I am trying to do the below using HTML, CSS and JavaScript:
-
Category (Coffee Appliance) drop down
-
product (Kurig Coffe Maker) drop down
-
Wattage : 1500kWh (pre polulated using Local Storage)
-
Daily Energy Consumption (1,500 W × 1) ÷ 1,000 = 1.5 kWh
-
Annual energy consumption: User enters no of Days used.(365) 1.5 kWh × 365 = 547.5 kWh
-
Annual cost: The utility rate is 11 cents per kWh. (User enters utility rate as per his geography) 547.5 kWh × $0.11/kWh = $60.23/year
ALSO : Please find my attempt at writing the PSEUDO CODE in the JS file as comments. Can you please guide me if I am on the the right path.
What is working :Dropdowns
function configureDropDownLists(category, products) {
var refrigerators = new Array('Artic King AEB', 'Artic King ATMA', 'Avanti Compact', 'Bosch SS');
var dishWasher = new Array('Bosch - SHXUC', 'Asko DS', 'Blomberg', 'Amana');

Track the 4 buttons with an Event Listener (Estimated Daily Use)
Based on the above pass wattage to the formula (1,500 W × 1) ÷ 1,000 = 1.5 kWh Display and store 1.5 Kwh Make sure the Category and Products drop down don’t get reset. }
