How to get the returned value to client script

[Anna_Servicenow]

I have the below script, How can I get the value back to client script and set it in form section

var AttachmentParse = Class.create();

AttachmentParse.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    process: function() {

        var currentSysId = this.getParameter('sysparm_sys_id');

        gs.log("currentSysId: " + currentSysId);

        var attachment = new GlideSysAttachment();

        var getdata = new GlideRecord('sys_attachment');

        getdata.addQuery('table_sys_id', currentSysId);

        getdata.addQuery('table_name', "ZZ_YYu_bpm");

        getdata.query();

        if (getdata.next()) {

            gs.log("loop");

            var attachmentSysID = getdata.sys_id.toString();

            var attachmentStream = attachment.getContentStream(attachmentSysID);

            var demodata = new sn_impex.GlideExcelParser();

            demodata.parse(attachmentStream);

            var caseID = [];

            var resolvedBy = [];

            var headers = demodata.getColumnHeaders();

            var header1 = headers[0];

            var header2 = headers[1];

            while (demodata.next()) {

                var row = demodata.getRow();

                caseID.push(row[header1]);

                resolvedBy.push(row[header2]);

            }

            gs.info("Case ID: " + caseID);

            gs.info("Resolved By: " + resolvedBy);

I think your issue is you have 2 Array and how to return them both 

You can make array or Array or JSON here

Eg

var AttachmentParse = Class.create();
AttachmentParse.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    process: function() {
        var currentSysId = this.getParameter('sysparm_sys_id');
        gs.log("currentSysId: " + currentSysId);
        var attachment = new GlideSysAttachment();
        var getdata = new GlideRecord('sys_attachment');
        getdata.addQuery('table_sys_id', currentSysId);
        getdata.addQuery('table_name', "ZZ_YYu_bpm");
        getdata.query();
        if (getdata.next()) {
            gs.log("loop");
            var attachmentSysID = getdata.sys_id.toString();
            var attachmentStream = attachment.getContentStream(attachmentSysID);

            var demodata = new sn_impex.GlideExcelParser();
            demodata.parse(attachmentStream);

            var caseID = [];
            var resolvedBy = [];
var finalArr = [];
            var headers = demodata.getColumnHeaders();
            var header1 = headers[0];
            var header2 = headers[1];
            while (demodata.next()) {
                var row = demodata.getRow();
                caseID.push(row[header1]);
                resolvedBy.push(row[header2]);
            }
finalArr[0] = caseID.toString();
finalArr[1] = resolvedBy.toString();
            gs.info("Case ID: " + caseID);
            gs.info("Resolved By: " + resolvedBy);
return finalArr;
}
}

I could get the value in client script, how can I set it to form section like below. ( we have this in place already and we enter the value manually, now I want the returned value to be set here automatically.) @Anurag Tripathi

Hey Ana, This is an embedded list, which means this data is on another table and has a reference to current table.

You can't add or modify data here through client script. 

I would suggest you do this on the script include itself writing a GlideRecord on this table and updating the record.

On the client script you can just reload the form.
