How to caluclate the amount based labels values Count

The logic I explained you can do in javascript too.

I don't have the ready-made code for you.

If you go with the latest answer given by me you will have lot less complexity and finer code.

Instead of depending on the text of the label you should maintain a counter for selection of the seat.

So if user selects a seat you increament the counter and if user unselects the seat you decrease the counter.

And to calculate the total fare by multiplying farePerSeat by the counter.

I want this action in javascript

It should not be based on the label text but it should be based on the count.

To simplify you can split the label text by comma. that will give you array of strings.

You use length of the array to calculate the final fare.

There is a way better approach you can take to count the selected seats and calculate the total fare.
