Saving a JavaScript Value to a SAS Global Variable

[DavidPhillips2]

I’ve been researching how to integrate SAS and JavaScript.

Is there a way to set a SAS variable equal to JavaScript variable in SAS 9.2?  I have a stored process inside of Information Delivery Portal using a Web URL that displays a stored process inside a webpage like setup.  I found that SAS can use HTML variables when the user clicks refresh so long as the variables are Global Variables.  Changing the HTML variable changes the SAS variable. I want to access one of the Global variables via JavaScript so that I can reference the value when the page reloads. I only need the JavaScript to extract the value of:

$(""#degStudLev"").multipleSelect('getSelects');

Is there a way extract this value as html or assign it to a Global SAS variable?

The code concept is:

%Global degStudLev degStudLevComma;

/*degStudLev is assigned a value*/

%macro javaScriptFunctions;

            data _null_ ;

             file _webout ;

             put '<script type="text/JavaScript">' ;

            put "function saveMultiSelection() {";

                        put "alert('Selected values: ' + $(""#degStudLev"").multipleSelect('getSelects'));";

/*this is the line doesn't save the variable back to SAS Global Variable degStudLevComma.*/

                        put "var degStudLevComma = $(""#degStudLev"").multipleSelect('getSelects');";

            put "}";

%mend;

%javaScriptFunctions;

If the multiple selection is a List Box when you submit the form it is converted to multiple macro variables in SAS.

If not a List Box, how about you save to a hidden text input, when your form is submited you get the value on SAS as a macro variable.

The hidden textbox should work.  Currently doing a proof of concept.

How about using HttpRequestObject (Ajax) to interact with SAS and using Sessions to keep the Variable Value between interactions?
