In this article I will explain with an example, how to use AngularJS in ASP.Net MVC.
The Controller Action method will be called using AngularJS $http service with AJAX and JSON from View in ASP.Net MVC.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 

Model

The Model class consists of the following porperties.
public class PersonModel
{
    ///<summary>
    /// Gets or sets Name.
    ///</summary>
    public string Name { get; set; }
 
    ///<summary>
    /// Gets or sets DateTime.
    ///</summary>
    public string DateTime { get; set; }
}
 
 

Controller

The Controller consists of following Action methods.

Action method for handling GET operation

Inside this Action method, simply the View is returned.
 

Action method for handling POST operation

This Action method handles the call made from the AngularJS AJAX function from the View.
Note: The following Action method handles POST call and will return JSON object and hence the return type is set to JsonResult.
 
The value of the name parameter is assigned to the Name property of the PersonModel object along with the Current DateTime.
Finally, the PersonModel class object is returned back as JSON to the AngularJS AJAX function.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public JsonResult AjaxMethod(string name)
    {
        PersonModel person = new PersonModel
        {
            Name = name,
            DateTime = DateTime.Now.ToString()
        };
        return Json(person);
    }
}
 
 

View

Inside the View, the following AngularJS script file is inherited.
1. angular.min.JS
 
The HTML of the View consists of:
DIV – For applying ng-app and ng-controller AngularJS directives.
Note: If you want to learn more about these directives, please refer my article Introduction to AngularJS.
 
TextBox – For capturing user input.
The HTML TextBox has been assigned with an AngularJS ng-model directive.
Note: If you want to learn more about ng-model directive, please refer my article Using ng-model directive in AngularJS.
 
Button – For displaying records.
The HTML INPUT Button has been assigned with the following AngularJS directive.
ng-click – Called when user clicks the Button.
When the Button is clicked, the ButtonClick function is executed.
Note: If you want to learn more about ng-click directive, please refer my article AngularJS: Implement Button click event using ng-click directive example.
 
Inside the ButtonClick function, the $http service is used to make an AJAX call to the Controller’s Action method. The $http service has following properties and event handlers.

Properties

1. method – The method type of HTTP Request i.e. GET or POST. Here it is set to POST.
2. url – URL of the Controller’s Action method.
3. datatype – The format of the data i.e. XML or JSON. Here it is set as JSON.
4. data – The parameters to be sent to the Controller’s Action method.
5. headers – List of headers to be specified for the HTTP Request.
 

Event Handlers

1. success – This event handler is triggered once the AJAX call is successfully executed.
2. error – This event handler is triggered when the AJAX call encounters an error.
The response from the AJAX call is received in JSON format inside the Success event handler of the $http service and the result is displayed using JavaScript Alert Message Box.
