A web page has a 'stock ticker' section where users can input the stock market abbreviation for a stock and have the current price of that stock show on the page.

For example, the stock market abbreviation for Microsoft is MSFT; if you type $"$MSFT$"$ into the text input element and press the button, the code will get the current price for Microsoft stock and display it$.$ A timer is then used to continuously check and update the stock price.

Write the code to implement this functionality using AJAX asynchronous programming.

$$ When the button is clicked, an interval timer is started that asynchronously gets the current price from a database every minute $(60,000$ miliseconds$).$

$$ On the server, there is a PHP file called "get $\_$quote.php$"$ that queries a stock market database for current prices. The SQL statement to get the current stock price is

"SELECT curr$\_$price FROM Stocks WHERE stock$\_$abbrev $=($abbreviation$)$;

$$ The return value from the database is a single value representing the stock price in dollar and cents format e$.$g$."123\mathrm{.}45".$ Use this value from the database to set the value of the element with id$=$"stockValue".

$$ If the stock abbreviation is spelled wrong or otherwise does not exist, the database returns zero rows. If this occurs, write "incorrect stock abbreviation" in the element for the stock value.

$$ The file format templates are provided, fill in the code where indicated.
