Asp net core pass data from ajax to view

Introduction

ASP.NET is a popular programming language used for building web applications. One common task in web is passing data from the -side to the server-side. In this article, we will explore how to pass data from AJAX to a view in ASP.NET Core.

Step 1: AJAX Request

To pass data from AJAX to a view, we first need to set up an AJAX request in our client-side code. Here is an example of how to do this:


$.ajax({
  url: "/Controller/Action",
  type: "POST",
  data: { key: value },
  : function(response) {
    // Handle the response from the server
  },
  error: function(xhr, status, error) {
    // Handle any errors that occur during the AJAX request
  }
});

In the above code, we make a POST request to the specified URL (“/Controller/Action”) and pass the data as key-value pairs. The success and error handle the response from the server and any errors that occur during the request, respectively.

Step 2: Define Controller Action

Next, we need to define a controller action in our ASP.NET Core to handle the AJAX request. Here is an example of how to do this:


[HttpPost]
 IActionResult Action(string key)
{
  //  the data received from the AJAX request
  return View();
}

In the above code, we define a controller action with the [HttpPost] attribute to indicate that it should handle POST requests. The action takes a parameter (in this case, a string named “key”) to receive the data passed from the AJAX request. the action, we can process the data as needed and return a view.

Step 3: Render View with Data

Finally, we need to render a view with the data received from the AJAX request. Here is an example of how to do this:


@ string

Data from AJAX Request

@Model

In the above code, we define a view with a model of type string. We can then access the data passed from the AJAX request using the @Model directive. In this example, we simply display the data in a heading and paragraph element.

Conclusion

Passing data from AJAX to a view in ASP.NET Core is a common task in web development. By following the steps outlined in this article, you can easily accomplish this task and render views with the data received from AJAX requests.
