How to get the selected cart line on the Button Click

Hi All,

I have a requirement to apply a gender based discount like line discount. I have created a button in the POS. On the select of this i am able to get the whole cart details instead of the selected cart line.

By using this below code I am able to get the whole cart details

let cartRequest: CartOperations.GetCurrentCartClientRequest<CartOperations.GetCurrentCartClientResponse> =
new CartOperations.GetCurrentCartClientRequest();

// Get cart first and then find the first available cartline which does not have any discounts applied.
return context.runtime.executeAsync(cartRequest)
.then((result: ClientEntities.ICancelableDataResult<CartOperations.GetCurrentCartClientResponse>): void => {

if (!result.canceled) {
cart = result.data.result;
}
}).then((): CancelableDiscountRequest => {

if (ObjectExtensions.isNullOrUndefined(cart)) {
return <CancelableDiscountRequest>{
canceled: true,
data: null
};
}

Can you please guide me how to get the selected line from the cart?

Hi, you can create an extension of CartView controller - to catch selected lines, save them into global variable - and use this selection in your code. Sample is below (ExtendedSessionInformation.instance in Singleton)

export default class CartViewController extends CartView.CartExtensionViewControllerBase {

public _selectedCartLines: ProxyEntities.CartLine[];

constructor(context: IExtensionCartViewControllerContext) {

super(context);

this.cartLineSelectedHandler = (data: CartView.CartLineSelectedData): void => {

this._selectedCartLines = data.cartLines;

ExtendedSessionInformation.instance.selectedCartLines = data.cartLines;

};

this.cartLineSelectionClearedHandler = (): void => {

this._selectedCartLines = undefined;

ExtendedSessionInformation.instance.selectedCartLines = [];

};
