9.9 LAB: Currency Conversion (jQuery) In this lab you will use jQuery to implement a currency conversion calculator that parses a JSON string format containing exchanges rates from US dollars (USD) to several other currencies. The exchange data and format is provided by: https://openexchangerates.org/ To complete the webpage, you must complete the following tasks: 1. Create a jQuery ready listener that updates the options within the element with ID toCurrency such that: 1. The first element is: Select currency 2. Only the currencies listed in the rates property of the exchange Rates object should appear in the dropdown 3. The element for each currency should show the full currency name followed by the currency's abbreviation in parentheses Ex: Canadian Dollar (CAN) 4. The value for each element should be the currency abbreviation 5. The allCurrencies object in the provided JavaScript template provides a mapping from all possible abbreviations to full currency name 2. Create a jQuery change listener for the select dropdown such that: 1. Convert the user-entered US dollars to the selected currency using the rates listed in the exchange Rates object. Display the converted currency with two decimal digits. Ex: If the user-entered US dollars is 100.00, Canadian Dollar (CAN) is elected, and the exchange rate is "CAD" 1.316853, the resulting converted currency is 131.69 2. Display the resulting converted currency by updating the readonly element with ID resultCurrency 3. Update the associated label for the resultCurrency element to the selected currency's full currency name, currency abbreviation in parentheses, and colon Ex: Canadian Dollar (CAN): 3. Create a jQuery click listener for the Update Rates button that: 1. Updates the exchange Rates object using the JSON string provided in the element with ID exchange Rates 2. Updates the select dropdown such that only the currencies listed in the rates property of the updated exchangeRates object appear in the dropdown 3. Resets the readonly <input> element with ID resultCurrency to display "To Currency 0:" 4. Resets the associated label for the resultCurrency <input> element to display
