Ajax call on acrobat form by javascript

You can submit form data via FDF or XFDF (or even HTML) and then respond back to the form with FDF or XFDF (in this case, HTML is not an option, that's why I stick with FDF/XFDF both ways). The only drawback is that you can only send and receive information in form fields, so you may need to create some hidden fields that you use just for this type of communication.

Take a look at this for more information: Acrobat DC SDK Documentation - Doc.submitForm()

Thank you so much try67!

I follow the Acrobat JavaScript API Reference to create the following script.js and put it into the folder level folder:

function ajax(cURL) {

    var params =

    {

            cVerb: "GET",

            cURL: cURL,

            oHandler:

            {

                    response: function(msg, uri, e,h){

                            var stream = msg;

                            var string = "";

                            string = SOAP.stringFromStream( stream );

                            app.alert( string );

                    }

            }

    };

    Net.HTTP.request(params);

}

then I create a button on the pdf form and call a javascript: ajax('http://localhost/app/ajaxCall');

But it return this error: NotAllowedError: Security setting prevent access to this property or method.

Any suggestions?
