Using Ajax while saving

[Farai]

Can anyone give me a simple example of using ajax to save with parameters using PDF Viewer. I noticed while reading the API docs something called  AjaxRequestSettings. Can anyone give me an execution example?

I have seen somewhat of an example but do not have the full picture.

AjaxRequestSettings is used to set the custom AJAX request header values of the PDF Viewer AJAX requests. If you want to send the custom JSON data in the AJAX request parameter while saving the document or any other request, use the below code snippet.

Code Snippet:

    function ajaxRequestInitiate(args) {

        var viewer = document.getElementById('pdfviewer').ej2_instances[0];

        if (args.JsonData['action'] == 'Download') {

            args.JsonData['name'] = "Syncfusion";

            args.JsonData['userId'] = "User1";

            viewer.setJsonData(args.JsonData);

        }

    }
