Populate variables in cart api

[HuChin]

Hi all,

I'm tring to populate variables in cart api,

Below is my coding:

var cartId = GlideGuid.generate(null);
var cart = new Cart(cartId);
var item = cart.addItem('e46305bdc0a8010a00645e608031eb0f'); 
cart.setVariable(item,'os','Linux Red Hat');
var rc = cart.placeOrder(); 
gs.addInfoMessage(rc.number);

My question is how to populate a variable in variable set using cart.setVariable() method, thanks in advance!

Use the same approach, when a VarSet is added to a Catalog Item its variables are accessible in the same way as its own.

var cartId = GlideGuid.generate(null);
var cart = new Cart(cartId);
var item = cart.addItem('9aa4f8f1db002010189f2706ca9619ce'); 
cart.setVariable(item,'process','Process 123');
cart.setVariable(item,'source','Source 123');
var rc = cart.placeOrder(); 
gs.addInfoMessage(rc.number);

See the following screenshots

Hi,

Did you try this:

I personally find the newer scoped API is easier to use.

sn_sc.CartJS

var cart = new sn_sc.CartJS();

var item = {
	'sysparm_id': '399ab6812f80ac101c43bed72799b6fa', //sys_id of cat item
	'sysparm_quantity': '1', //Only order 1 RITM

	//Example of how you can populate variables
	'variables':{
		//Left = Variable name
		//Right = Variable value
		'Change': current.getUniqueValue(),
		'Date': new GlideDate().getDisplayValue()
	}
};

cart.addToCart(item); //Add the JSON item above to the cart
var b = cart.checkoutCart(); //Submit the cart
gs.print(JSON.stringify(b)); //the checkout process returns a JSON value containing sys_id and REQ number

If you want to populate a Multi Row Variable Set, you can try this:

var cartId = GlideGuid.generate(null);
var cart = new Cart(cartId);
var item = cart.addItem('e46305bdc0a8010a00645e608031eb0f'); 
cart.setVariable(item,'os','Linux Red Hat');
//Set variables in Multi Row Variable Set
var mrvsArr = [];
//replace question_a with the first variable question_b the second (technical) name of your variable
mrvsArr.push({"question_a" : "answer 1", "question_b" : "answer 1"});
mrvsArr.push({"question_a" : "answer 2", "question_b" : "answer 2"});
var mrvsArrJson = JSON.stringify(mrvsArr);
//change mrvs to the (technical) name of your multi row variable set
cart.setVariable(item, 'mrvs', mrvsArrJson);

var rc = cart.placeOrder(); 
gs.addInfoMessage(rc.number);

To add more you just repeat the line, with different values:

mrvsArr.push({"question_a" : "answer n", "question_b" : "answer n"});
