The below code is working for me

Onchange client script

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

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

        return;   

    }

    if (newValue != oldValue && g_form.getValue('state') != '-5') {

            var catalogItemID = g_form.getUniqueValue();

            //alert('test123' + catalogItemID);

            var demo = new GlideAjax('CheckAttachmentChangeReq');

            demo.addParam('sysparm_name', 'checkAttachment');

            demo.addParam('sysparm_catalog_id', catalogItemID);

            demo.getXML(attr);

    }

function attr(response) {

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

    if (answer == 'yes') {

        alert("Attachment is available now. Thanks!! : " + answer);

        return true;

    } else{

        alert("Attachment is not available!! Please proceed saving the form with the attachment : ");

        //return false;

        g_form.clearValue('end_date');

    }

}

}

Script Include :

var CheckAttachmentChangeReq = Class.create();

CheckAttachmentChangeReq.prototype = Object.extendsObject(AbstractAjaxProcessor, {

 checkAttachment: function() {

        var x = this.getParameter('sysparm_catalog_id');

        gs.log("AG formID"+ x);

        var gr = new GlideRecord("sys_attachment");

        gr.addQuery('table_sys_id', x);

        gr.addQuery('table_name', 'change_request');

        //gr.addQuery('table_sys_id', this.getParameter('sysparm_catalog_id'));

        gr.query();

        if (gr.next()) {

         //   gs.log("Kudos to you!! You have added attachment ");

            return 'yes';

        } else {

         //   gs.log("You must attach document before submitting the form.");

            return 'no';

        }

    },

    type: 'CheckAttachmentChangeReq'

});
