‌ایم (از خاصیت TempDataKey جهت پاس دادن alert‌ها به view استفاده می‌کنیم).

public class AlertStyles
{
        public const string Success = "success";
        public const string Information = "info";
        public const string Warning = "warning";
        public const string Danger = "danger";
}

public class BaseController : Controller
{
        public void Success(string message, bool dismissable = false)
        {
            AddAlert(AlertStyles.Success, message, dismissable);
        }

        public void Information(string message, bool dismissable = false)
        {
            AddAlert(AlertStyles.Information, message, dismissable);
        }

        public void Warning(string message, bool dismissable = false)
        {
            AddAlert(AlertStyles.Warning, message, dismissable);
        }

        public void Danger(string message, bool dismissable = false)
        {
            AddAlert(AlertStyles.Danger, message, dismissable);
        }

        private void AddAlert(string alertStyle, string message, bool dismissable)
        {
            var alerts = TempData.ContainsKey(Alert.TempDataKey)
                ? (List<Alert>)TempData[Alert.TempDataKey]
                : new List<Alert>();

            alerts.Add(new Alert
            {
                AlertStyle = alertStyle,
                Message = message,
                Dismissable = dismissable
            });

            TempData[Alert.TempDataKey] = alerts;
        }
}

جمع بندی 

در صورتیکه این کد بد بو اصلاح شود، معمولا با کدی قابل درک‌تر و با سازماندهی منطقی بهتری روبرو خواهیم بود. به طور کلی رعایت رابطه منطقی بین کلاس‌ها، علاوه بر جلوگیری از بروز مشکل «میراث رد شده»، خوانایی کد را افزایش داده و اعمال تغییرات در آن را نیز آسان‌تر می‌کند.

به ازای هر آیتمی که در شیء بازگشتی وجود دارد، با استفاد از متد each در jQuery یک li ایجاد می‌کنیم. همان طور که می‌بینید کلیه خواص، به شکل Fluent قابل اضافه شدن می‌باشد. سپس برای li یک رویداد کلیک که در صورت وقوع، متد FillData را با شناسه فید کلیک شده فراخوانی می‌کند و در آخر li را به المنت ul اضافه می‌کنیم.

برای هر کلیک هم مانند مثال بالا api را با شناسه‌ی فید مربوطه فراخوانی کرده و به ازای هر آیتم، یک سطر ایجاد می‌کنیم.
