I am creating a gym membership form - it will offer two different types of memberships at 3 different locations.
All of these options could be housed in a drop down - or not.
Once the user has selected their membership option I will need to add together a couple of lines of fees : so a start up fee + admin fee + (1week of cost+remaining number of days of cost in the week of purchase)
The start up fee and admin fee are known costs $99 and $49. 1 week costs=$10.99. So the mathematical formula in the brackets would be ( if purchased on a sat) $10.99+(10.99*6)/7
The form is a basic payment form other than these calculations.
var date = new Date();
var today = date.getDay();
var daily = 10.99/7;
var days = [1, 7, 6, 5, 4, 3, 2];
// select the tag with the the id Amount
var x = document.getElementById('Amount');
// insert the value into the input
x.value = parseFloat(99 + 49 + (daily * days[today])+10.99).toFixed(2)
I have this so far and it's working...
But I need each of the amounts for : admin, start up and pro rata to be fed into their input fields on change - the change being the user's selection of this type of membership or another that doesn't have a start up fee ( so exactly the same but 0=start up fee)
