In my previous articles of MVC you might be noticed that while inserting the data into database whole post back is happened . So to avoid it in this article we will learn how to post the data using jQuery Ajax post method in MVC which will insert the data asynchronously without whole page post back .
So let's demonstrate it by using simple MVC application.
Step 1 : Create an MVC Application.
Now let us start with a step by step approach from the creation of simple MVC application as in the following:
Right click on model folder of created MVC application project and add class named Empmodel.cs
Empmodel.cs
Step 2 : Add Controller
HomeController.cs
Step 3: Add View
Right click on View folder of created MVC application project and add empty view named AddEmployee.cshtml
Step 4: Create Jquery Post method
Now open the AddEmployee.cshtml view and create the following JQuery Post method to call controller .
Note
or you can use offline jQuery file .
Now after adding the library and form controls the AddEmployee.cshtml code will be look like as
Now everything is ready ,run the application and enter the details into the following form .
After entering the details click on save button then the details will be get added into the database as
From all above example we have learned how to insert the data using JQuery post method without whole page post back.
Note
So let's demonstrate it by using simple MVC application.
Step 1 : Create an MVC Application.
Now let us start with a step by step approach from the creation of simple MVC application as in the following:
- "Start", then "All Programs" and select "Microsoft Visual Studio 2015".
- "File", then "New" and click "Project..." then select "ASP.NET Web Application Template", then provide the Project a name as you wish and click on OK .
Right click on model folder of created MVC application project and add class named Empmodel.cs
Empmodel.cs
public class EmpModel { public string Name { get; set; } public string City { get; set; } public string Address { get; set; } }
HomeController.cs
public class HomeController : Controller { private SqlConnection con; // GET: Home public ActionResult AddEmployee() { return View(); } //Post method to add details [HttpPost] public ActionResult AddEmployee(EmpModel obj) { AddDetails(obj); return View(); } //To Handle connection related activities private void connection() { string constr = ConfigurationManager.ConnectionStrings["SqlConn"].ToString(); con = new SqlConnection(constr); } //To add Records into database private void AddDetails(EmpModel obj) { connection(); SqlCommand com = new SqlCommand("AddEmp", con); com.CommandType = CommandType.StoredProcedure; com.Parameters.AddWithValue("@Name", obj.Name); com.Parameters.AddWithValue("@City", obj.City); com.Parameters.AddWithValue("@Address", obj.Address); con.Open(); com.ExecuteNonQuery(); con.Close(); } }
Right click on View folder of created MVC application project and add empty view named AddEmployee.cshtml
Step 4: Create Jquery Post method
Now open the AddEmployee.cshtml view and create the following JQuery Post method to call controller .
<script> $(document).ready(function () { $("#btnSave").click(function () { $.ajax( { type: "POST", //HTTP POST Method url: "Home/AddEmployee", // Controller/View data: { //Passing data Name: $("#txtName").val(), //Reading text box values using Jquery City: $("#txtAddress").val(), Address: $("#txtcity").val() } }); }); }); </script>
- To work with jQuery we need to reference of jQuery library .You can use following CDN jQuery library
or you can use offline jQuery file .
Now after adding the library and form controls the AddEmployee.cshtml code will be look like as
@{
ViewBag.Title = "www.compilemode.com";
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function () {
$("#btnSave").click(function () {
$.ajax(
{
type: "POST", //HTTP POST Method
url: "Home/AddEmployee", // Controller/View
data: { //Passing data
Name: $("#txtName").val(), //Reading text box values using Jquery
City: $("#txtAddress").val(),
Address: $("#txtcity").val()
}
});
});
});
</script>
<br /><br />
<fieldset>
<div class="form-horizontal">
<div class="editor-label">
Name
</div>
<div class="editor-label">
<input type="text" id="txtName" />
</div>
<div class="editor-label">
Address
</div>
<div class="editor-label">
<input type="text" id="txtAddress" />
</div>
<div class="editor-label">
City
</div>
<div class="editor-label">
<input type="text" id="txtcity" />
</div>
<div class="editor-label">
<br />
<input class="btn-default" type="button" id="btnSave" value="Save" />
</div>
</div>
</fieldset>
From all above example we have learned how to insert the data using JQuery post method without whole page post back.
Note
- Do a proper validation such as date input values when implementing.
- Make the changes in the web.config file depending on your server details for the connection string.
Summary
From all the preceding examples you have learned how to insert the data using JQuery post method. I hope this article is useful for all readers, if you have a suggestion then please contact me.
