Question

I have a ASP.NET MVC application which has a view populated with a model which needs to retrieve some data from the user. Besides that, I also have a hidden div tag which contains more information but it should be visible only after the model was sent to the controller on a POST request and after it has processed the information from the model it should change the div tag to visible. Is some way to signal the view that the request was processed and render visible the div tag, remaining on the same page. I believe this is similar to a partial postback from ASP.NET.

Thanks,

Yes that’s possible via some AJAX functionality. I’m using jQuery in my example:

$.post('Controller/Action', $('#formId').serialize(), function() {
  $('#yourDiv').show();
});

This uses jQuery to post the data contained in a form with the HTML id ‘formId’ to a URL ‘Contoller/Action’ and shows the div with id ‘yourDiv’ in case the AJAX request finished successfully. The call $(‘#formId’).serialize encodes the form elements in HTML form with id formId for submission in the AJAX request.
