Use addToCart() function from sn_sc.CartJS() to add multiple items into the cart.Issue 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 Log in to any out-of-box instance as System Administrator (Or any user with admin role).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); } //************************************************************ 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.) Delete all the sc_cart records for the current user.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.ReleaseLondon , OrlandoRelated LinksCartJS (Developer docs)
