This article shows the use of the addToCart() function to add multiple items into the current user's cart.

It is working as expected to call sn_sc.CartJS() multiple times in the script to be able to add multiple items.

Procedure

1. Log in to any out-of-box instance as System Administrator (Or any user with admin role).
2. Go to System Definition > Script - Background. And test the following script:
   

   //************************************************************ 
   var cart = new sn_sc.CartJS();
   for (i = 0; i < 2; i++) {
     gs.addInfoMessage('i: '+ i);
     var item = {
       'sysparm_id': '10a2f5dfc6112276018db58138c7a1e0', //sys_id of catalog item
       'sysparm_quantity': '1',
       'variables': {
       },
     };
     cart.addToCart(item);
   }
   //************************************************************

3. We are expecting two items to be added to the user's cart, but if you check the sc_cart record for the current user, only one item got added.
   • (To find current user's sc_cart records, type sc_cart.list in the instance menu Filter navigator.
   • Filter the resulting list on the User column.)
4. Delete all the sc_cart records for the current user.
5. Test the following script in System Definition > Script - Background again:
   

   //************************************************************ 
   for (i = 0; i < 2; i++) {
     gs.addInfoMessage('i: '+ i);
     var cart = new sn_sc.CartJS();
     var item = {
       'sysparm_id': '10a2f5dfc6112276018db58138c7a1e0',
       'sysparm_quantity': '1',
       'variables': {
       },
     };
     cart.addToCart(item);
   }
   //************************************************************

   
   Note "var cart = new sn_sc.CartJS();" is inside the loop now. This script adds two items into the cart.
