Getting the value as object object

[JPSS]

Client Script

function onLoad() {

    var sap = new GlideAjax('ProcessTraining');

    sap.addParam('sysparm_name','closecategory');

    sap.getXML(categorycallback)

   function categorycallback(answer) {

    g_form.addInfoMessage(answer);

        answer = JSON.parse(answer); // parse answer

        alert("Answer: " + answer);

        tlist=answer.split(",");

}

}//Type appropriate comment here, and begin script below

Script Include

var ProcessTraining = Class.create();

ProcessTraining.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    closecategory: function(){

        var category_arr=[];

            var category=new GlideRecord("u_choice_list");

     category.addEncodedQuery("u_type=service_catalog^u_parent.u_parent.u_choice_value=Tech^u_parent.u_choice_value=HR");

            category.query();

        while(category.next()){

            category_arr.push(category.sys_id);

        }

        gs.addInfoMessage(category_arr.toString());

    return category_arr.toString();

    },

    type: 'ProcessTraining'

});

Coud you please help on this. i am getting the answer as [object][object]

You need to force the u_choice_list sys_id to a string when you push it to the array, or you will get an array of the same sys_id, and it would be best to explicitly join the array on the return so you can control the format:

var ProcessTraining = Class.create();
ProcessTraining.prototype = Object.extendsObject(AbstractAjaxProcessor, {
       
    closecategory: function(){
        var category_arr=[];
        var category=new GlideRecord("u_choice_list");
category.addEncodedQuery("u_type=service_catalog^u_parent.u_parent.u_choice_value=Tech^u_parent.u_choice_value=HR");
        category.query();
        while (category.next()) {
            category_arr.push(category.sys_id.toString());
        }
        gs.addInfoMessage(category_arr.toString());
        return category_arr.join(',');
     },
    type: 'ProcessTraining'});

Since this is a simple array, there's no JSON / parsing, in the client script you would just split the answer if you want an array, and you are missing a key line of code to get the answer from the GlideAjax:

function onLoad() {
    var sap = new GlideAjax('ProcessTraining');
    sap.addParam('sysparm_name','closecategory');
    sap.getXML(categorycallback):

    function categorycallback(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        g_form.addInfoMessage(answer);
        tlist=answer.split(",");
    }
}
