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

Hi Rams,

Thank you for the update.

$('quantity').value is not working in Portal though

Hi Preethi,

I was able to fix this and is working fine for me as intended.

Do the following in "SC Shopping Cart" widget

Server script: 

var userID = gs.getUser().getID();
//var cart = new SPCart(input.cartName, userID);
var cart = new SPCart_Custom(input.cartName, userID);
data.Flag = false;
data.quantities = {};
data.quantity = 0;
data.FIL = 0;

var gr = new GlideRecord('custom table');
if(gr.get('u_user', gs.getUserID())){
data.FIL = gr.getValue('custom field');
}
if (input && input.action === "error") {
data.quantity = input.tempQuantity;
data.quantities = JSON.parse(JSON.stringify(input.tempQuantities));
data.Flag = data.Flag;
gs.addErrorMessage('You have exceeded your ordering limit');
return;

Client script: AT checkout

c.triggerCheckout = function($evt, twostepCheckout) {
if(c.data.Flag && c.data.FIL >= 0 && c.data.quantity > c.data.FIL)
{
c.data.tempQuantities = JSON.parse(JSON.stringify(c.data.quantities));
c.data.tempQuantity = c.data.quantity;
c.data.tempFlag = c.data.Flag;
c.data.action = 'error';
c.server.update().then(function(response) {
c.data.action = null;
});
