Set maximum quantity limit based on cat item

[Wayne Richmond]

I want to set the maximum quantity here:

..based on a custom field I've created on the Catalog Item:

Is there are way to do this? I thought an onLoad Catalog Client Script would allow me to set the options of the choice list, however I'm not sure how to manipulate the values on the table like this. 

At the very least, can I prevent the form being submitted if the selected quantity is more than the value in my custom field?

Thanks all

Hello @Wayne Richmond ,

Try this below code which is used to restrict user from selecting more than 5 as quantity and tweak accordingly.?

Code:

Try adding a client script and script include

Client Script:Cart Limit

Applies to Catalog Item

Type: OnSubmit

Applies on Catalog Item View: true

function onSubmit() {

if (cartLimit(g_user.userID) == false) {

alert("Only 5 items allowed in cart");

}

}

Script Include: CartLimit

Client Callable: true

Script:

function cartLimit(userID){

    var cart = new GlideRecord('sc_cart');

    cart.addQuery('user',userID);

    cart.query();

    if (cart.next()) {

        var cartItem = new GlideRecord('sc_cart_item');

        cartItem.addQuery('cart',cart.sys_id);

        cartItem.query();

        if (cartItem.getRowCount() == 5) {

            return false;

        }

    }

}
