JavaScript Alert Message On Conditional Bases In Asp.Net MVC Using C#.Net

This article will show you how you can display alert message on conditional bases using JavaScript in asp.net mvc application and c#.net. This article we can use in MVC2, MVC3, MVC4,MVC5.

Some of my previous articles are as follows: Javascript Confirm Message On Submit Button Click In Asp.Net MVC Using C#.Net, Dynamic Histogram Google Chart in asp.net MVC using C#.net, JavaScript, Dynamic Google Geo Chart In an Asp.Net MVC Using C# and Javascript, Gridview Selected Row Value Pass to JavaScript Function On Hyperlink Click in Asp.net Using C#.Net, Access Session Value at Client Side Using JavaScript In Asp.Net.

So for this article first we will create a new asp.net mvc application and add the below code into your controller.

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace MvcApplication2.Controllers {     public class HomeController : Controller     {         //         // GET: /Home/         public ActionResult Index()         {             return View();         }         [HttpPost]         public ActionResult Index(string Type)         {             ViewBag.Message = Type;             return View();         }     } }

In above code please check the httpost attribute method parameter.  In this I have passed a parameter Type this is the dropdown list value which I am storing in viewbag and passing it to view for displaying the value on conditional bases.

Now create view and add the below code in the view.

@{     ViewBag.Title = "JavaScript Alert Message On conditional Bases In Asp.Net MVC Using C#.Net"; } <script>     function Msg1() {         alert("This is alert message Section - 1");     }     function Msg2() {         alert("This is alert message Section - 2");     } </script> @using (Html.BeginForm("Index", "Home")) {    <select name="Type">    <option value="1">Message 1</option>    <option value="2">Message 2</option>    </select>     <input type="submit" value="Submit"/>      if (ViewBag.Message == "1")     {     <script type>         Msg1();     </script>     }      else if (ViewBag.Message == "2")      {      <script>          Msg2();     </script>      } }

In above code I have created to simple JavaScript function with alert message, and on the bases of view bag value I am executing the JavaScript function.

Now check the output.
