How to get the service catalog cart sys_id of an attachment

varaprasad123 · ‎04-30-2020

Hello,

I am trying to enforce attachment mandatory based on the variable field value selected on a catalog item. I am using the following script include and catalog client script, unfortunately, I am getting cart id as a "null".
Is there any method to retrieve cart_id, or any corrections to below script is much appreciated.

Script Include:

var getAttachmentAjax = Class.create();
getAttachmentAjax.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getAttachment: function() {
var client_table_name = this.getParameter('sysparm_table_name');
var client_sys_id = this.getParameter('sysparm_sys_id');
var grAttachment = new GlideRecord('sys_attachment');
grAttachment.addEncodedQuery('table_name=' + client_table_name + '^table_sys_id=' + client_sys_id);

// grAttachment.addQuery("table_name", client_table_name);
// grAttachment.addQuery("table_sys_id", client_sys_id);
grAttachment.query();
if (!grAttachment.next()) {
return 'false';
} else {
return 'true';
}
},
type: 'getAttachmentAjax'
});

On Change client script

var cart_sys_id = '';

if (newValue == 'true') {

var gaAttachmentData = new GlideAjax('global.getAttachmentAjax');
gaAttachmentData.addParam('sysparm_name', 'getAttachment');
gaAttachmentData.addParam('sysparm_sys_id',cart_sys_id);

gaAttachmentData.addParam('sysparm_table_name', 'sc_cart_item');
gaAttachmentData.getXMLAnswer(AttachmentData);
}
}

function AttachmentData(answer) {
// console.log(answer);
if (answer != 'false') {
g_form.setValue('variable_checkbox', true);
g_form.showFieldMsg('variable_checkbox', 'It looks like you attached X attachments.', 'info');

} else {
g_form.setValue('variable_checkbox', false);
g_form.showFieldMsg('variable_checkbox', 'It seems you forgot your attachments.', 'error');

}
