How to get Shopping Cart Quantity in Catalog client script

[Manoj82]

Hi All,

 I am trying to get the value of shopping cart Quantity on to a catalog client script.

Requirement: Prior to Checkout, I need to identify the quantity in the cart and compare with another field "Free items" on a different table in ServiceNow instance

Based on the result, If Quantity in Cart >Free items then the user should not able to Checkout. If Freeitems >Quantity in Cart user should be able to checkout.

I have written a Catalog Client script to retrieve the values from Cart and a Script include to compare.

In the Client Script used below script Quantity value from the Shopping Cart using :
ga.addParam('sysparm_quantity', $('quantity').value); (with GlideAjax)

Even tried just an alert to check i.e. alert("('quantity').value: " + $('quantity').value); in Service portal a Java Script Error in Browser Console Error is coming. Heard "$" is an unsupported method in Portal

Can someone help me how to get Quantity value so that I can call from my Client script and compare in my Script include with my "Free Items" field

Regards,
Manoj

You may need to query the sc_cart_item table to get the quantity.

[SatheeshKumar]

use the below code to get the cart item quantity:

var cartId = new sn_sc.CartJS().getCartID();
var quantity =0;
var item = new GlideRecord('sc_cart_item');
item.addQuery('cart', cartId);
item.query();
while(item.next()){
	quantity=   quantity+ item.quantity;
}

gs.print(quantity);

Asynchronous GlideAjax does not work in onSubmit client script. Is there a way to get the quantity value in onSubmit client script through Service Portal?
