How to Properly Initiate Ajax Calls in ASP.NET MVC

Making a Simple Ajax Call to Controller in ASP.NET MVC

To initiate Ajax calls in ASP.NET MVC, understanding the interplay between the controller and the view is crucial.

In the provided code snippet, the controller contains an Index action for the view and a FirstAjax action that returns a JSON response containing the string "chamara".

In the view, the jQuery Ajax request is configured to use the "POST" HTTP method and specify the URL to the FirstAjax action. However, the data attribute, set to an empty string, is superfluous since the controller's FirstAjax action does not accept any parameters.

To resolve the issue and fire the alert, remove the data attribute and utilize the Razor syntax to dynamically generate the URL using @Url.Action("FirstAjax", "AjaxTest").

Alternatively, you can modify the controller to define two separate FirstAjax actions, one for GET and one for POST, with different parameters. This approach allows you to have a dedicated action for handling Ajax requests while maintaining the separation of concerns.
