With that amount of information, there is no way we can help you. What have you already tried? And what exactly does not work?

Thanks for update and tried below logic and it's not working. Can you help where exactly i was missing the logic?

Client Script :--------------------

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var ga = new GlideAjax("checkUser");

    ga.addParam("sysparm_name", "getUsers");

    ga.addParam("sysparm_value", g_form.getValue("user_check"));

    ga.getXML(userCheck);

    function userCheck(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");

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

        if(answer.includes("albert")){

            g_form.setMandatory("Requester",true);

        }

    }

}

Script Include ------------------

var checkUser = Class.create();

checkUser.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUsers: function() {

        var checkValues = this.getParameter("sysparm_value");

        //var arr = checkValues(",");

        //for (var i = 0; i < arr.length; i++) {

            var croles = new GlideRecord('sys_user');

            croles.addQuery('sys_id', checkValues);

            croles.query();

            var arrRoles = [];

            if (croles.next()) {

                gs.info("*******Users" + croles.getDisplayValue());

                //Fill array

                //var arr =croles.split(",");

                arrRoles.push(croles.getDisplayValue().toString());

            //}

        }

        return arrRoles.toString();

    },

    type: 'checkUser'

});

Thanks,

Nagesh

What is your script supposed to do? What exactly does not work?
